C.R. Bard’s Sepramesh IP composite hernia mesh device was acquired from another medical device outfit, specifically for the Sepra® technology and to use in future mesh products of its own. Bard’s Sepra Technology (ST) is still used in the Ventralex ST, Ventrio ST, and Ventralight.

The Sepramesh IP composite mesh was approved by the FDA in 2000 through the agency’s 510(k) clearance program, similar enough to another mesh product already on the market, and was distributed widely to patients. Sepramesh IP, approved in 2004, is a modified version of the original device (Sepramesh IP Composite is made of the plastic-like materials polypropylene (PP) and polyglycolic acid (PEG).)

Regardless of new and “improved” designs, Sepramesh IP and other Bard mesh products have reportedly injured thousands of recipients with implanted mesh.

Victims and attorneys argue that Bard should have initiated better clinical testing programs and offered warnings of health risks before they marketed their products as safe.

Sepramesh Safety Issues & Complications

Bard’s Mesh devices have been associated with many common injuries and complications. 

At least 50 adverse event reports relating to Sepramesh have been submitted to the FDA by doctors and patients. Sepramesh IP has been shown to adhere to surrounding tissues and organs, including at least one patient’s colon.

Another reported an implant had created a holes in their bowel and eroded a small intestine. Other reported mesh complications and side effects linked to hernia mesh products include:

  • Bowel Blockage
  • Infection
  • Adhesion
  • Chronic pain
  • Hernia recurrence
  • Allergic reaction
  • Granuloma
  • Hematomas
  • Fistula formation
  • Bowel Perforation
  • Mesh erosion
  • Need for revision surgery

Sepramesh IP Composite Mesh Lawsuits

Sepramesh has been targeted for being manufactured with alleged defective materials. The implant is made of a lipid coating that may incite high levels of inflammation, and can slow wound healing and create chronic infection. In one study, after the mesh was implanted for only 8 days, postoperative peritoneal adhesions occurred at the extremities of the mesh where bare polypropylene was exposed.

Adhesions also formed where fixation sutures exposed the polypropylene. Lawyers involved in cases argue C.R. Bard is negligent and failed to warn the public about the potential risks of the mesh. Lawsuits also claim the following:

  • Bard is liable for designing and manufacturing a defective product
  • Bard failed to warn consumers of potential risks
  • Bard is liable for strict liability for manufacturing a defective product
  • Bard breached express and implied warranties

Hernia Mesh Litigation

Can I file a hernia mesh lawsuit?

Attorneys claim several hernia mesh devices were not properly tested before they were marketed and distributed as safe medical instruments.

The companies currently face thousands of pending hernia mesh injury lawsuits. If you have had surgery to treat a hernia using a device and you experience any signs or symptoms of recurrence of the hernia, please consult with a medical and legal expert. The Lyon Firm has experience litigating cases against medical device manufacturers.

Attorneys contend that some hernia mesh devices are not properly tested before they are distributed to the public as safe products. Device companies like Gore, Aspide, Ethicon, Bard, Covidien and Atrium have settled hundreds of lawsuits and currently face countless more injury claims.

If you are unsure about the mesh manufacturer and product used in your surgery and have questions about your hernia repair, contact your Ohio surgeon to obtain medical records. Contact a Cincinnati hernia mesh lawyer to discuss potential hernia mesh injury lawsuits and settlement.

What is a fistula?

Repair of hernias are done by either suture repair or prosthetic mesh repair. The latter is associated with a lower recurrence rate but a higher incidence of complications. The most serious complication is the development of fistula.

Fistula is a late complication of prosthetic mesh repair and is usually due to chronic erosion of bowel by mesh placed in direct contact with intestinal loops both in open and laparoscopic repairs. Symptoms of fistulas may include the following:

  •  Persistent pain—throbbing and worse when sitting down.
    •    Skin irritation around the anus, including swelling, redness and tenderness.
    •    Discharge of pus or blood.
    •    Constipation or pain associated with bowel movements.
    •    Fever
Does hernia mesh cause adhesions?

Hernia mesh adhesions are scar tissue resulting from hernia mesh operations and the healing process. Following hernia repair surgeries, adhesions may form in the abdomen or peritoneum. The mesh repairs usually heal quickly but when adhesions form, organs connected by the scar tissue may not function properly.

The popularity of hernia mesh operations has led to increasing concern regarding mesh-related adhesions. Adhesions result from the fibrin exudates that follow any kind of trauma.

These exudates form temporary adhesions until the fibrinolytic system absorbs the fibrin. Absorption is delayed in the presence of inflammation or foreign bodies such as mesh devices. In these situations, they develop into tissue adhesions.

All mesh implants produce adhesions, though their extent varies. Abdominal adhesions are a common complication, occurring in a majority of people who undergo abdominal or pelvic surgery. Adhesions cause the majority of small bowel obstructions in adults, and are believed to contribute to the development of chronic pelvic pain.

X-rays do not reveal potential mesh issues or diagnose the presence of adhesions. An additional surgery is usually needed to diagnose or treat hernia mesh adhesions. However, revision surgeries carry risks and can lead to further health problems, including infection, bowel blockage, bowel perforation and chronic pain.

Adhesions may begin forming long before they are noticed by patients or doctors. Depending on the location, adhesions from defective hernia mesh devices may cause pain and affect the bowel in different ways. Even removing a defective hernia mesh product may not completely solve all health issues.

Symptoms of adhesion and hernia mesh injury may include:

  •  Severe abdominal pain or cramping
    •    Vomiting
    •    Bloating
    •    Loud bowel sounds
    •    Swelling of the abdomen
    •    Constipation
