Abstract: A heart valve occluder includes a ring of hard, wear-resistant material such as isotropic, pyrolytic carbon embedded in a plastic matrix with the outer circumference of the ring protruding from the plastic about the entire circumference of the occluder. By this arrangement, the wear rate on the edge of the occluder is improved, while the noise of the occluder striking the struts of its cage is reduced.

Abstract: A prosthetic heart valve is disclosed having a support ring which carries means for retaining a movable closure element in positions adjacent one side of the ring. The support ring has a fabric wrapping which defines, as a suturing element, an annular protrusion of fabric of double thickness extending from the side of the ring which is opposite the side adjacent the closure element.

Abstract: A clamp for securely holding ends of tubing together in end-toend relationship is disclosed, in which the tubing so held carries a flange about its end. The clamp comprises four separable sections of identical shape, in which each section has means for locking together with another section to form two identical clamp halves. Each clamp half defines a bore to receive and hold tubing. The bore has an enlarged portion to receive and hold the tuning flange. Each clamp half also defines arms and slots positioned so that the arms of each clamp half are capable of engaging the slots of the other clamp half to secure the two halves together with the tuning ends mounted in each clamp half being secured together in end-to-end relationship.
