Patent number: 8535371Abstract: A method of positioning a tubular element inside a main blood vessel of a person. The tubular element has a main tube with one or more side openings and a transport wire extending through each side opening. A fixator being positioned in each branch vessel and the corresponding guide wire being attached to the corresponding transport wire, whereby re-routing of the guide wire is performed by pulling the transport wire to have the guide wire extend from the fixator through the corresponding side opening and to the outside of the person. This re-routed guide wire may be used for positioning the tubular element or guiding additional elements from the tubular element and into the branch vessel.Type: GrantFiled: November 15, 2010Date of Patent: September 17, 2013Assignee: Endovascular Development ABInventor: Krister Liungman

Publication number: 20130226280Abstract: A device (100) for treating a stiffened blood vessel comprises a self-supporting, surgically implantable, elongate casing (101) adapted to extend about and restrain a stiffened portion (2) of the blood vessel. The casing (101) defines an elongate cavity (103) for receipt of the stiffened portion (2) of the blood vessel. The cavity (103) has a transverse cross-section with an aspect ratio of greater than one in an unloaded state. The casing (103) is configured such that, upon application of increasing pressure to the casing (101) from within said cavity (103), the casing (103) elastically deforms such that the aspect ratio decreases towards one and the area of the cross-section increases.Type: ApplicationFiled: August 24, 2012Publication date: August 29, 2013Applicant: Aortic Wrap Pty LtdInventor: Michael O'Rourke

Patent number: 8518103Abstract: A catheter assembly includes an elongate main catheter branch and an elongate side catheter branch. The main catheter branch includes an arc shape and an inflatable balloon extending along a portion of the arc. The side catheter branch extends along the main catheter branch within a plane of the curvature of the arc of the main catheter branch. A stent can be positioned along the inflatable balloon. The stent includes a lateral branch opening through which the side catheter branch extends.Type: GrantFiled: June 4, 2007Date of Patent: August 27, 2013Assignee: Boston Scientific Scimed, Inc.Inventors: Matt Heidner, Karen Turner

Publication number: 20130211505Abstract: This disclosure is related to devices and related methods for isolating a treatment region in a human body from fluid pressure. In various embodiments, an implantable device for isolating a treatment region in a human body from fluid pressure comprises a first elongated segment, and a second elongated segment, and one or more branch segments in fluid communication with one of the first elongated segment and the second elongated segment. The elongated segments have a combined cross section that is substantially conformable to an intraluminal cross section of a body lumen into which they are implanted. A method of installing an implantable medical device into the body of a patient comprises deploying a first elongated segment, deploying a second elongated segment, and deploying one or more branch segments in a target region of a vasculature.Type: ApplicationFiled: August 10, 2012Publication date: August 15, 2013Inventor: Aaron Robison

Publication number: 20130211506Abstract: A device for treating disease along a main vessel and at least one branch vessel extending from the main vessel includes a branch member for deployment in the branch vessel, the branch member having a branch lumen; and a main body for deployment in the main vessel. The main body has a generally tubular wall extending generally longitudinally between opposite first and second ends. The wall has an internal surface defining a main lumen and an opposite outer surface. The wall has a recessed portion that is recessed relative to the outer surface of the wall and positioned between the first and second ends of the main body. The main body has an opening formed in the recessed portion of the wall for receiving the branch member therethrough such that the branch lumen is in fluid communication with the main lumen.Type: ApplicationFiled: August 13, 2012Publication date: August 15, 2013Inventors: Michael D. Dake, Joshua J. Lovekamp, Michael C. Nilson, Edward E. Shaw
