  • Apparatus and methods for delivering a closure device
    Publication number: 20020026208
    Abstract: An apparatus for delivering a closure element into a puncture communicating with a blood vessel includes an introducer sheath, and a locator member disposed within the sheath, the locator member having a distal portion extending distally beyond the distal end of the sheath. A plurality of splines are provided on the distal portion of the locator member, the splines being selectively expandable between an axial collapsed configuration and a transverse expanded configuration. An actuator is coupled to the locator member for controllably expanding the splines. A housing is slidably disposed on the sheath for deploying a closure element, such as a vascular clip. The locator actuator may automatically collapse the splines upon advancement of the housing.

  • Vascular sheath with puncture site closure apparatus and methods of use
    Publication number: 20010007077
    Abstract: Apparatus and methods are provided for use in sealing a vascular puncture site. The invention comprises an introducer sheath with an integrated closure component. The closure component includes an advanceable resilient spring clip with an expanded delivery configuration in which opposing sides do not contact one another, and an unstressed deployed configuration, in which opposing sides close towards one another. The clip is advanced along the sheath until it pierces opposing sides of a vessel wall at a puncture site. The sheath then is withdrawn, thereby causing the clip to resiliently return to its unstressed deployed configuration and draw opposing sides of the puncture together to seal the wound.
