Sheath apparatus and methods for delivering a closure device
First Claim
1. An apparatus for delivering a closure clip into an opening through tissue, comprising:
- an elongate member comprising a lumen extending from a proximal end to a distal end, a hub being disposed at the proximal end;
an obturator slidably advanceable through the lumen, the obturator comprising an expandable distal end; and
a handle assembly that selectively connects to the hub of the elongate member, the handle assembly selectively advancing a closure clip from a position that is closer to the hub than to the distal end of the elongate member to engage with the tissue surrounding the opening to close the opening.

Abstract
An apparatus for delivering a clip includes an introducer sheath including an outer surface extending between its proximal and distal ends. A clip is carried on the outer surface, e.g., on a carrier assembly that is slidable along the outer surface from the proximal end towards the distal end. A skin overlies the outer surface of the sheath and the carrier assembly that is separable from the outer surface as the carrier assembly is advanced from the proximal end towards the distal end of the sheath. During use, the distal end of the sheath is inserted into an opening through tissue, e.g., into a puncture communicating with a blood vessel. The carrier assembly is advanced towards the distal end of the sheath, causing the skin to separate from the outer surface of the elongate member, and the clip is deployed from the carrier to seal the opening.

8. An apparatus for delivering a closure clip into an opening through tissue, comprising:
-
an elongate member comprising a lumen extending from a proximal end to a distal end, a hub being disposed at the proximal end, the lumen being configured to receive a guidewire; a handle assembly separate from the elongate member and selectively mounted to the hub of the elongate member when the elongate member is placed in vivo, the handle assembly and the elongate member being movable together following mounting together, the handle assembly comprises a control shaft, the handle assembly selectively deploying a closure clip to engage with the tissue surrounding the opening to close the opening, and an expandable member slidably advanceable through the lumen, the expandable member comprising a selectively expandable and collapsible distal end and being configured to present tissue towards the closure clip. - View Dependent Claims (9, 10, 11, 12, 13)

14. An apparatus for delivering a closure clip into an opening through tissue, comprising:
-
an elongate member comprising a lumen extending from a proximal end to a distal end, a hub being disposed at the proximal end, the lumen being configured to receive a guidewire and the hub comprising a bleed back indicator side port; a handle assembly that lockingly mounts to the hub of the elongate member so that the elongate member and a portion of the handle assembly are movable together, the handle assembly selectively deploying a closure clip, from a position that is closer to the hub than to the distal end of the elongate member, to contact the tissue surrounding the opening to close the opening; and an obturator slidably advanceable through the lumen. - View Dependent Claims (15, 16, 17, 18, 19, 20)
