When this site started ten years ago, its focus was on the injuries caused by polypropylene pelvic mesh.
Polypropylene or PP is a polymer that emerged from the petroleum industry. PP is THE material that has been used to make most pelvic and hernia meshes for decades.
Recipients claim it incites an inflammatory response, hides biofilm infection, can shrink and erode. A surgeon can unintentionally trap a nerve during placement, causing unrelenting pain.
Although it's debated, complications with PP mesh are see in upward of 30% of recipients from mild to life-altering.
PP is one of the dominant polymers used in the medical device industry alongside polyvinyl chloride (PVC) and polyethylene (PE). Because the price-to-performance ratio is very high, the market for PP is predicted to grow exponentially in the future.
We know from the many pelvic mesh trials that PP, used by manufacturers Johnson & Johnson, Boston Scientific, American Medical Systems, and C.R. Bard, is accompanied by a warning not to use polypropylene to make an implanted medical device.
The warning is contained in the Material Safety Data Sheet (MSDS) that accompanies the polymer. That warning is required by the Occupational Safety and Health Administration (OSHA) to protect workers in the manufacturing of any material.
It says specifically - “MEDICAL APPLICATION CAUTION: Do not use this Phillips Sumika Polypropylene Company material in medical applications involving permanent implantation in the human body or permanent contact with internal body fluids or tissues.”
It couldn’t be clearer.
What’s disturbing is that polypropylene mesh naturally will come into contact with both bodily fluids and tissues for the rest of that patient’s life.
Mesh makers have contended that “mesh is inert” and does not change once placed in the body, but experts at trial have shown with the help of an electron microscope, that PP continues to degrade and crack in the body.
In the upcoming January 10, 2022 trial in Ohio trial of hernia mesh recipient, Antonio Milanesi, naming defendant Bard, the Complaint lists the many complications alleged to accompany a PP hernia mesh. (Antonio Milanesi v. Bard 2:18-cv-01320, Do District of Ohio)
