Patent number: 9730715Abstract: A guide wire, for use, for example, in guiding an elongated catheter through an artery or vein of a mammalian body having a stenosis and/or an occlusion therein, includes an elongated conductor having a longitudinal dimension, a proximal end and a distal end. The guide wire further includes an insulator overlying the elongated conductor. The insulator exposes a portion of the longitudinal dimension of the elongated conductor to form an electrode. The elongated conductor is arranged to be connected to a source of high voltage pulses to cause electrical arcs at the electrode that in turn form steam bubbles and shock waves to break the stenosis and/or open the occlusion and permit the guide wire to pass there through. Other embodiments are directed to a system including the guide wire and a method of using the guide wire.Type: GrantFiled: May 8, 2014Date of Patent: August 15, 2017Assignee: SHOCKWAVE MEDICAL, INC.Inventor: John M.

Patent number: 9700448Abstract: Prosthesis delivery devices and methods are provided that enable precise control of prosthesis position during deployment. The catheter for delivering a prosthesis to a treatment site in a body lumen typically carries one or more self-expanding tubular prostheses within a sheath. A radially expandable control member is positionable within the prostheses and has an expanded shape which engages an inner surface of the prostheses to urge the prostheses outwardly against the sheath. The radially expandable control member therefore controls axial position of the prostheses during deployment. Thus one or more prostheses may be deployed at a treatment site precisely. When multiple prostheses are deployed, excessive spacing or overlap between adjacent prostheses is minimized. The prostheses of the present invention are often deployed in stenotic lesions in peripheral arteries as well as coronary arteries and other body lumens.Type: GrantFiled: November 21, 2012Date of Patent: July 11, 2017Assignee: J.W. MEDICAL SYSTEMS LTD.Inventors: David W. Snow, Timothy W. Robinson, Dawn M. Davila, Stuart Lin

Patent number: 9700705Abstract: An inflation device includes a syringe body containing a bore. The bore holds a fluid that is used to inflate a separate device such as a dilation balloon. A plunger assembly slides within the syringe bore and contains a sealing member that forms a fluid tight seal with the syringe body. A shut-off valve is disposed within the distal end of the syringe body. The distal end of the syringe body has a fluid bypass channel fluidically coupled to the aperture of a connector. The shut-off valve has a spring-biased moveable piston with a bypass lumen contained therein, wherein the bypass lumen forms a fluid path between the bore and the fluid bypass channel when the pressure of the fluid is below a threshold value. The fluid path between the bore and the fluid bypass channel is interrupted when the pressure of the fluid is above the threshold value.Type: GrantFiled: July 10, 2015Date of Patent: July 11, 2017Assignee: ENTELLUS MEDICAL, INC.Inventors: Paul R.

Patent number: 9694108Abstract: The present invention is directed to a device that permits a permanent aperture to be formed in a wall, or other partition, of an implantable medical device. The present invention maintains the continuity and fluid-retaining properties of the implantable medical device by providing a breachable barrier material fully covering an opening delimited by a deformable framework. The invention is accessed with conventional interventional surgical instruments that disrupt and displace the barrier material. Following disruption of the barrier material, the opening is enlarged with surgical instruments to form a permanent framed aperture in the wall of the implantable medical device. The permanent framed aperture provides fluid communication across the wall of the implantable medical device.Type: GrantFiled: July 31, 2013Date of Patent: July 4, 2017Assignee: W. L.

Patent number: 9629654Abstract: A thrombus removal apparatus (10) includes a catheter (12) having at its distal end (14) a solenoid coil section (16) within which there is disposed a piercing element (20) made of electromagnetic material. Within the solenoid coil section (16) there is provided a solenoid coil (26) which can be powered to generate an electromagnetic field which causes the piercing element (20) to reciprocate into and out of the coil section (16), in practice to pierce into and fragment a thrombus disposed in a patient's vessel. An aspiration unit may be provided for aspirating thrombus fragments into the assembly (10) for removal from the patient's vasculature. The apparatus (10) is able to remove dense thrombus material from within a patient, which cannot be otherwise removed by means of thrombolytic agents.Type: GrantFiled: March 6, 2013Date of Patent: April 25, 2017Assignee: Cook Medical Technologies LLCInventor: Torben Peter Andersen

Patent number: 9623214Abstract: A trans-endoscopic hydraulic balloon dilation apparatus includes a fluid reservoir containing a hydraulic fluid. A shaft has a lumen in fluid communication with a leading end of the fluid reservoir. A balloon is mounted on the shaft and an opening in the shaft enables hydraulic fluid to flow through the opening into or from the balloon. A piston secured to a leading end of a piston rod is slideably positioned within a lumen of the fluid reservoir. A hub secured to a trailing end of the fluid reservoir is centrally apertured to accommodate the piston rod so that a trailing end of the piston rod is external to the fluid reservoir. Displacement of the piston rod in a trailing-to-leading direction causes expansion of the balloon. Displacement of the piston rod in a leading-to-trailing direction causes deflation of the balloon. The piston can be locked into any position.Type: GrantFiled: August 5, 2015Date of Patent: April 18, 2017Assignee: University of South FloridaInventor: James Stephen Barthel
