Cincinnati Medical Device Attorney

investigating device injury & complications

Technological advancements in medical science have delivered hundreds of new medical devices in recent years. When they are necessary for ailing patients, health care providers and patients rely on the judgment, honesty, and skill of medical device manufactures to offer safe products. However, not all of these medical devices have been tested, and many have proved defective, injuring thousands of patients who trusted the companies who marketed the so-called safe products.

Because many of the medical devices on the market may be inadequately tested and rushed to the consumer to make a profit, victims and attorneys have filed many claims against the responsible companies. When manufactures are negligent and injure patients with defective medical devices, litigation is often necessary to restore the financial and human loss that is endured.

Although the U.S. Food and Drug Administration (FDA) is responsible for making sure that medical devices are adequately tested, device recalls have become increasingly common. Device manufacturers are often slow to respond to consumer complaints and must be held responsible for injuries caused.

Defective medical device litigation provides answers when medical device companies are unwilling to be honest with consumers and their physicians about the risks and dangers of their products. 

Many medical device companies have been involved in medical device litigation for defective produce designs and failure to adequately warn claims.  The litigation often precedes a voluntary recall.  Many critics have argued that the lenient FDA 510K process is partly to blame for the increase in medical device defects and injuries reported. 

The Lyon Firm is investigating the following types of device injury cases:

Medical Device Recalls

Companies should voluntarily issue a recall when a medical device has an unacceptable high rate of failure or complication. According to plaintiffs and attorneys, defective medical devices may only be recalled after they are known to cause serious health problems or targeted by lawsuits. Last year, millions of medical device units were recalled by the U.S. Food and Drug Administration (FDA). In 2018, even more medical devices have been recalled than in all of 2017. This is a concerning trend.

FDA Approval Process for Medical Devices

There are two types of processes where a manufacturer can gain access to the U.S market to sell medical devices: Premarket Approval Process (PMA);  and a 510 (k) process. It is important to understand the difference between these approval processes, as the types of testing done for each process is vastly different. 

Many device models are put to market under the more lenient 510K pre-approval process and not properly tested, putting American consumers and recipients at risk of serious injury. 

Many defective, untested devices are approved by the U.S. Food and Drug Administration (FDA) each year because in some cases the agency does not require clinical trials if the device is deemed similar to an existing medical device already on the market. This results in many recalled products each year and many preventable injuries and deaths for American patients. There are two ways in which the FDA can approve a medical device for marketing and sale in the United States:

  1. The pre-market approval (PMA) process requires a medical device company to submit safety and efficacy data on the proposed device. It is a longer and more expensive process. Typically, these products include innovative, cutting-edge technology. Because they are considered so crucial to the medical community, these products are usually immune from lawsuits.
  2. The 510K approval process, however, allows medical devices to obtain FDA approval without submitting safety and efficacy testing data. A company may introduce a new medical device if the device is a “substantial equivalent” to another device that previously went through the more rigorous Pre-Market Approval process discussed above. There is no immunity for medical products that go through the 510K process, and many lawsuits are filed each year against those companies manufacturing and marketing defective devices.

Medical Device Injury Settlements

When a company injures patients with defective medical devices, a medical device lawyer may help you recover financial losses, medical expenses and other damages incurred through litigation.

Defective Medical Device litigation involves complex science, and requires both legal and medical experts to effectively build a case on a personal or class action scale. In widespread device failures, there is often coordination amongst counsel around the country to correctly assess and distribute liability. The evidence necessary to prove a medical device company is liable for damages includes the following:

The Defective Product—it is important to preserve the product in order for experts and medical professionals to make certain arguments. It is critical to preserve all physical evidence and medical records.

Regulatory Documents—documents obtained from the U.S. Food and Drug Administration can prove insightful in understanding how the device was approved, any past adverse events reported by physicians and consumers, any warning letters issued to the company, and any testing that was or was not performed prior to marketing.

Corporate Documents—attorneys coordinate to compile and review company documents for relevant materials. In the past, internal admissions of negligence have been discovered at this point.

Corporate Representative Depositions—the defending medical device companies named in the lawsuit will be asked to designate individuals to testify on certain topics ranging from regulatory affairs, science and research, marketing and sales, and post-market surveillance.

