Vascular sheath with puncture site closure apparatus and methods of use
First Claim
1. Apparatus for sealing a puncture in a vessel wall comprising:
- an introducer sheath having proximal and distal regions and an exterior surface;
a housing coaxially and slidably disposed on the exterior surface of the introducer sheath, the housing including a portion defining a chamber;
a clip resiliently expandable from an unstressed, deployed configuration wherein opposing sides of the clip are directed inwards towards one another, and an expanded, delivery configuration, in which the clip is slidably accepted within the chamber; and
an actuator for deploying the clip from the chamber into engagement with the vessel wall to close the puncture.

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 The sheath then is withdrawn, thereby causing the clip to resiliently return to its unstressed deployed configuration and draw opposing sides of the puncture together to seal the wound.

13. A method of sealing a puncture in a vessel wall, the method comprising:
-
providing apparatus comprising an introducer sheath having proximal and distal regions and a lumen extending therebetween, a housing slidably and coaxially disposed on the proximal region of the introducer sheath, a resilient clip disposed within the housing in an expanded delivery configuration, and a clip actuator;
inserting the distal region of the introducer sheath through a patient'"'"'s skin into a vessel via the puncture;
performing an interventional or diagnostic procedure by advancing a device through the lumen of the introducer sheath;
upon completion of the procedure, coupling the clip actuator to the housing;
advancing the clip and housing through the skin with the clip actuator until the clip pierces the vessel wall on opposing sides of the puncture; and
withdrawing the introducer sheath, housing, and clip actuator from the puncture so that the clip returns to an unstressed deployed configuration and seals the puncture. - View Dependent Claims (14, 15, 16, 17)

18. Apparatus for sealing a vascular puncture comprising:
-
an introducer sheath having proximal and distal regions, a lumen extending therebetween, and an exterior surface;
an expander having an exterior surface, the expander slidably and coaxially disposed on the exterior surface of the introducer sheath;
a housing coaxially disposed on and cammingly engaged with the expander, the housing including a portion defining a chamber;
a resilient clip having an unstressed, deployed configuration, in which the clip closes the puncture, and an expanded, delivery configuration, in which the clip slidably passes over the exterior surface of the expander; and
an actuator operably coupled to the housing for deploying the clip from the chamber. - View Dependent Claims (19, 20, 21, 22, 23, 24)
