Patent number: 8613763Abstract: A multiple-sided medical device comprises a frame comprising wire or other resilient material and having a series of bends and interconnecting sides. The device has both a flat configuration and a second, folded configuration which a generally serpentine shape. The device is pushed from a delivery catheter into the lumen of a duct or vessel and may include one or more barbs for anchoring purposes. A full or partial covering of fabric or other flexible material such as DACRON, PTFE, or a collagen-based material such as small intestinal submucosa (SIS), may be sutured or attached to the frame to form an occlusion device, a stent graft, or an implantable, intraluminal valve such as for correcting incompetent veins in the lower legs and feet.Type: GrantFiled: October 27, 2008Date of Patent: December 24, 2013Assignees: Cook Medical Technologies LLC, Cook Biotech Incorporated, Oregon Health Science UniversityInventors: Dusan Pavcnik, Frederick S. Keller, Josef Rosch, Thomas A. Osborne, Brian L. Bates, John A. DeFord, Christopher G. Dixon, Andrew K. Hoffa, Raymond B. Leonard, II, Joseph F. Obermiller

Patent number: 5800456Abstract: A self-expanding endovascular stent formed of stainless steel wire which is bent into an elongated zigzag pattern. The zigzag pattern has a plurality of substantially straight wire sections of various lengths separating a plurality of bends. The zigzag pattern is helically wound about a central axis to define a tubular shape such that a majority of the bends are disposed in a helix. Adjacent bends in the helix are interconnected with a filament. The stent is capable of being radially compressed such that the straight wire sections and the bends are tightly packed around a central axis. The stent resiliently self-expands to assume a tubular shape when released from the compressed state. Depending on the pattern of the lengths of the straight wire sections in the zigzag pattern, the final tubular shape can be made irregular to match a patient's vascular system. In other words, the diameter of the tube which is defined by the stent can be made to vary along the length of the stent.Type: GrantFiled: June 13, 1997Date of Patent: September 1, 1998Assignee: Cook IncorporatedInventors: Munehiro Maeda, Hans A. Timmermans, Barry T. Uchida, Josef Rosch
