About Corza Medical
Corza Medical is a global medical technology company that manufactures surgical technologies for clinics, surgeons and OEM customers. The portfolio comprises surgical sutures (including Quill® barbed sutures, Sharpoint®, Look™), biomedical textiles (Pearsalls) including Texera™ braiding technology based on UHMWPE, ophthalmology instruments and single-use packs (Katena®, Blink™), microsurgical knives, and the fibrin sealant patch TachoSil®. Manufacturing includes braiding with 8/12/16 carriers, knitting, hand assembly of medical devices, and coating with silicone, wax, dyes and collagen in ISO-13485-controlled environments; annually over 150 million meters are braided and over 2 million hand-sewn devices are produced. Fiber materials used are polypropylene, polyester, nylon, UHMWPE, silk, and absorbable polymers such as PDO and polyglycolic acid. The company, headquartered in Boulder, CO (Global HQ) with EMEA HQ in Zurich, serves customers with over 3,000 employees in more than 80 countries; in Germany it has a site in Jestetten. In biosurgery, the divestiture of the business unit to EQT was agreed in 2026.
