  • Patent number: 10149677
    Abstract: A vessel access and closure device places a running suture in the wall of a blood vessel using a rotating helical suture needle that carries the suture along a helical path passing through the vessel wall, then reverses rotation to release a suture anchor attached to the distal end of the suture. A loose helical coil of suture is left behind as the helical suture needle withdraws. The device is withdrawn and replaced with a vessel dilator and an introducer sheath that opens up a larger access opening into the blood vessel and creates a pathway that passes though the helical coil of suture for introducing an interventional device into the blood vessel. After the interventional procedure is completed, the interventional device and the introducer sheath are withdrawn and the running suture is tightened and secured with a suture lock to close the access opening into the vessel.

  • Patent number: 10123800
    Abstract: 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.

  • Publication number: 20170312499
    Abstract: 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.
