Patent number: 8052741Abstract: A branch prosthesis configured for placement in a branch vessel includes an expandable tubular body portion, an expandable annular flange attached to a proximal end of the body portion, and a sealing sleeve proximally extending from the annular flange. The sealing sleeve is adapted to deform to a generally straight cylindrical hollow shape during implantation. When deployed, the sealing sleeve rolls up to a tightly-wound coil that bears against the annular flange. When used in conjunction with a main prosthesis having a side opening and deployed within in a main vessel, the annular flange of the branch prosthesis engages an outer surface of the main prosthesis around a perimeter of the side opening and the sealing sleeve engages an inner surface of the main prosthesis around the perimeter of the side opening to form a fluid-tight seal between the main prosthesis and the branch prosthesis.Type: GrantFiled: March 23, 2009Date of Patent: November 8, 2011Assignee: Medtronic Vascular, Inc.Inventors: Walter Bruszewski, Masoumeh Mafi, Shahram Shamlou

Publication number: 20110190831Abstract: A balloon catheter can include an actively steerable element for adjusting the configuration of the balloon after placement at a target location. By coupling the actively steerable element to the balloon, any articulation of the actively steerable element will also re-configure the position of the balloon, thereby enabling greater control over procedures that make use of such a balloon catheter. The active steering capability can also enhance the material manipulation capabilities of the balloon catheter, and enable operations and actions that are not possible with a non-steerable balloon catheter.Type: ApplicationFiled: January 29, 2010Publication date: August 4, 2011Applicant: KYPHON SARLInventors: Masoumeh Mafi, Johanah M.

Publication number: 20090264988Abstract: A system and method for delivering a self-expanding stent graft within a segment of a body vessel having a branch vessel extending therefrom. The graft includes one or more self-expanding stents for anchoring the graft to the vessel wall and has a stent-free body portion positionable across the branch vessel. The graft delivery system includes an expandable fenestration support structure at the distal end thereof that is positioned within the graft during delivery. Once the graft has been delivered and expanded into apposition with the vessel wall, the support structure may be expanded therein to press the unsupported body portion of the graft against the branch vessel such that a separate puncture device may be delivered to create a fenestration in the graft for perfusion of the branch vessel. In addition, the expanded fenestration support structure reduces any wrinkles in the graft without a secondary procedure.Type: ApplicationFiled: April 18, 2008Publication date: October 22, 2009Applicant: MEDTRONIC VASCULAR, INC.Inventors: Masoumeh MAFI, Walter BRUSZEWSKI
