  • Patent number: 9554927
    Abstract: A stent includes a central portion of helically wound undulations formed of struts, cylindrical end portions, and transition zones between the helical portion and the cylindrical portions. According to a first aspect of the invention, the torsional flexibility of the stent is maximized by having bridges connecting adjacent winding be interrupted by the maximum possible number of undulations. In one embodiment, each winding includes nineteen undulations around the circumference, bridges are provided every five undulations. According to a second aspect of the invention, uniform opening of the transition zone is achieved by altering the width, and thereby the flexibility, of a series of struts in accordance with their lengths. Specifically, the long transition zone struts are made wider.

  • Patent number: 9539005
    Abstract: A deployment device and an associated surgical fastener as well as their methods of use are disclosed. In one embodiment, the deployment device includes a restraining mechanism constructed and arranged to temporarily limiting movement of a surgical fastener back span. The surgical fastener includes two legs extending in a distal direction from opposing ends of the back span. The legs are in a first closed position with a first shape. The deployment device also includes a spreader configured and arranged to engage the legs of the surgical fastener in the first closed position. When the spreader is moved in a distal direction relative to the back span, the spreader spreads the legs of the surgical fastener from the first closed position to a second open position as the back span is limited from distally moving by the restraining mechanism.

  • Publication number: 20170000481
    Abstract: Surgical instruments and their methods of use are described. In one embodiment, a surgical instrument includes a power transmission including a trigger and a fastener driver operatively coupled to the trigger. Actuation of the trigger from a first configuration to a second configuration moves the fastener driver between at least a first position and a second position. Additionally, an actuation lockout system operatively associated with the power transmission is moveable between a locked configuration and an unlocked configuration. The actuation lockout system prevents movement of the fastener driver from the first position to the second position when the actuation lockout system is in the locked configuration. Actuation of the trigger from the first configuration towards the second configuration moves the actuation lockout system from the locked configuration to the unlocked configuration.

  • Patent number: 9526440
    Abstract: An integrated catheter placement system for accurately placing a catheter within a patient's vasculature is disclosed. In one embodiment, the integrated system comprises a system console, a tip location sensor unit for temporary placement on the patient's chest, and an ultrasound probe. The tip location sensor senses a field produced by a stylet disposed in a lumen of the catheter when the catheter is disposed in the vasculature. The ultrasound probe ultrasonically images a portion of the vasculature prior to introduction of the catheter. ECG signal-based catheter tip guidance is included to enable guidance of the catheter tip to a desired position with respect to a node of the patient's heart. The stylet includes an electromagnetic coil that can be operably connected to the sensor unit and/or console through a sterile barrier without compromising the barrier. The stylet can also be wirelessly connected to the sensor unit and/or console.

  • Patent number: 9504549
    Abstract: Implantable prostheses for repairing soft tissue defects near an anatomical tube and methods for their manufacture are described. Exemplary prostheses may be implanted at a soft tissue repair site, for example, in treating an inguinal hernia. An implantable prosthesis may include a patch made up of two co-knit fabric layers, and a passageway for receiving an anatomical cord extending through the fabric layers. The passageway is configured through the first fabric layer so as to minimize the prospects of the cord-like structure contacting the portion of the second fabric layer defining the passageway therethrough. The passageway through the first fabric layer may include a barrier.

  • Patent number: 9498318
    Abstract: A removable blood clot filter includes a number of locator members and anchor members disposed radially and extending angularly downward from a hub. The locator members include a number of linear portions having distinct axes configured to place a tip portion approximately parallel to the walls of a blood vessel when implanted and to apply sufficient force to the vessel walls to position the filter near the vessel centerline. The anchor members each include a hook configured to penetrate the vessel wall to prevent longitudinal movement due to blood flow. The hooks may have a cross section sized to allow for a larger radius of curvature under strain so that the filter can be removed without damaging the vessel wall.

  • Patent number: 9468513
    Abstract: A blood clot filter includes a number of locator members and anchor members, each of the members tipped with a retainer encompassed within bio-resorbable cover material. Upon delivery into a blood vessel, the locator and anchor members position the filter near the vessel centerline. After a period of time, the bio-resorbable cover material resorbs, allowing the retainer on the members to penetrate and attach to the vessel wall. A method of implanting the filter includes delivering the filter into a blood vessel and allowing the bio-resorbable cover material to resorb so retainers on the members can engage the vessel walls.
