Publication number: 20240138979Abstract: This document provides devices and methods for the treatment of heart conditions. For example, this document provides prosthetic heart valves and transcatheter heart valve replacement methods. The prosthetic heart valves can be configured into a low-profile configuration for containment within a small diameter delivery sheath. The prosthetic heart valves include can include a valve member attached to a stent frame. In some embodiments, the valve member is a molded biomaterial with a novel shape and resulting performance characteristics. Localized protective covering members can be attached to the stent frame to prevent the valve member from contacting the stent frame as the valve member cycles between its open and closed configurations.Type: ApplicationFiled: January 11, 2024Publication date: May 2, 2024Inventors: Jason Quill, William Leon Neethling, Christopher B. Brodeur, Ramji Iyer, Kaitlyn Roth

Patent number: 10555753Abstract: The present invention provides an atherectomy catheter which has a cutting element that is able to cut both soft tissue and hard tissue, and methods of cutting material from a blood vessel lumen using a rotating cutting element. The cutting element has a sharp cutting edge that surrounds a cup-shaped surface and at least one surface of abrasive material. The cup-shaped surface directs the cut material into a tissue chamber. The cutting edge and the cup-shaped surface together are well suited to cut and remove relatively soft tissue from the blood vessel. The abrasive material surface in combination with the cutting element is well suited to abrade and remove hard material from the blood vessel.Type: GrantFiled: May 19, 2017Date of Patent: February 11, 2020Inventors: John Robert Moberg, Alex Yang, Christopher B. Brodeur, William Joseph Whealon, Kee Lee, Phyllis Yuen, Darren Doud

Patent number: 7597775Abstract: The present invention is directed to a green fluoropolymer tube which has a wall thickness of about 250 microns or less, preferably about 200 microns or less, and more preferably about 125 microns or less. With such thinness, the green tube may be formed into a tube of expanded fluoropolymer having a wall thickness of about 250 microns or less, preferably about 200 ?m or less and more preferably about 125 microns or less. Such an expanded fluoropolymer tube is particularly well-suited for use as an endovascular prosthesis, such as a graft, or in a stent-graft, because of its flexibility and strength.Type: GrantFiled: October 30, 2001Date of Patent: October 6, 2009Assignee: Boston Scientific Scimed, Inc.Inventors: David J. Sogard, Jason P. Hill, Timothy S. Girton, Christopher B. Brodeur

Patent number: 7425291Abstract: The present invention provides an apparatus and method for manufacturing polymeric thin-walled tubular members, which are well-suited for use as vascular grafts. The apparatus of the present invention enables extrusion of a tubular member having an extremely thin wall thickness so as to facilitate passage through tortuous vascular passageways. The apparatus achieves uniform wall thickness in a tubular member by establishing and maintaining axial alignment of a ram having a concentrically disposed guide rod therein with a die supported in concentric relation to the guide rod.Type: GrantFiled: September 22, 2004Date of Patent: September 16, 2008Assignee: Scimed Life Systems, Inc.Inventors: James Venditti, Howard Wolek, Alice Wong, David J. Sogard, Jason P. Hill, Timothy S. Girton, Christopher B. Brodeur