Expert Witnesses—each party will designate experts to review and draw professional conclusions from certain pieces of evidence. Each party may challenge the basis of the expert’s opinion to preclude the submission.

Treating Physicians and Implanting Surgeons—if there is a claim based on a device warning, a physician or surgeon may need to testify that a different warning or instruction would have changed the manner in which the device was used, thereby preventing injury.

Demonstrative Evidence—computer graphics and other visuals are critical in assisting the jury to understand the medical science, the device, the risks and the injury suffered.

If you or a loved one suffered an injury due to a defective medical device and have questions about the legal remedies available to improve quality of life and medical care, contact The Lyon Firm. You will speak directly with Mr. Lyon, and he will help you answer these critical questions.

Why is Defective Medical Device Litigation Important?

When defective medical devices injure patients, product liability litigation helps to inform physicians of the true risk of the product, improves patient safety through recalls and design changes, and provides compensation to those injured.  

Medical Device Litigation Informs Physicians

The design defect and failure to warn claims often focus on the company’s lack of testing prior to putting the medical device  on the market market.  Failure to warn claims typically arise from the medical device company failing to adequately warn about the failure or complication rate in the instruction for use that is provided to the physician. 

Many doctors are not fully informed of the risks of the products by corporate sales representatives. Therefore, Medical Device Litigation also informs treating physicians about what the companies knew and tested for regarding the risks of the products. 

When the implanting surgeons are deposed, they are shown corporate documents and studies containing safety information that was never disclosed to them prior to recommending the product to the patient. Often this data includes critical information related to efficacy and higher complication rates with the device.  

Surgeons frequently testify that had they known the adverse safety data, they would not have recommended the device for the patient. 

Medical Device Litigation Leads to Safer Products

Many medical device cases have had a positive impact on public health and safety, and resulted in product design changes, recalls, and enhanced warnings as a result of litigation. In other words, defective medical device lawsuits make products safer so more families do not suffer the same adverse events. 

Medical Device Litigation Provides Compensation

Medical device lawsuits also provide for a sense of justice to the families with compensation and financial security for future medical care and lost income


Defective Medical Device Questions

How is a Medical Device Defined as Defective?

Ohio Definition of Defective

Under Ohio law, a medical device is  defective if it is unreasonably dangerous for its intended use. A legal cause of action can be based on several types of medical device product defects. Most jurisdictions a version of one or more of these cause of actions. 

(1)  Manufacturing/ Construction Defect of the medical device:

(2) Defective design and/or formulation of the medical device:

(3) Failure to warn or inadequate warning or instruction associated with the medical device:

(4) Misrepresentation on the Safety or Efficacy of the Medical Device:

(5) Fraud Related to the Safety or Efficacy of the Medical Device

(6) Negligent Distribution or Testing of the Medical Device

How do you prove design defect in a medical device lawsuit?

Defective design medical device cases arise not because a mistake was made during the manufacturing process, but rather the original design of the product is unreasonably dangerous. A “risk-benefit analysis” is used to determine whether safer/less expensive alternative designs were available to the manufacturer (e.g. the metal on metal design, the porosity and stiffness of transvaginal mesh )

For these claims, the FDA Review process is critical on whether a pre-emption defense exists.  For devices that went through the PMA (pre-market approval process), rather than the 510K process, the case must be evaluated very carefully for any parallel claims under state and federal regulations (e.g., failure to warn or failure to disclose adverse events) that can advance the case forward.  Without a careful legal analysis, the case may be subject to dismissal even where the medical device design proves to be defective. 

Risks:  The following factors are considered under Ohio law when determining the risks associated with the design of a medical device:  (1) the magnitude of the risk of injury; (2) ordinary consumer awareness of the risk for injury; (3) the likelihood of causing injury; (4) the violation of a private or public standard; and (5) the consumer’s expectation of the performance of the product and level of danger. Ohio Revised Code 2307.5 (B) Product Defective in Design or Formulation. These factors are considered in most other jurisdictions. 

BenefitsThe following factors are considered under Ohio law when determining the benefits associated with a medical device: (1) the utility of the product; (2) availability of an alternative design; (3) the magnitude of risks associated with an alternative design. Ohio Revised Code 2307.5 (c) These factors are considered in most other jurisdictions. 

