Abstract
A delivery system, including an inner member, an outer tube surrounding the inner member and movable axially relative to the inner member, wherein a space is defined between an outer surface of the inner member and an inner surface of the outer tube, an expandable element disposed in the space at a distal portion of the system, and a patch disposed in the space at the distal portion of the system, wherein the patch is radially outward of the expandable element.
Claims20
A delivery system, comprising:
- an inner member;
- an outer tube surrounding the inner member and movable axially relative to the inner member, wherein a space is defined between an outer surface of the inner member and an inner surface of the outer tube;
- an expandable element disposed in the space at a distal portion of the system;
- and
- a patch disposed in the space at the distal portion of the system, wherein the patch is radially outward of the expandable element.

A delivery system, comprising:
- an inner member;
- an outer tube surrounding the inner member and movable axially relative to the inner member, wherein an annular space is defined between an outer surface of the inner member and an inner surface of the outer tube;
- a self-expanding stent disposed in the annular space at a distal portion of the system;
- a patch disposed in the annular space at the distal portion of the system, wherein the patch is radially outward of the stent;
- and
- a fluid lumen having an opening at a proximal end of the system and in fluid communication with the space;
- wherein the patch includes an adhesive on a radially outer surface of the patch and a non-adhesive on a radially inner surface of the patch in contact with the stent;
- wherein the length of the patch is less than the length of the stent;
- wherein a proximal most end of the stent is proximal to a proximal most end of the patch;
- wherein a gap is formed between two free ends of the patch, wherein the gap extends along the length of the patch;
- and
- wherein moving the outer tube proximally relative to the inner member exposes an entirety of the patch and at least a portion of the stent, so that the portion of the stent expands and applies a radial force to the patch.

A method of delivering a patch to a target tissue site, the method comprising:
- positioning a delivery system adjacent to the target tissue site, wherein the delivery system includes an outer tube surrounding an inner member, wherein a space is defined between an outer surface of the inner member and an inner surface of the outer tube, a stent is disposed in the space at a distal portion of the system, a patch is disposed in the space at the distal portion of the system, and the patch is radially outward of the stent;
- moving the outer tube proximally relative to the inner member exposing the patch and at least a portion of the stent, wherein the portion of the stent applies a radial force to the patch to apply the patch to the target tissue site;
- moving the outer tube distally relative to the inner member to retrieve the portion of the stent into the space;
- and
- withdrawing the delivery system from the target tissue site and leaving the patch adhered to the target tissue site.
