Patent number: 8603153Abstract: A system and method employs collar stents to implant an endoluminal device, such as a stent-graft, in a lumen. The system comprises at least one collar stent adapted to precondition a portion of the lumen for anchoring an endoluminal device having at least a portion adapted to be deployed radially within the collar stent. The method comprises first deploying one or more collar stents, and then deploying the endoluminal device radially within the one or more collar stents. In various embodiments, the collar stent may be radiopaque, may have inwardly protruding barbs for engaging the endoluminal device, and may have a region having a relatively low percentage of open area for bridging a portion of the main lumen having an intersecting lumen. The preconditioning step of implanting the collar stent may change the morphology of the lumen to more favorable morphology, such as from a non-circumferential geometry to a circumferential geometry.Type: GrantFiled: February 28, 2005Date of Patent: December 10, 2013Assignee: Lifeshield Sciences, LLCInventor: Patrick A.

Publication number: 20120101525Abstract: A device for sealing an opening in a vessel includes an anchor attached to a suture. The anchor is inserted through the opening into the vessel, and the suture pulls the anchor against the vessel wall, forming a seal. A plug is inserted over the suture and is axially compressed toward the anchor, locking the elements in place. The suture is braided or woven outside of the anchor so that it may be stored and handled easily, and is unbraided, unwoven and/or untangled at its distal end inside the anchor, so that individual filaments within the suture may extend laterally within the anchor. The laterally extending filaments subtend a larger footprint within the anchor than a comparable footprint if the suture were to remain braided or tied into a knot within the anchor, which may more effectively distribute the retaining forces within the anchor.Type: ApplicationFiled: October 21, 2011Publication date: April 26, 2012Applicant: BOSTON SCIENTIFIC SCIMED, INC.Inventors: Mark L. Jenson, Jason P. Hill, James Q. Feng, David J. Sogard, Robert W. Warner, Patrick A. Haverkost

Publication number: 20120029510Abstract: A catheter includes a flexible shaft having a distal end dimensioned for deployment within a patient's renal artery. A number of elongated resilient members are mounted along a longitudinal length of the distal end of the shaft, and are extensible radially from the shaft at regions defined between longitudinally spaced-apart engagement locations. One or more electrodes are mounted on each of the resilient members at the radially extensible regions. A number of conductors are electrically coupled to the electrodes and extend along the shaft of the catheter. The elongated resilient members are collapsible when encompassed within a lumen of an outer sheath and extensible radially outward from the shaft at the regions defined between the longitudinally spaced-apart engagement locations when the catheter and the resilient members are axially extended beyond the distal tip of the sheath. RF energy is delivered to the electrodes for ablating perivascular renal nerves.Type: ApplicationFiled: July 18, 2011Publication date: February 2, 2012Inventor: Patrick A. Haverkost
