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: 10512531Abstract: A filter delivery device for implanting a vessel filter within a blood vessel of a patient's body. The filter delivery device includes a mechanism for preventing hooks and/or legs on a vessel filter from entangling with each other while the vessel filter is loaded within the delivery device. In one variation, the filter delivery device includes a delivery catheter with grooves at the distal end lumen opening. When a vessel filter with radially expanding legs is compressed and inserted into the distal end of the delivery catheter, the hooks on the distal end of the legs are received and separated by the corresponding grooves on the delivery catheter. In another variation, a pusher rod, with a receptacle for receiving the hooks, is positioned within a delivery catheter to prevent the entanglement of the hooks and/or legs of a filter loaded within the delivery catheter.Type: GrantFiled: June 26, 2017Date of Patent: December 24, 2019Assignee: C. R. BARD, INC.Inventors: Alexander W. Tessmer, David G. Spilka, David W. Rauch, Andrzej J. Chanduszko, Robert M. Carr, Jr.

Patent number: 10172702Abstract: A vascular graft with trim lines is described, the trim lines providing a guide for precision shaping of the cuff. The trim lines may be printed or otherwise disposed on a surface of the cuff or included on a template designed for disposition over the cuff. The trim lines may also be disposed on a side of a pocket into which the cuff is positioned for trimming. Also described is an apparatus and method for precise trimming of a vascular graft.Type: GrantFiled: November 21, 2016Date of Patent: January 8, 2019Assignee: C. R.
