Publication number: 20190083103Abstract: A medical device may include a catheter, an expandable member, a cover, and an actuator. The catheter may include a longitudinal axis, proximal and distal ends, and a cover lumen extending from the proximal to the distal end. The expandable member may include proximal and distal ends and may be disposed on a distal section of the catheter. The cover may include a first region that may be disposed along the expandable member, and a second region that may extend along a length of the catheter beyond the proximal end of the expandable member towards the proximal end of the catheter. A first end of the cover may invert into the cover lumen. The actuator may be coupled to the first end of the cover and configured to move the first end of the cover towards the proximal end of the catheter along the longitudinal axis of the catheter.Type: ApplicationFiled: September 21, 2017Publication date: March 21, 2019Inventors: Michael Broyles, Bret J Kilgrow

Patent number: 10195064Abstract: The present disclosure includes an endoprosthesis delivery system comprising an elongate member, such as a catheter, an endoprosthesis, a covering member disposed about the endoprosthesis, a tip, and an end cap. The tip and end cap can be integral to each other. The covering member can extend beyond the distal end of the endoprosthesis and onto the end cap. The end cap can comprise a tapered profile, which may assist in retraction of the catheter tip and end cap into an outer sheath. The end cap can further comprise one or more fins.Type: GrantFiled: August 13, 2015Date of Patent: February 5, 2019Assignee: W. L. Gore & Associates, Inc.Inventors: Bret J. Kilgrow, Larry J.

Publication number: 20180296377Abstract: An improved medical device reduces the loss of longitudinal length during expansion of a stent-graft from a compressed state to an expanded state. For example, the stent-graft is placed over a cover that provides resistance to expansion of the balloon during inflation, which reduces longitudinal compressing forces exerted on the stent-graft.Type: ApplicationFiled: November 25, 2015Publication date: October 18, 2018Inventors: Jane K. Bohn, Cody L. Hartman, Deenu G. Kanjickal, Bret J. Kilgrow, Joseph B. Koenig, James J. Nickerson, Thomas G. Triebes

Patent number: 10080643Abstract: A vascular graft incorporating a stent into a portion of its length. While various materials may be used for the vascular graft, the graft is preferably an ePTFE graft. The stent is preferably a self-expanding stent, although it may alternatively be a balloon expandable stent. The vascular graft preferably has a continuous inner tubular liner that extends between the opposing ends of the graft and provides a continuous luminal surface for blood contact that is uninterrupted by seams or joints. The length portion of the graft that does not include the stent has a greater wall thickness than does the portion including the stent.Type: GrantFiled: February 25, 2016Date of Patent: September 25, 2018Assignee: W. L. Gore Associates, Inc.Inventors: Edward H. Cully, Deenu Kanjickal, Bret J. Kilgrow, Larry J. Kovach, Timothy T. Stringer

Publication number: 20180049898Abstract: An open stent (a stent having open space through its thickness at locations between the ends of the stent), incorporating flexible, preferably polymeric, connecting elements into the stent wherein these elements connect adjacent, spaced-apart stent elements. Preferably the spaced-apart adjacent stent elements are the result of forming the stent from a helically wound serpentine wire having space provided between adjacent windings. Other stent forms such as multiple, individual spaced-apart ring-shaped or interconnected stent elements may also be used. The connecting elements are preferably longitudinally oriented.Type: ApplicationFiled: March 9, 2017Publication date: February 22, 2018Inventors: Joseph R. Armstrong, Edward H. Cully, Mark Y. Hansen, Brian L. Johnson, Bret J. Kilgrow, Larry J. Kovach, James D. Silverman

Patent number: 5192483Abstract: A method of forming a suture needle holder for a suture needle. A suture needle is placed in a trough cut into the surface of a die. This trough intersects a cavity within the die. A sheet is placed onto the surface of the die after the needle is placed in the trough. The sheet is then thermoformed into the cavity to form a pedestal around the needle. During thermoforming the needle is captured by the sheet and a slot is formed about the suture needle.Type: GrantFiled: December 2, 1991Date of Patent: March 9, 1993Assignee: W. L.
