Interchange Medical

Interchange Medical was a medical technology company specializing in the development of advanced percutaneous access systems designed to minimize infection risks associated with long-term indwelling devices. The company's flagship product, the Interchange™ Percutaneous Access Device, featured a proprietary porous surface architecture intended to facilitate biological integration and tissue ingrowth at the skin-device interface. By creating a stable 'living seal,' the technology aimed to prevent the migration of bacteria along the tracks of catheters and drivelines, a major cause of morbidity in patients requiring ventricular assist devices (VADs) or chronic dialysis. Founded by Dr. George Picha, a pioneer in biomaterials, the company's innovations addressed critical unmet needs in chronic wound care and infection control before its operations were largely transitioned to related ventures.
