Patent number: 9808277Abstract: A device suitable for removing material from a living being is provided, featuring at least an aspiration pump, powered by a motor. The aspiration pump and any optional infusate pump preferably feature a helical pumping mechanism, and operate at a high rate of rotation, thereby ensuring adequate pumping performance and flexibility. The helical pumping mechanism may be a helical coiled wire about a central core tube. The helical coil wire, whether together with, or independent of, the core tube, may be rotated to cause a pumping action. Additionally, a narrow crossing profile is maintained, ensuring that the device may reach more tortuous regions of the vasculature. In one embodiment, the system comprises a wire-guided mono-rail catheter with a working head mounted on a flexible portion of the catheter that can laterally displace away from the guide wire to facilitate thrombus removal.Type: GrantFiled: December 5, 2014Date of Patent: November 7, 2017Assignee: The Spectranetics CorporationInventors: John E. Nash, Greg Walters, Dennis M. Sauro, Mark Eberhardt, William T. Fisher, Douglas G. Evans

Patent number: 9114408Abstract: Centrifuges are useful to, among other things, remove red blood cells from whole blood and retain platelets and other factors in a reduced volume of plasma. Platelet rich plasma (PRP) and or platelet poor plasma (PPP) can be obtained rapidly and is ready for immediate injection into the host. Embodiments may include valves, operated manually or automatically, to open ports that discharge the excess red blood cells and the excess plasma into separate receivers while retaining the platelets and other factors in the centrifuge chamber. High speeds used allow simple and small embodiments to be used at the patient's side during surgical procedures. The embodiments can also be used for the separation of liquids or slurries in other fields such as, for example, the separation of pigments or lubricants.Type: GrantFiled: June 19, 2014Date of Patent: August 25, 2015Assignee: Kensey Nash CorporationInventors: John E. Nash, William T. Fisher

Publication number: 20150218506Abstract: A centrifuge device is provided for the sizing and separation of constituents of a biologic mixture, e.g., adipose tissue. The device provides for the mechanical breaking down of the fibrous structure in the tissue by centrifugation causing the tissue to pass through a mesh element, or a sizing helix, or an extrusion element, whereupon the material is reduced to a slurry. This processed material may then be separated by centrifugation into its constituents, in order to harvest the fraction containing the multipotent cells. These multipotent cells may be utilized for various medical procedures to stimulate healing and tissue regeneration.Type: ApplicationFiled: January 30, 2015Publication date: August 6, 2015Inventors: JOHN E. NASH, WILLIAM T. FISHER, GINO BRADICA

Patent number: 8911406Abstract: A guide wire exchange system including an elongate, flexible, guide wire exchange catheter capable exchanging one guide wire for another in a safe, efficient, and secured manner, where a primary guide wire, after having been advanced through the body, is to be replaced with a secondary guide wire that is to be securely advanced through the body to the target site by the advancement of the exchange catheter over the path of the primary wire. The exchange catheter may include a securement element in order to releasably secure at least one guide wire to the exchange catheter at or near the distal end of the exchange catheter. Once secured, both the exchange catheter and the secured guide wire(s) may be advanced or retracted in a synchronous manner, without the possibility of divergence at the distal ends of the secured components as they are being manipulated by an operator.Type: GrantFiled: July 12, 2006Date of Patent: December 16, 2014Assignee: Kensey Nash CorporationInventors: Douglas G.

Patent number: 8721626Abstract: In an embodiment, the invention provides a catheter suitable for use in performing a procedure within a vessel, lumen or organ of a living having a distal end which is steerable, such as upon the application of compression. The catheter may be of the over the wire type, or alternatively may be a rapid exchange catheter. The catheter may provide for a rotating element which may be used to open a clogged vessel, or alternatively to provide information about adjacent tissues, such as may be generated by imaging or guiding arrangements using tissue detection systems known in the art, e.g., ultrasound, optical coherence reflectometry, etc. For rapid exchange catheters having a rotating element, there is provided an offset drive assembly to allow the rotary force to be directed from alongside the guidewire to a location coaxial to and over the guidewire.Type: GrantFiled: March 8, 2010Date of Patent: May 13, 2014Assignee: Kensey Nash CorporationInventors: William T.

Patent number: 8683895Abstract: There is provided a device for the delivery of surgical fasteners. The device improves the penetration of the fasteners and reduces the effort required for a surgeon to hold opposing pressure in order to deploy the fastener. The device comprises a lever in mechanical cooperation with a resilient element for storing energy; a drive mechanism which cooperates with at least one surgical fastener; and a release mechanism for rapidly releasing stored energy from the resilient element to the drive mechanism. In certain embodiments, at least partial depression of the lever stores energy in the resilient element while release of the lever from the at least partial depressed position does not release the stored energy from the resilient element. Additionally, the drive mechanism converts stored energy from the resilient element upon activation of the release mechanism to deliver the at least one surgical fastener.Type: GrantFiled: February 23, 2010Date of Patent: April 1, 2014Assignee: Kensey Nash CorporationInventor: John E.
