Patent number: 7479155Abstract: A release assembly is provided to aid the reversible and repositionable deployment of a defect occluder. The release assembly includes an occluder tether having a distal portion comprising at least one suture loop, and a snare structure having a distal portion comprising a snare element. The at least one suture loop is receivable through at least a portion of the defect occluder, and reversibly looped over an anchor element so as to permit reversible collapse the defect occluder for selective ingress and egress from a delivery catheter. The snare element is reversibly engageable with the anchor element so as to reversibly retain the at least one suture loop upon the anchor element, and thereby hold the defect occluder in a posture for reversible free-floating tethered deployment in a defect while being observable in a final position prior to release.Type: GrantFiled: August 26, 2002Date of Patent: January 20, 2009Assignee: EV3 Endovascular, Inc.Inventors: John P. Gainor, Brian L. Dukart, Darren L. Wegner

Patent number: 7445626Abstract: Systems for suturing a tissue layer having two sides with a suture be releasably retaining at least a portion of the suture in a stationary position on one side of the tissue layer. The portion of the suture is retrieved through the tissue layer from the opposite side whereby the suture is drawn from one side to the opposite side. Systems for suturing the wall of a tubular graft having two sides is also provided using a suture by releasably retaining at least a portion of the suture on one side of the wall. the portion of the length of suture is retrieved through the wall of the graft to the opposite side of the wall.Type: GrantFiled: December 16, 2003Date of Patent: November 4, 2008Assignee: Abbott LaboratoriesInventors: Ronald W. Songer, James W. Vetter, Enrique J. Klein, Bernard A. Andreas, Michael Barrett, Mark J. Foley, Brian Gore, Lewis Isbell, T. Daniel Gross, Tomoaki Hinohara

Patent number: 7442199Abstract: A one-hand operated acupuncture dispensing system to administer acupuncture treatment at an acupoint point is described. The system includes an acupuncture needle, a clip and a guide tube to house the needle and the clip for securing and releasing the needle inside the guide tube. The tube prevents the clip from separation from the tube after the needle is dispensed. The clip is shaped to allow the acupuncture needle to exit the guide tube at an angle. The clip and/or guide tube can provide color coding. An alternate to the system includes a cap that joins with a guide tube housing an acupuncture needle. This alternate system also includes a clip that secures and releases the needle. In this alternate system, the cap, as well as the clip and/or guide tube can provide color coding.Type: GrantFiled: December 27, 2005Date of Patent: October 28, 2008Inventor: Hong Dar Teng

Patent number: 7438720Abstract: A stent delivery system for treating lesions is provided. The system is suitable for treatment of bifurcation lesions, has a low profile and provides substantially predictable translational and rotational positioning. In one embodiment, the system includes a fixed wire balloon catheter and a partially attached guidewire lumen, wherein the guidewire lumen is attached to the catheter at a crotch point. The location of the crotch point is predetermined so as to provide substantially predictable positioning. Several embodiments of the system are described for various types of lesions and vessel configurations.Type: GrantFiled: March 3, 2005Date of Patent: October 21, 2008Assignee: Y Med Inc.Inventor: Yoav Shaked

Patent number: 7419495Abstract: A trigger lockout device for a clip applying instrument. The lockout device includes a displaceable slider actuable by squeezing a trigger slidable in first and second directions a longitudinal axial direction within the barrel, and a block disposed within the barrel. When a first number of clips have not been applied and when the trigger is squeezed, the slider slidably engages and displaces the block and slides along a path in the axial direction to retrieve a clip of the first number of clips, and to insert the clip into the pair of jaws, and when a second number or none of the clips have not been applied, the slider engages the block to substantially prevent the slider from sliding along the path in at least one of the first or second directions such that the triggery cannot be unsqueezed.Type: GrantFiled: August 25, 2005Date of Patent: September 2, 2008Assignee: Microline Pentax Inc.Inventors: Pavel Menn, Emmanuel Manetakis, Peter Aliski

Patent number: 7410495Abstract: A medical closure screen device for a separation of first and second tissue portions is provided, which includes a mesh screen comprising tubular vertical risers, vertical strands with barbed filaments, and horizontal spacers connecting the risers and strands in a grid-like configuration. An optional perimeter member partly surrounds the screen and can comprise a perimeter tube fluidically coupled with the vertical risers to form a tubing assembly. Various input/output devices can optionally be connected to the perimeter tube ends for irrigating and/or draining the separation according to methodologies of the present invention. Separation closure, irrigation and drainage methodologies are disclosed utilizing various combinations of closure screens, tubing, sutures, fluid transfer elements and gradient force sources. The use of mechanical forces associated with barbed strands for repositionably securing separated tissues together is disclosed.Type: GrantFiled: April 11, 2005Date of Patent: August 12, 2008Assignee: KCI Licensing, Inc.Inventor: David S. Zamierowski
