Apparatus and methods for delivering a closure device
First Claim
1. A method of closing an opening in tissue, comprising:
- disposing a sheath through a tissue path and into the opening;
coupling an actuator member to a proximal end of the sheath, the actuator member including a plurality of tubular members, wherein a clip including a plurality of distally oriented tissue penetrating tines is slidably disposed adjacent a distal end of one of the tubular members;
distally advancing an obturator assembly beyond a distal end of the clip;
deploying the obturator assembly to cause at least one expandable element to expand and distend at an angle from the sheath; and
delivering the clip to close the opening.

Abstract
An apparatus for delivering a clip to close an opening through tissue includes a sheath and a carrier assembly including a clip therein that is slidable on the sheath. An actuator assembly is connectable to the sheath, and telescoping actuator members extend from the handle that are connectable to the carrier assembly for advancing the carrier assembly along the sheath. An obturator on the actuator assembly includes splines that may be deployed beyond a distal end of the sheath, and expanded to a transverse expanded configuration for positioning the sheath before deploying the clip. The actuator members include cooperating detents that selectively release the actuator members as the carrier assembly reaches predetermined positions along the sheath for deploying the clip from the carrier assembly, and that collapse the splines to allow removal of the apparatus after deploying the clip.

10. A method of closing an opening in a vessel with a clip, comprising:
-
inserting a sheath into a vessel; performing a medical procedure; coupling an actuator member to a proximal end of the sheath, the actuator member including a plurality of tubular members, wherein a clip including a plurality of distally oriented tissue penetrating tines is slidably disposed adjacent a distal end of one of the tubular members; distally advancing an obturator assembly beyond a distal end of the clip; and after distally advancing the obturator assembly beyond the distal end of the clip, delivering the clip to close the opening, the delivering including driving at least one of the tissue penetrating tines into or through a portion of the vessel to be closed. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18)

19. A method of closing an opening in tissue, comprising:
-
inserting a sheath into a vessel; performing a medical procedure; coupling an actuator member to a proximal end of the sheath, the actuator member including a plurality of tubular members, wherein a clip including a plurality of distally oriented tissue penetrating tines is slidably disposed adjacent a distal end of one of the tubular members; distally advancing an obturator assembly beyond a distal end of the clip; deploying the obturator assembly to cause at least one expandable element to distend at an angle relative to an axis of the sheath to locate the clip relative to the tissue; and after distally advancing the obturator assembly beyond the distal end of the clip and after deploying the obturator assembly to cause at least one expandable element to distend at the angle relative to the axis of the sheath to locate the clip relative to the tissue, delivering the clip to close the opening, the delivering including sliding the clip distally so as to drive at least one of the tissue penetrating tines into or through the tissue adjacent to the opening. - View Dependent Claims (20)
