Patent number: 8152832Abstract: 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: GrantFiled: January 10, 2007Date of Patent: April 10, 2012Assignee: Boston Scientific Scimed, Inc.Inventors: Mel R. Beulke, Thomas E. Broome, Robert L. Cassell, John M. K. Daniel, Alan D. Eskuri, James G. Hansen, Gary R. Kostur, Douglas B. Molland, Scott R. Smith, Jeffrey H. Vogel, Anthony C. Vrba

Patent number: 7780696Abstract: 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: GrantFiled: December 21, 2005Date of Patent: August 24, 2010Assignee: Boston Scientific Scimed, Inc.Inventors: John M.

Patent number: 7320697Abstract: Apparatus and methods are provided for use in filtering emboli from a vessel, wherein a vascular filter is disposed on a guide wire, the vascular filter having a support hoop disposed from a suspension strut so as to permit lateral eccentric displacement of the support hoop relative to a longitudinal axis of the guide wire. A blood permeable sac is affixed to the support hoop to form a mouth of the blood permeable sac. The support hoop is disposed obliquely relative to the guide wire and is capable of being properly used in a wide range of vessel diameters. The support hoop collapses the mouth of the blood permeable sac during removal of the vascular filter to prevent material from escaping from the sac. A delivery sheath and introducer sheath for use with the vascular filter of the present invention are also provided.Type: GrantFiled: December 8, 2003Date of Patent: January 22, 2008Assignee: Boston Scientific Scimed, Inc.Inventors: Jackson Demond, Marlon C. Moreno, Robert L. Cassell, Peter Hirshman, Eliot T. Kim
