Patent number: 10123800Abstract: Apparatus for closing a surgical incision comprise a base having left and right panels, a force distribution structure coupled to each panel, and a closure component which releasably attaches to the force distribution structure to draw the inner edges of the panels together in order to close adhered tissue edges. The force distribution structures allow the inner edges of the panels to expand while restraining expansion of the outer edges of the panels and limiting elongation of the lateral dimension of the panels. The incision closure appliance may be placed on skin or other tissue prior to forming the incision to be available to close said incision at the end of the surgical procedure.Type: GrantFiled: October 31, 2012Date of Patent: November 13, 2018Assignee: ZipLine Medical, Inc.Inventors: Amir Belson, Eric Storne, Eric T. Johnson, Robert R. Ragland, Phillip C. Burke, Luke Clauson

Publication number: 20170312499Abstract: Devices, systems and methods are provided for accessing and treating anatomies associated with a variety of conditions while minimizing possible complications and side effects. This is achieved by directly neuromodulating a target anatomy associated with the condition while minimizing or excluding undesired neuromodulation of other anatomies. Typically, this involves stimulating portions of neural tissue of the central nervous system, wherein the central nervous system includes the spinal cord and the pairs of nerves along the spinal cord which are known as spinal nerves. In particular, some embodiments of the present invention are used to selectively stimulate portions of the spinal nerves, particularly one or more dorsal root ganglions (DRGs), to treat chronic pain while causing minimal deleterious side effects such as undesired motor responses.Type: ApplicationFiled: November 16, 2015Publication date: November 2, 2017Inventors: Fred I. Linker, Daniel M. Brounstein, Albert G. Burdulis, Eric T. Johnson, Phillip C. Burke, Evan S. VandenBrink, Eric J. Grigsby, Henry L.S. Tan

Patent number: 5497920Abstract: A sports bottle includes a generally cylindrical hollow vessel having a liquid chamber formed therein and a closed end bottom. The generally cylindrical vessel further defines a reduced diameter neck portion and an upper chamber terminating in an upwardly facing mouth. The upper chamber supports a porous antisplash element preferably formed of a coarse porous foam material plastic or the like. An elongated tubular straw extends from the bottom surface within the vessel upwardly through the neck portion and through the antisplash element and beyond the mouth to form an upwardly extending end which receives a flexible mouth tube which is preferably curved toward the user when the sports bottle is secured to a conventional bicycle. In alternate embodiments, the antisplash element within the upper chamber of the vessel is formed of a plurality of tubular members defining passages therethrough and grouped together to form a generally cylindrical multipassage combination.Type: GrantFiled: October 14, 1993Date of Patent: March 12, 1996Assignee: Michael D. MoellerInventors: Michael D. Moeller, Phillip C. Burke

Patent number: 5485042Abstract: The invention provides a motor drive unit for use in conjunction with an atherectomy device which limits the torque exerted on a drive cable for rotating a cutting blade in the device. In a preferred embodiment, a motor drive unit includes a motor having a shaft coupled to the drive cable for rotating the cutting blade, a power supply coupled to the motor and a switch for selectively connecting the power supply to the motor. A torque control circuit connected to the power supply and the motor controls the torque exerted by the motor when the switch is closed, whereby the current to the motor is continuously increased from zero to a start-up level, the start-up level being the minimum current sufficient to turn the cutting blade.Type: GrantFiled: October 6, 1994Date of Patent: January 16, 1996Assignee: Devices for Vascular Intervention, Inc.Inventor: Phillip C.
