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.
An implantable heart valve having at least one heart valve mechanism and a suturing ring for suture attachment of the valve to heart tissue, wherein the suturing ring comprises a fabric and a coating material on said fabric, said coating material comprising a) a material selected from the group consisting of acrylic, polyurethane, silicone, latex, polyglycolic lactic acid, a biodegradable polymer, a hydrophilic biodegradable polymer, and a non-degrading polymer and b) an inorganic antimicrobial agent comprising a zeolite having ion-exchanged antimicrobial metal ions said zeolite being present at a surface of the suture ring such that inorganic antimicrobial metal ion are antimicrobially available.
An implantable heart valve having at least one heart valve mechanism, and a suturing ring for suture attachment of the valve to heart tissue, wherein the suturing ring comprises a fabric, the fibers of which are coated with an elastomeric coating material containing an inorganic antimicrobial agent comprising an inorganic antimicrobial metal ion component, said antimicrobial agent being present at a surface of the suture ring such that inorganic antimicrobial metal ion is antimicrobially available.
