Sheath apparatus and methods for delivering a closure device
First Claim
1. An apparatus for delivering a closure element into an opening through tissue, comprising:
- an elongate member comprising proximal and distal ends defining a longitudinal axis therebetween, and an outer surface extending between the proximal and distal ends;
a carrier assembly slidable on the elongate member from the proximal end towards the distal end;
a closure element carried by the carrier assembly, the closure element being deployable from the carrier assembly; and
a skin overlying at least a portion of the outer surface of the elongate member and the carrier assembly, the skin being separable from the outer surface of the elongate member as the carrier assembly is advanced from the proximal end towards the distal end of the elongate member.

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.

21. An apparatus for delivering a closure device, comprising:
-
a sheath comprising a lumen extending between proximal and distal ends thereof;
a carrier assembly slidable along an outer surface of the sheath;
a closure element carried by the carrier assembly;
an actuator assembly comprising one or more actuator elements coupled to the carrier assembly for advancing the carrier assembly towards the distal end of the sheath; and
a skin overlying at least a portion of the outer surface between the carrier assembly and the distal end of the sheath, and at least partially overlying the carrier assembly, the skin being separable from the outer surface as the carrier assembly is advanced towards the distal end of the elongate member. - View Dependent Claims (22, 23, 24, 25, 26, 27, 28, 29, 30, 31)

32. A method for delivering a closure element to seal an opening through tissue, the closure element being carried by a carrier assembly slidable on an outer surface of an elongate member, the elongate member comprising a skin overlying at least a portion of the outer surface between the carrier assembly and a distal end of the elongate member and at least partially overlying the carrier assembly, the method comprising:
-
inserting the distal end of the elongate member into an opening through tissue;
advancing the carrier assembly towards the distal end of the elongate member, the carrier assembly causing the skin to separate from the outer surface of the elongate member as the carrier assembly is advanced towards the distal end; and
deploying the closure element from the carrier assembly within the opening. - View Dependent Claims (33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44)
