Parietex hernia mesh lawsuit

Parietex hernia mesh devices: From bad to worse

The Parietex hernia mesh, which was designed and manufactured by the major medical-supplies corporation Covidien, is a case study in a company taking a bad, dangerous product and, by redesigning it, making it even worse and more dangerous.

It’s products like the Parietex hernia mesh that makes the attorneys at shake their heads in regret and astonishment. How could it ever have occurred to Covidien that the Parietex hernia mesh wouldn’t spark health problems and lawsuits?

The first Parietex hernia mesh device was made of polyester, whereas most other hernia mesh products are made of a plastic called polypropylene. Polypropylene has a dangerous tendency to dissolve into internal tissue, making it a main cause of many of the medical problems that hernia mesh patients have suffered. So making a hernia mesh from a material other than polypropylene sounds like a good idea.

Except that it’s not. Polyester – yes, the same material used in all those pants in the 1970s – also has a tendency to deteriorate, shrink, and deform when inside human body. Those structural problems with the Parietex hernia mesh can cause a number of serious health issues, such as adhesions, infections, and compromised internal organs.

The tendency of the Covidien Parietex hernia mesh to shrink poses particularly nasty problems. When the Parietex shrinks, it often tugs on the tissue to which it is attached. Not only can the mesh tear when it shrinks, but it can cause severe pain when it yanks on the internal organs.

If the Parietex hernia mesh shrinks sufficiently small, it can become detached from the site where it’s been implanted, and can actually migrate throughout the body to places where it can do even more serious damage.

Covidien’s redesign of this potentially injurious device made matters even worse.

The Parietex Composite hernia mesh, or PCO, is made of that same polyester, but it is coated with a “barrier” of collagen. Collagen is a protein found in connective tissue all throughout the body, and it’s used in many medical and cosmetic products. The purpose of the PCO’s collagen barrier was to prevent the mesh from adhering to internal tissues.

In this case, however, collagen didn’t help at all. In fact, it made things worse.

After the Covidien Parietex Composite hernia mesh is implanted, the collagen layer dissolves very quickly, so it’s not even around long enough to prevent the mesh’s polyester from adhering to internal tissues and organs. Once the collagen is gone, patients are stuck with the same old polyester mesh with the potentially hazardous tendency to rip, to tear at and cause pain in internal tissues, and to migrate to other locations in the body.

Why is this worse? Because patients were promised a safer product, and instead received the same old thing – now with an utterly useless coating. Thanks, Covidien.

So Covidien went back to the drawing board and came up with a device that is so bad and so dangerous that it makes you wonder if they wouldn’t have had greater success in the Medieval Era, when they would surely have been every cruel tyrant’s preferred maker of torture devices.

The Parietex ProGrip and the Parietex Plug and Patch System are hernia mesh products that amplify all the bad things about the other Parietex products.

These devices are, once again, made of polyester, a fabric that has a tendency to shrink, tear, and deform. This time, the polyester is woven together with a polylactic acid layer (PLA), which, once again, was supposed to prevent shrinkage. It didn’t work.

The Parietex ProGrip is particularly noted for causing pain in the patients in whom it has been implanted. The ProGrip is a “self-fixating” mesh: it has thousands of tiny hooks that are intended to keep the hernia mesh in place. The problem is that the polyester of the mesh still shrinks. And when it shrinks, those thousands of tiny hooks yank and tug on the tissue to which they are attached, causing severe pain.

The hooks are effective, though. They’re so good at keeping the ProGrip in place that the thing just won’t let go. But since it causes such severe pain, surgery is often necessary to remove it. Sometimes multiple surgeries.

The attorneys at believe that Parietex hernia mesh products are among the worst and most dangerous hernia mesh products ever made. Their design flaws mean that Parietex hernia mesh products cause far more harm than good.
