  • Anchoring system for a catheter
    Patent number: 9642987
    Abstract: An anchoring system secures a catheter to the body of a patient and arrests axial movement of the catheter without meaningfully impairing fluid flow through the catheter. The anchoring system includes an anchor pad that adheres to the patient's skin and supports a retainer. The retainer includes interengaging structure that moves the retainer between an open and a closed position. When in the open position, the retainer can receive a portion of the catheter and be subsequently moved to the closed position. Advantageously, the interengaging structure allows the retainer to receive catheters of various sizes. The retainer may further include one or more retention mechanisms to further inhibit axial movement of the catheter relative to the retainer when the catheter is secured therein. The anchoring system may include a mount that allows the retainer to rotate relative to the anchor pad.

  • SURGICAL FASTENER DEPLOYMENT SYSTEM
    Publication number: 20170119381
    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.

  • Stylets for use with apparatus for intravascular placement of a catheter
    Patent number: 9636031
    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 for temporary placement on the patient's chest, and an ultrasound probe. The tip location sensor senses a magnetic field of 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 in the integrated system to enable guidance of the catheter tip to a desired position with respect to a node of the patient's heart. Stylets and catheters including various multiple bipolar and monopolar electrode configurations are also disclosed.

  • Flexible stretch stent-graft
    Patent number: 9622850
    Abstract: A stent device (10) comprises a first graft member (20), a second graft member and a stent frame (12) defining a central axis. The frame has an abluminal surface engaged with the first graft member and a luminal surface engaged with the second graft member such that the first graft member and the second graft member encapsulates the stent frame along the length of the central axis. The stent frame includes a configuration where the stent frame is disposed on a curvature such that the abluminal surface has a radius of curvature of approximately 20 millimeters about a center of the curvature and the luminal surface defines a substantially constant effective cross-sectional area at any portion generally transverse to the central axis of the stent frame disposed about the curvature.
