Patent number: 8444687Abstract: 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 using heat or pressure welding crimping, adhesive, or other techniques 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: February 26, 2009Date of Patent: May 21, 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, Christopher G. Dixon, Andrew K. Hoffa, Raymond B. Leonard, II, Joseph F. Obermiller, John A. DeFord, Joseph W. Roberts

Patent number: 6530951Abstract: A silver implantable medical device 10 includes a structure 12 adapted for introduction into the vascular system, esophagus, trachea, colon, biliary tract, or urinary tract; at least one layer 18 of a bioactive material posited on one surface of structure 12; and at least one porous layer 20 posited over the bioactive material layer 18 posited on one surface of structure 12 and the bioactive-material-free surface. Also included is a layer or impregnation of silver 45. Preferably, the structure 12 is a coronary stent. The porous layer 20 is comprised of a polymer applied preferably by vapor or plasma deposition and provides a controlled release of the bioactive material. It is particularly preferred that the polymer is a polyamide, parylene or a parylene derivative, which is deposited without solvents, heat or catalysts, merely by condensation of a monomer vapor. Silver is included as a base material, coating or included in a carrier, drug, medicament material utilized with the implantable stent.Type: GrantFiled: October 23, 1997Date of Patent: March 11, 2003Assignees: Cook Incorporated, MED Institute Inc.Inventors: Brian L. Bates, Neal E. Fearnot, Thomas G. Kozma, Thomas A. Osborne, Anthony O. Ragheb, Joseph W. Roberts, William D. Voorhees, III

Patent number: 5064428Abstract: A stone retrieval basket having superelastic metallic alloy wires attached to the distal end of an inner elongaged member tube for retrieving calculi and crushing them against an outer introducer tube percutaneously inserted into a patient. The basket comprises kink-resistant superelastic metallic alloy wires such as nitinol forming a bulbous shape for capturing calculi therein. The ends of the superelastic wires of the basket are attached to the distal end of a inner elongated member tube with the aid of sleeves crimped thereon, which are soldered or spot welded in recesses about the distal end of the inner tube. The outer tube is percutaneously inserted into the biliary or urinary system in which the basket is then inserted to capture large-sized stones. A peel-away sheath is also included to introduce the basket and inner elongatged member tube into the outer introducer tube.Type: GrantFiled: September 18, 1990Date of Patent: November 12, 1991Assignee: Cook IncorporatedInventors: Constantin Cope, Scott E. Boatman, Joseph W. Roberts

Patent number: 5057114Abstract: A medical retrieval basket having superelastic metallic alloy wires attached to the distal end of an inner elongated member tube for percutaneously capturing and removing calculi from a cavity or duct of a patient. The basket comprises kink-resistant superelastic metallic alloy wires such as nitinol which forms a bulbous shape for capturing calculi therein. The ends of the superelastic wires of the basket extend through the passageway of the inner elongated member tube and are attached to the proximal end of the tube. An outer elongated member tube is percutaneously inserted into the biliary or urinary system. The inner member tube is inserted through the outer member tube into a duct, cavity or organ of the patient. The distal ends of both the inner and outer member tubes have a predetermined longitudinal curvature for controlling the positioning of the basket and the tubes within the patient.Type: GrantFiled: September 18, 1990Date of Patent: October 15, 1991Assignee: Cook IncorporatedInventors: Gerhard R. Wittich, Scott E. Boatman, Joseph W. Roberts

Patent number: 4823525Abstract: A skylight structure offering superior water intrusion resistance has a glass plate superposed in spaced relationship above a plastic dome member having an integral inverted U-shaped flange. A cap marginally framing the glass and plastic members has spaced downwardly depending flanges with an inner shorter flange abutting the outer surfaces of the plastic flange and an outer longer flange spaced from and shielding the outer surfaces of the plastic flange. The outside lower end of the U-shaped flange is cured outwardly.Type: GrantFiled: September 13, 1988Date of Patent: April 25, 1989Assignee: Tub-Master CorporationInventors: Joseph W. Roberts, John C. Roberts, Gordon MacLeod

Patent number: 4548006Abstract: A self flashing skylight for installation on the downwardly sloping roof is disclosed, in which a central portion is convexly curved and the side edges are provided with channels adjacent the convexly curved portion so that rain water impinging on the skylight will tend to be diverted into the channels which direct the water to the bottom of the skylight.Type: GrantFiled: September 13, 1984Date of Patent: October 22, 1985Inventor: Joseph W. Roberts, Sr.
