Pelvic Mesh: Your Device is Tracked. So Are You

The FDA requires Medical Device distributors to track your device up until and including your death—including your name, address, phone number and social security number. Title 21 of the FDA regulations require the device distributor, final distributor, or multiple distributors (devices that move from patient to patient), promptly upon purchase, provide the manufacturer the name and addresses of all distributors along its journey to you, including the lot number, the date the device was received, and the person from whom it was received.

Tracking Devices vs. Device Tracking

The last distributor before your implant must also provide the manufacturer with their own name and address, the unique device identifier (e.g. lot or serial number), your name, address, phone number and social security number—unless you refuse to release that information under 821.55(a).* They must also record the date of your implant, name, address, and phone of both implanting surgeon and regular physician, and the date the device was explanted.

If a patient dies, the end point distributor must provide the date of death, name, address, and phone of treating physician, date of any explant with contact information for explanting physician, and, where applicable, and the date the device was returned to the manufacturer, retired from use or disposed of in any other way.

* Any patient receiving a device subject to tracking may refuse permission to release their name, address, phone and social security number or any other identifying information but, the hundreds of pelvic mesh implantees who were not told they had an implant or that a tracking system exists, would have no way to refuse permission. Title 21 can override a patient’s right to privacy if the “health or safety of the patient requires that such persons have access to the information.”

Pudendal Nerve Injury Caused by Improper Insertion of TOT Obturator Tape – Pelvic Pain

The two main nerve complications TOT-injured women report in support groups are 1) pudendal and 2) obturator in that order. Because most studies do not evaluate for nerve injuries past 3-12 months, there is no scientific estimate of how common the injury is. Our experience is that it is extremely common. Pudendal injury causes persistent pain localized around the urethra and around the clitoris, irradiating to the one labia majora (maximum at the lower edge of symphysis) or both.

Polypropylene creates cripples when placed inside the pelvis.

The pudendal nerve is nowhere near the pathway of an obturator tape so how did the women get injured? The mystery may have been solved by three Czech investigators.

In 2011, Jaromir Masata & Petr Hubka & Alois Martan decided to look into why their patient, a 48 years old female obtained a pudendal nerve injury. After receiving a TVT-O, the woman experienced what the authors saw as an “atypical” postoperative pain that continued without relief for three years. While the authors treated her with injections and replaced her sling with yet another dubious tape, the work they did to track down the cause of her injury is valuable.

Authors circled scar and placed a “+” pointing to correct placement location.

The woman’s insertion scar (see Figure 1) was in the wrong place. By using a cadaver to trace the aberrant passage of her sling, the researchers found it intersected with the pudendal nerve. How many others were injured this way? Are you one of them? Was your transobturator tape placed incorrectly? If the manufacturer provided short videos and an instruction sheet, was that adequate training for your surgeon?

FDA Publishes 50 Known Pelvic Mesh Device Problems – Approves Anyway

The FDA received nearly 9,000 complaints about predicate devices before approving a new TOT. Here is a list from the January 2007 application for FDA clearance for the Align Urethral Support. This list does not include many device-related problems like bleeding, infection, pain, dyspareunia (inability to have sex) or those on the list in the right hand column on this page.

The Align (Bard Avaulta) was approved anyway on March 21, 2007.
