Patent number: 8870739Abstract: The present invention is a conduit device designed to be placed within a wall of a heart, such as through a prepared opening or hole in the heart wall. The conduit is hollow and extends to form a sleeve over a portion of the heart pump, such as a VAD, which traverses the heart wall and enters a chamber of the heart. The conduit provides for a simplified and noninvasive approach to removal and/or replacement of the heart pump.Type: GrantFiled: August 5, 2011Date of Patent: October 28, 2014Assignee: HeartWare, Inc.Inventors: Jeffrey A. LaRose, Douglas E. Godshall

Patent number: 6945950Abstract: A ureteral stent for assisting movement of urine along a patient's ureter and into the patient's bladder. The stent includes an elongated tubular segment extending toward the bladder from a kidney end region for placement in the renal cavity to a bladder end region. A central lumen connects at least one opening at the first end region to at least one opening in the bladder end region. Thin flexible tail(s) are attached to the bladder end region of the tubular segment at a point outside the bladder so as to receive urine from the opening in the bladder end region and to transport urine from there across the ureter/bladder junction and into the bladder. The tails include an elongated external urine-transport surface configured to transport urine. The transporting surface(s) are configured to extend along at least part of the ureter, across the ureter/bladder junction, and into the bladder.Type: GrantFiled: September 12, 2003Date of Patent: September 20, 2005Assignee: Boston Scientific SciMed, Inc.Inventors: Ralph V. Clayman, Alyssa J. Dassa, Christopher Fishbein, Douglas E. Godshall, Willet F. Whitemore, III

Patent number: 6368356Abstract: The invention provides a means of boosting the mechanical performance of shaped shaped medical devices comprising polymer hydrogels, such as stents, so that they may be more easily inserted into or removed from the body. In one aspect, the invention provides shaped medical devices having increased mechanical strength and comprising both ionic and covalent crosslinks. In another aspect, the invention provides a shaped medical device having a heterogeneous polymer composition and a variable dissolution or degradation rate along its length. The shaped medical devices according to the present invention retain their shape and stiffness during insertion into the body and can swell and soften inside the body to enhance patient comfort.Type: GrantFiled: February 25, 2000Date of Patent: April 9, 2002Assignee: SciMed Life Systems, Inc.Inventors: Sheng Ping Zhong, Arthur R. Madenjian, Douglas E. Godshall, John M. Ronan, Samuel A. Thompson

Patent number: 5681274Abstract: A variable length ureteral stent assembly. A central catheter tube forms a ureter stent with a retention structure for anchoring the stent in the ureter particularly within the bladder and kidney. The catheter tube is formed of a shape memory material and at least one of the retention structures includes a end portion of the catheter wrapped spirally into a multiple-turn planar coil having an axis that is transverse to the plane of the structure. The retention structure can then be partially unwound while still providing an anchoring function. Partially unwinding increases the length of an intermediate section of the ureteral stent.Type: GrantFiled: March 31, 1995Date of Patent: October 28, 1997Assignee: Boston Scientific CorporationInventors: D.
