Patent number: 8118774Abstract: Disclosed herein are elongate flexible medical devices which are capable of axial elongation through the mechanism of eversion or toposcopic expansion. In general, this may be accomplished by providing a flexible tubular device having a proximal end and a distal end. Retraction of the distal end in a proximal direction through the tubular body inverts the tube upon itself, causing an axial shortening of the overall length of the device. The original length of the device can be restored by coupling a pressurized media to the proximal end of the sleeve. If the distal end of the sleeve is temporarily restricted or closed, the pressurized media causes the distal end of the sleeve to travel distally until the full length of the sleeve has been restored.Type: GrantFiled: September 25, 2007Date of Patent: February 21, 2012Assignee: ValenTx, Inc.Inventors: Mitchell Dann, Greg Fluet, James Wright

Patent number: 8118775Abstract: A catheter for diagnosing or treating the vessels found within a body or body space includes a center strut that is bonded, preferably thermally, along its longitudinal axis with the thermoplastic tubular member within which it is housed. The tubular member preferably has three layers: an inner layer, a braided layer and an outer layer. The composite catheter is made using a process in which two half-cylinder shaped mandrels are placed on each side of the center strut while the strut is heated in order to cause the thermal bonding. The bonded center strut provides in-plane deflection and improved transfer of torque to the tip of the catheter.Type: GrantFiled: September 9, 2008Date of Patent: February 21, 2012Assignee: Biosense Webster, Inc.Inventors: Debby Grunewald, Irma Hill, Thomas Selkee

Patent number: 8088150Abstract: A Quincke tipped introducer needle contains two shafts with lumens, one recessed, both connected by a slit for housing a U- or V-shaped disc shunt. The recessed shaft minimizes the penetration size of the introducer needle for insertion into a narrow and nerve laden space adjacent to a degenerated intervertebral disc. The longitudinal slit connecting the two lumens allows passage of the distal portion of the U-shaped disc shunt through the introducer needle, to be delivered into the intervertebral disc. Pain emitting from the avascular disc is extremely difficult to treat due to lack of penetration or permeability of drug. The lumens of the introducer needle are also used to retain a peri-shunt injectable into the disc shunt for delivery into the painful disc. The peri-shunt injectable can be an analgesic, narcotic, anti-inflammatory drug, antibiotic, anticonvulsant, antidepressant, buffer agent or alkaline agent to alleviate pain.Type: GrantFiled: February 4, 2009Date of Patent: January 3, 2012Assignee: Aleeva Medical Inc.Inventors: Jeffrey E. Yeung, Teresa T. Yeung

Patent number: 8070723Abstract: The fluid infusion system is disclosed that includes a pump housing that has a reservoir cavity and is designed to be pocketable. The reservoir cavity has a rim and helical coupling features formed on an interior face of the reservoir cavity. The fluid infusion system further has a reservoir that is removable from the reservoir cavity and the reservoir also has an open end. A removable cap coupled to the pump housing is also included in the fluid infusion system. The cap has corresponding coupling features, an exterior surface and a tab. The corresponding coupling features are defined to couple the cap to the pump housing while the tab is defined as a ridge that extends away from the exterior surface. The tab further has a port to accommodate fluid flow from the reservoir where the port defines an axis of rotation such that torque applied to the tab about the axis of rotation disengages the coupling between the cap and the pump housing.Type: GrantFiled: December 31, 2009Date of Patent: December 6, 2011Assignee: Medtronic Minimed, Inc.Inventors: Afshin Bazargan, Sheldon B. Moberg, Kevin Lee Bokelman, Daniel S. Kline, Steven Masterson

Patent number: 8070729Abstract: Systems and methods for treating a vessel include devices having a main elongated element with a balloon at its distal end, an auxiliary elongated element wherein a distal end of the auxiliary elongated element is proximal to the balloon, and a core wire having a internal core wire portion and an external core wire portion, wherein the external core wire portion is external to the balloon. In some embodiments, a distal connecting element is attached to the distal end of the balloon. In some embodiments, the distal connecting element is positioned at a rotational distance from the auxiliary elongated element. In some embodiments, the balloon is a fixed wire balloon. Inflation of the balloon causes guidewires positioned within the device and external core wires to be pushed up against the lesion, providing a focused force for cracking the lesion.Type: GrantFiled: July 15, 2009Date of Patent: December 6, 2011Assignee: YMED, Inc.Inventors: Ronald J.
