The other, free end portions of the longitudinal members are secured laterally on the base plate after these longitudinal members have crossed the medial aspect of the greater trochanter. This results in a tensioning band construction with at least two restraints based on a plate fixed securely on the proximal lateral femur.Type: GrantFiled: July 16, 2007Date of Patent: July 1, 2014Assignee: SwissMedtechSolutions AGInventors: Kai-Uwe Lorenz, Heiko Durst, Markus Kuster

Patent number: 8764810Abstract: A bone anchoring device includes an anchoring element having a shaft and a head; a receiving part for receiving the head and a rod, the receiving part being formed in one piece and having a top end and a bottom end, a bore extending from the top end to the bottom end, an inner wall defined by the bore, a substantially U-shaped channel adjacent to the top end for receiving the rod and a seat adjacent to the bottom end for accommodating the head; a pressure element; and a spring element having a spring force. The anchoring element is inserted from the top end and is pivotable with respect to the receiving part. The pressure element is movable in the bore so as to be able to fix the anchoring element at an angle with respect to the receiving part by exerting pressure onto the head. The spring element acts between the pressure element and the receiving part and allows the pressure element to be introduced from the top end but withstands against removal of the pressure element through the top end.Type: GrantFiled: September 24, 2010Date of Patent: July 1, 2014Assignee: Biedermann Technologies GmbH & Co. KGInventors: Lutz Biedermann, Wilfried Matthis

Patent number: 8764811Abstract: An apparatus and method of deploying a stent graft having a proximal anchor stent ring includes restraining proximal apexes of the proximal anchor stent ring between a spindle body of a spindle and a control release sleeve of a tapered tip. The control release sleeve is advanced relative to the spindle to release a first proximal apex through an opening in the control release sleeve while the remaining proximal apexes remain restrained by the control release sleeve. The control release sleeve is further advanced relative to the spindle to release the remaining proximal apexes from the control release sleeve. In another example, a stent capture fitting has variable length stent capture fitting arms. As the stent capture fitting is retracted, the proximal apexes of the proximal anchor stent ring are sequentially exposed from and released by the variable length stent capture fitting arms.Type: GrantFiled: April 20, 2010Date of Patent: July 1, 2014Assignee: Medtronic Vascular, Inc.Inventors: Susan Rea Peterson, Brian Glynn

Patent number: 8764812Abstract: A method for deploying an endoluminal vascular prosthesis using a deployment catheter that has at least a main graft portion and a first branch graft portion. The deployment catheter preferably comprises an elongate, flexible catheter body having a proximal end and a distal end, and an outer sheath and an inner core that is axially moveable with respect to the outer sheath. The catheter preferably comprises a main graft restraint that has a main graft release mechanism comprising a main graft sheath and a suture threaded through a plurality of the openings in the main graft sheath. The catheter further comprises at least one branch graft restraint comprising at least one branch graft release mechanism.Type: GrantFiled: January 18, 2013Date of Patent: July 1, 2014Assignee: Endologix, Inc.Inventors: Kevin Mayberry, Trinh Pham, Stefan G. Schreck

Patent number: 8764813Abstract: A gradually self-expanding stent includes a first plurality of stent cells including a first plurality of circumferentially adjacent structural members in mechanical communication with each other. The stent also includes a second plurality of stent cells including a second plurality of circumferentially adjacent structural members in mechanical communication with each other. The circumferentially adjacent structural members of the first and second plurality of stent cells have a compressed configuration and an expanded configuration. A restraining material is attached to each of the circumferentially adjacent structural members defining each of the second plurality of stent cells such that it substantially covers an entirety of each of the second plurality of stent cells in the compressed configuration.Type: GrantFiled: December 23, 2008Date of Patent: July 1, 2014Assignee: Cook Medical Technologies LLCInventors: Alexandra E. Jantzen, Nathaniel A. Irwin, Jeffry S. Melsheimer

Patent number: 8764814Abstract: A medical device for canalization of a tissue comprises a radially expandable and crimpable or collapsible substantially tubular member that has a rear end, a front end, and a pattern of struts or a mesh of wires arranged in-between the rear end and the front end, arranged around an interior of the device. The tubular member has extensions, which are arranged towards the interior of the device in a first state of the device, and towards an exterior of the medical device in a second state of the device, wherein the second state of the medical device is the tubular member turned inside out. During storage, the device is restrained in a delivery catheter in the second state. During delivery the device turns outside in and digs into the tissue to create a channel therein, thus preventing or fixating debris or other matter to spread from the channel.Type: GrantFiled: June 27, 2012Date of Patent: July 1, 2014Assignee: Synergio AGInventor: Jan Otto Solem

Patent number: 8764815Abstract: An intraluminal stent made of a zig-zag or sinusoidal member defining a successive series of struts connected by apex sections and formed into a series of axially displaced hoop members wherein at least one of the hoop members has at least 5 one strut connected to a strut of an adjacent hoop. The connected struts may be connected by spot welding, continuous welding, or suturing, for example, or by a bridging member connected to each strut, and may be spaced along the length of the stent in a pattern to form a connective spine. The number of zigs of the zig-zag member in each hoop member may be varied, as can the zig length. A plurality of 10 connective spines may also be included.Type: GrantFiled: February 28, 2013Date of Patent: July 1, 2014Assignee: Boston Scientific Scimed, Inc.Inventors: David Tseng, Ellen Golds, Bruce A.

Patent number: 8764816Abstract: A stent delivery and deployment system for use primarily with self-expanding stents, incorporating a traction tube extending over the length of the diametrically compacted and constrained stent and everting back over itself, with the outer everted portion of the traction tube preferably extending to the proximal end of the delivery system. A constraining sleeve is provided between the inner, non-everted portion and outer, everted portion of the traction tube, the constraining sheath extending over the length of the constrained stent prior to deployment and diametrically constraining the diametrically compacted self-expanding stent. The application of tension to the proximal end of the traction tube causes the constraining sheath to move in a proximal direction, freeing the constrained stent as it moves and allowing the stent to deploy against the wall of the body conduit within which it is located during the deployment process.Type: GrantFiled: May 7, 2007Date of Patent: July 1, 2014Assignee: W. L. Gore & Associates, Inc.Inventors: Alexander K. Koss, James D. Silverman

Patent number: 8764817Abstract: Disclosed are methods for securing the intersection formed by two or more crossed strands. The intersection defines at least two sections. The practice of the disclosed methods includes bending a securing material, such as a suture or other suitably biocompatible material, through at least two of the sections formed by the intersection, and joining them to secure the intersection. Also disclosed are devices formed by using securing material to secure the intersection of crossed strands of a medical device, such as a woven stent. The secured intersection or intersections of the resultant device enhance the structural integrity of the device, and may serve to eliminate the possible unwinding or release of unsecured, or free, strand ends. Radiopaque materials, in addition to polymers, may be used as securing material.Type: GrantFiled: March 5, 2002Date of Patent: July 1, 2014Assignee: IDEV Technologies, Inc.Inventor: Jeffery J. Sheldon
