Abstract: A prosthetic graft for arterial system repair comprising a flexible tube, an anchoring device attached at each of the two opposite ends of the flexible tube member, each anchoring device containing a ring, a circular member and a connecting member, in each anchoring device, the ring is connected to and defines an opening into one of the opposite ends of the flexible tube member, the circular member is spaced apart from the ring delimiting a space therebetween and the connecting member is affixed to the ring and the circular member spacing apart these two members.

Abstract: Three embodiments of an improved endoscope: The first embodiment is composed of a flexible tube member, the proximate end portion of which is attached to and in optical communication with a control unit; and, a second flexible tube member partially circumscribing the first tube member, one terminal end portion of which is (i) affixed to the outer surface of the first flexible tube at a point other than the distal portion and (ii) adapted to expand and contract along its own and the longitudinal axis of the first flexible tube member. The second embodiment contains a control unit, first, second and flexible tube members and in addition a third tube member. The third tube member has (i) a terminal portion affixed to the first tube member at a point other than at a distal portion and (ii) the balance thereof spaced apart from and circumscribes a part of the first and a portion of the second flexible tube member. One terminal free end of the second flexible tube is slideably received within the third tube member.
