U.S. Food and Drug Administration (FDA) investigators and U.S. Marshals today seized all implantable medical devices from Shelhigh, Inc., Union, N.J., after finding significant deficiencies in the company's manufacturing processes. The deficiencies may compromise the safety and effectiveness of the products, particularly their sterility.See the entire FDA alert here. So much for their No-React® Tissue Detoxification process.
The products include pediatric heart valves and conduits (tube-like devices for blood flow), surgical patches, dural patches (to aid in tissue recovery after neurosurgery), annuloplasty rings (to help repair heart valves) and arterial grafts. The tissue-based devices are used in many surgical settings, including open heart surgery in adults, children and infants, and to repair soft tissue during neurosurgery and abdominal, pelvic and thoracic surgery. Critically ill patients, pediatric patients and immuno-compromised patients may be at greatest risk from the use of these devices.
Maybe this explains these failures with their valves.
