Abstract
Described embodiments are related to a prosthetic valve for surgical placement with a sewing cuff durably attached to a frame. The durability of the attachment is accomplished by sandwiching a fabric between the frame and a composite material. The fabric extends beyond the frame base to form a sewing cuff that is integral to a frame assembly. The sewing cuff facilitates tissue ingrowth while tissue ingrowth is discouraged elsewhere around the frame.
