摘要： An annuloplasty ring prosthesis comprising a frame having an outer surface; and a cover surrounding the frame. The cover comprises a bioprosthetic tissue that can be regenerative or fixed and non-regenerative. The frame can be bioabsorbable or non-degradable. A ring prosthesis and a method of manufacturing a ring prosthesis is also provided. The ring prosthesis comprising an elongated rod member formed into a substantially ring shape, the elongated rod member being formed substantially from a flat bioprosthetic tissue.

摘要： A surgical pad can comprise a flexible pad portion configured to be positioned over an opening in a target tissue. A plurality of elongate ribs can be distributed across a surface of the flexible pad portion oriented away from the target tissue and can be coupled to the flexible pad portion. A surgical pad can comprise a central opening configured to be aligned with an opening in a target tissue, and a plurality of edge openings distributed around an outer edge portion. A method can comprise positioning a spacer between a target tissue and a surgical pad to adjust the tension of surgical cords secured to surgical pad. A method can comprise positioning a spacer between a surface of a surgical pad oriented away from a target tissue and portions of surgical cords secured over the surface of the surgical pad, to adjust the tension of the surgical cords.

摘要： A method of applying fibrous material to a medical device component involves coupling a medical device component a holder device, rotating a reservoir device containing a liquid polymeric solution to expel at least a portion of the liquid polymeric solution from an orifice of the reservoir device, the expelled at least a portion of the liquid polymeric solution forming one or more strands of fibrous material in a deposition plane, and rotating the holder device at least partially within the deposition plane to apply at least a first portion of the one or more strands of fibrous material to one or more surfaces of the medical device component, thereby forming a fibrous covering on the one or more surfaces of the medical device component.
