Publication number: 20150190255Abstract: An endoprosthesis for deployment within a body passage includes a framework and a metallic film, which can circumferentially surround the framework or be surrounded by the framework. The framework and metallic film can be attached without using a third material, e.g., without sewing. The framework can define a circumferential recess along at least a portion of its length and circumference. The recess accommodates at least a portion of the metallic film therein.Type: ApplicationFiled: March 20, 2015Publication date: July 9, 2015Inventors: Masoud MOLAEI, Beren W. Correa, John Peckham, Alexander Leynov, Stephen Christopher Porter, Robert Z. Obara, Delilah Yin Hui

Patent number: 8685079Abstract: A stent may comprise a plurality of serpentine bands and connectors. A first connector may overlap a second connector when the stent is unexpanded. The first connector may also overlap the second connector in an unexpanded state when the stent is subject to compressive forces in the local area of the connectors, such as when the connectors are located on the inside of a curve. The second connector may be shaped according to a rotation of the first connector about the centroid of the cell between the first connector and the second connector.Type: GrantFiled: October 8, 2012Date of Patent: April 1, 2014Assignee: Boston Scientific Scimed, Inc.Inventors: Alexander Leynov, Delilah Yin Hui, David C. Barry

Patent number: 6860893Abstract: This is an implantable vaso-occlusive device. The device has a complex, three-dimensional structure in a relaxed configuration that may be used in the approximate shape of an anatomical cavity. It may be deployed in the approximate shape of a sphere, an ovoid, a clover, a box-like structure or other distorted spherical shape. The loops forming the relaxed configuration may pass through the interior of the structure. The device is a self-forming shape made from a pre-formed linear vaso-occlusion member. Fibers may be introduced onto the device and affixed to the pre-formed linear member. The constituent member may be also be covered with a fibrous braid. The device is typically introduced through a catheter. The device is passed axially through the catheter sheath and assumes its form upon exiting the catheter without further action. The invention also includes methods of winding the anatomically shaped vaso-occlusive device into appropriately shaped forms and annealing them to form various devices.Type: GrantFiled: October 9, 2001Date of Patent: March 1, 2005Assignee: Boston Scientific SciMed, Inc.Inventors: Michael P. Wallace, Marc-Alan Levine, Delilah Yin Hui, Mary M. Chen, Liem Ho

Patent number: 6660020Abstract: This is an implantable vaso-occlusive coil which is implanted using minimally invasive surgical techniques. It is a complex, helically wound coil made up of a primary helically wound coil which is then wound into a specific secondary shape. The secondary shape is itself a series of helical turns. At least a portion of the turns in the secondary shape form a cylindrical region and adjacent that region on at least one end is a conical region which tapers from a diameter approximating that of the central cylindrical region to a smaller diameter. The device is desirably self-forming upon exit from the distal end of a delivery catheter. Also, the conical tipped vaso-occlusive device may also utilize thrombus-enhancing filamentary material.Type: GrantFiled: November 4, 1999Date of Patent: December 9, 2003Assignee: Target Therapeutics, Inc.Inventors: Michael P. Wallace, Francisco S. Villar, Nga Thi Van, Nestor Aganon, Delilah Yin Hui
