Publication number: 20240016634Abstract: Embodiments include a delivery device for an auxetic device. The delivery device is comprised of an outer constraining device and a longitudinal controlling device disposed concentrically within the outer constraining device and offset to form a chamber for receiving the auxetic device. A mechanism coupled to the outer constraining device and the longitudinal controlling device allows the chamber size to adjust longitudinally as the auxetic device is deployed. Other embodiments may be described and/or claimed.Type: ApplicationFiled: October 13, 2021Publication date: January 18, 2024Applicant: OREGON HEALTH & SCIENCE UNIVERSITYInventors: Ramsey Al-Hakim, Khashayar Farsad, John A.

Patent number: 11554006Abstract: A removable blood clot filter includes a number of locator members and anchor members disposed radially and extending angularly downward from a hub. The locator members include a number of linear portions having distinct axes configured to place a tip portion approximately parallel to the walls of a blood vessel when implanted to apply sufficient force to the vessel walls to position the filter near the vessel centerline. The anchor members each include a hook configured to penetrate the vessel wall to prevent longitudinal movement due to blood flow. The hooks may have a cross section sized to allow for a larger radius of curvature under strain so that the filter can be removed without damaging the vessel wall.Type: GrantFiled: June 22, 2020Date of Patent: January 17, 2023Assignee: C. R. Bard Inc.Inventors: Robert M. Carr, Jr., Andrzej J. Chanduszko, John D. McDermott, John A. Kaufman

Patent number: 9414843Abstract: Described are devices, methods and systems useful for achieving occlusion of vascular vessels. Percutaneous procedures are used to occlude and obliterate the greater saphenous vein, for example in the treatment of varicose vein condition caused by venous reflux. Certain embodiments encompass the deployment of one or more vascular occlusion devices via a through-and-through percutaneous procedure that leaves the vascular occlusion device or devices in a through-and-through condition.Type: GrantFiled: May 26, 2006Date of Patent: August 16, 2016Assignees: Cook Medical Technologies LLC, Cook Biotech Incorporated, Oregon Health & Science UniversityInventors: Dusan Pavcnik, John A.

Patent number: 8444666Abstract: A filter may have an apical hub and a plurality of divergent legs. A first attachment member may be separate from, but attached to the second end of at least one of the plurality of divergent legs. A second attachment member may be separate from, but attached to a stent. The first and second attachment members may be separate from, but attachable to one another to releasably attach the filter to the stent. One of the first attachment member and the second attachment member may include an attachment wire that is positioned in a lumen of a tubular member or one of the first attachment member and the second attachment member may comprise a cannula. In some implementations, an upward motion applied to the retrieval connection member may disengage at least one attachment wire of the first attachment member from the second attachment member.Type: GrantFiled: September 12, 2003Date of Patent: May 21, 2013Assignee: Cook Medical Technologies LLCInventors: Dusan Pavcnik, Brian C.