Defenses for Defective Design(1) a pharmaceutical drug or medical device is not defective by design if it contains an adequate warning of an unavoidably unsafe aspect of the pharmaceutical or medical device; (2) the dangerous aspect is inherent to the product, recognizable, and cannot be eliminated without compromising the product’s usefulness; (3) a lack of a feasible alternative design. 2307.75 (d)(e)(f).

What is a manufacturing defect in a medical device lawsuit?

A manufacturing defect claim arises where the medical device is released from the factory in a manner that deviates from the intended design or specifications. 

Most manufacturing defect cases are based on a products deviation from the intended specification, formula, performance standards, or design model. In such cases, it may be easy to determine the product did not comply with the intended design. In defective medical device cases, the manufacturing defect is often related to performance standards (e.g., the metal does not meet the strength specification or has microscopic fractures–these defects require an examination by a qualified metallurgist who can examine the medical device).

As a result of the deviation, the product enters the market in an unreasonably dangerous condition and the consumer is exposed to or purchases a product that is defective. Any personal injuries or economic loss that arise from the the defect are compensable under Ohio product liability law.

The product may be recalled as a specific lot is identified as being non-compliant and defective. A product may be defective in manufacture or construction, materials and assembly, and a manufacturer or distributor may be subject to strict liability, even though it exercised all possible care.  Ohio Revised Code 2307.74.

What is a failure to warn claim in a medical device lawsuit?

All medical device products come with  warnings and instructions for use that are provided to the physician. If the company does not provide the physician with all the relevant safety data so that the physician adequately understand the risks and benefits of the product, then the medical device is defective. 

The physician must be in a position to pass the appropriate safety data onto the patient, so the patient can make an informed decision on whether they wish to have the medical device implanted.  Patient informed consent is critical because many devices are designed to be permanent.  

Litigation arises where there is evidence the medical device manufacturer failed to timely update a warning in light of new data or simply ignored the risk and failed to conduct sufficient research to identify and then disclose the risk.

In determining whether a medical device is defective due to inadequate warning or instruction, evidence must be presented to prove:

  • The medical device manufacturer knew, or in the exercise of reasonable care, should have known about a risk
  • A reasonable medical device manufacturer would have provided a warning of the risk
  • The medical device manufacturer failed to provide the warning
  • The patient was injured due to a lack of warning. The same elements apply whether the claim is based on a warning present during the marketing or post-sale warnings.

Defenses to Failure to Warn Claims(1) the risk was open and obvious or a matter of common knowledge; and (2) in cases of a pharmaceutical drug or medical device, the warning was provided to the prescribing physician (“Learned Intermediary Doctrine”).

What government agency regulates the recall of a medical device?

Design and manufacturing defects result in medical device product recalls each year in the United States, initiated by federal safety agencies.

  • The Food and Drug Administration (FDA)
  • The Consumer Product Safety Commission (CPSC)

The foregoing listed government agencies may initiate recalls of dangerous products but do not provide remedies or compensation for damages where an individual is injured due to the defective product. Only litigation can utilized to compensate patients injured by a defective medical device.

Nationwide Consolidation in U.S. District Court, Northern District of Ohio. The Depuy ASR Hip design was plagued with problems related to premature loosening and metallosis, caused by chromium and cobalt entering the blood stream.

The resulting injuries were a result of the metal-on-metal friction inherent with the design of the product. Depuy recalled the ASR and entered into a global settlement valued at $2.5 Billion to cover an estimated 8,000 patients.

The Lyon Firm represented several clients in the original settlement and continues to be active in this litigation. The settlement funds provided compensation for the revision surgeries, including compensating for medical costs, lost wages, and pain and suffering.



Nationwide Consolidation in U.S District Court, Northern District of Indiana. Similar to the Depuy ASR, the Biomet metal-on-metal hip design allegedly contributed to premature hip failures and metallosis due to the metal friction.

Biomet entered into a global settlement valued at $56 million to cover a few thousand claims. The Lyon Firm represented several plaintiffs in the original settlement and continues to be active in this litigation  on behalf of clients that did not participate in the national settlement.
