Shelhigh

Shelhigh was a medical device company that specialized in the development and manufacturing of bioprosthetic implants for cardiovascular and thoracic surgeries. The company's portfolio featured heart valves, surgical patches, and conduits made from bovine pericardium, utilizing a proprietary "No-React" detoxification process designed to enhance biocompatibility and prevent calcification. In 2007, the U.S. Food and Drug Administration (FDA) initiated a massive seizure of all Shelhigh products due to critical deficiencies in sterile manufacturing and quality control. This regulatory intervention effectively halted the company's commercial activities in the United States. Despite legal challenges from the company, the FDA's actions were upheld, leading to the company's eventual dissolution.
