Publication number: 20220370057Abstract: A method for closing a puncture in tissue that includes advancing a guide member into proximity with the tissue, the guide member having a needle guide, positioning a distal end of the guide member with the needle guide toward the tissue to present an opening of the needle guide toward the tissue the needle guide cooperating with a suture securing device that is slidably coupled to the guide member and a suture attached to the suture securing device, deploying the suture securing device, the suture securing device comprising a body with an anchor point for the suture and features that allow the suture securing device to pierce the tissue and resist retraction through the tissue, and establishing tension in the suture to move the suture securing device toward another suture securing device to thereby close the puncture in the tissue.Type: ApplicationFiled: August 4, 2022Publication date: November 24, 2022Inventors: Marc G. Gianotti, Aaron M. Fortson

Patent number: 9486191Abstract: A vessel closure device is provided that may include a guide member, one or more needle guides disposed at least partially within the guide member, and an angle adjustment member movably attached to the guide member. The needle guides may be configured to move between a first position wherein the needle guides are substantially straightened at least partially within the guide member and a second position wherein the needle guides at least partially extend radially and distally away from the guide member. The angle adjustment member may be configured to move between a first position and a second position wherein the angle adjustment member can selectively deflect the needle guides radially toward the guide member when the needle guides are in the second position.Type: GrantFiled: May 20, 2011Date of Patent: November 8, 2016Assignee: ABBOTT VASCULAR, INC.Inventors: Marc G. Gianotti, Aaron M. Fortson

Publication number: 20130190856Abstract: Apparatus and methods for stenting are provided comprising a stent attached to a porous biocompatible material that is permeable to endothelial cell ingrowth, but impermeable to release of emboli of predetermined size. Apparatus and methods are also provided for use at a vessel branching. The present invention further involves porous polymer membranes, suitable for use in medical implants, having controlled pore sizes, pore densities and mechanical properties. Methods of manufacturing such porous membranes are described in which a continuous fiber of polymer is extruded through a reciprocating extrusion head and deposited onto a substrate in a predetermined pattern. When cured, the polymeric material forms a stable, porous membrane suitable for a variety of applications, including reducing emboli release during and after stent delivery, and providing a source for release of bioactive substances to a vessel or organ and surrounding tissue.Type: ApplicationFiled: March 13, 2013Publication date: July 25, 2013Applicant: Abbott Laboratories Vascular Enterprises LimitedInventors: Randolph von Oepen, Gerd Seibold, Silvio R.

Publication number: 20100299911Abstract: Method for manufacturing an endoprosthesis are described. The method may include selecting an indication range based on a range of inner diameters of a body lumen. A nominal diameter of the endoprosthesis may be selected. A range of chronic outward force, a range of radial force, a range of safety factors, or combinations thereof may be selected. A design characteristic may be determined based on the indication range, the nominal diameter, and at least one of the range of chronic outward force, the range of radial force, and the range of safety factors. The endoprosthesis may be manufactured based on the determined design characteristic.Type: ApplicationFiled: May 12, 2010Publication date: December 2, 2010Applicant: ABBOTT CARDIOVASCULAR SYSTEMS, INC.Inventors: Marc G.
