Patent number: 7309318Abstract: The present invention relates generally to guidewires with a high level of torquability, flexibility, and elasticity. In an embodiment, a guidewire comprises an elongate shaft having an outside diameter. The shaft may include a filler and a polymeric matrix, wherein the filler includes a plurality of wires, wherein the matrix substantially surrounds the filler, and wherein the outside diameter of the shaft is sized appropriately for being disposed within a lumen of an intravascular catheter.Type: GrantFiled: September 18, 2002Date of Patent: December 18, 2007Assignee: Boston Scientific Scimed, Inc.Inventors: Robert Cassell, Jeffrey H. Vogel

Publication number: 20070123913Abstract: Anchoring mechanisms for releasably securing an intravascular device along an elongated member such as a guidewire or catheter. The anchoring mechanism may include an object that can be actuated between an unlocked position and a locked position. In the unlocked position, the anchoring mechanism is slidably and rotationally disposed about the elongated member. In the locked position, the anchoring mechanism is releasably secured to the elongated member, preventing movement thereon. A placement mechanism such as a tubular member can be utilized to actuate the anchoring mechanism between the unlocked and locked positions.Type: ApplicationFiled: January 10, 2007Publication date: May 31, 2007Applicant: BOSTON SCIENTIFIC SCIMED, INC.Inventors: Mel Beulke, Thomas Broome, Robert Cassell, John Daniel, Alan Eskuri, James Hansen, Gary Kostur, Douglas Molland, Scott Smith, Jeffrey Vogel, Anthony Vrba

Publication number: 20060100662Abstract: An emboli capturing system captures emboli in a body lumen. A first elongate member has a proximal end and a distal end. An expandable emboli capturing device is mounted proximate the distal end of the first elongate member, and is movable between a radially expanded position and a radially contracted position. When in the expanded position, the emboli capturing device forms a basket with a proximally opening mouth. A second elongate member has a proximal and a distal end with a lumen extending therebetween. The lumen is sized to slidably receive a portion of the first elongate member. An expandable delivery device is mounted to the distal end of the second elongate member and is movable from a radially retracted position to a radially expanded position. The delivery device has a receiving end configured to receive the emboli capturing device, and retains at least the mouth of the emboli capturing device in a radially retracted position.Type: ApplicationFiled: December 21, 2005Publication date: May 11, 2006Inventors: John Daniel, Thomas Broome, David Holtan, Robert Cassell, Daniel Adams
