Abstract
A suturing ring to attach the body of an implantable heart valve to heart tissue by sutures is composed of a fabric containing an inorganic antimicrobial agent. The fabric can have a material coating the fibers of the fabric in which particles of the agent are embedded. The coating material can be elastomeric and the fabric porous, to improve its flexibility, or non-porous and the fabric ring can be coated with a tissue compatible substance such as collagen. One type of ring has an annular top part to fit over one of top and bottom surfaces of the valve body and defining an opening to the heart valve, a step wall depending from the annular top part to extend along said valve body wall and an outwardly extending flange through which the sutures are to be sewn.
