The single most valuable piece of evidence in a transvaginal mesh case is the device identification sticker placed in your operative report at the time of implantation. This label identifies the manufacturer, device name, catalog number, and lot number — establishing exactly which defendant's product caused your injuries. If you cannot locate this document, your attorney can obtain it through a medical records request directly to the implanting hospital.

Other critical evidence includes: operative reports from any revision or removal surgery; imaging studies (MRI or ultrasound) showing mesh position, erosion, or migration; records from specialists (urogynecologist, pelvic floor PT, colorectal surgeon) documenting mesh-related complications; pharmacy records for medications prescribed for mesh pain or infection; and personal journals or diaries documenting how mesh complications affected your daily life, relationships, and mental health.
