1. A system for treating a target site in a tubular organ, the system consisting essentially of:
- an elongate delivery guide member having a proximal end and a distal end, the delivery guide member configured to direct at least one implant having an exterior and interior surface to an anatomical treatment site by manipulation by a user, the at least one implant having a delivery diameter prior to release of the at least one implant and located proximally of the distal end of the delivery guide member prior to release, and at least one releasable joint configured to maintain at least a section of the at least one implant at the delivery diameter until release of the at least one releasable joint, and a balloon catheter, wherein the delivery guide member is adapted for receipt within a lumen of the balloon catheter.

5. An implant delivery system comprising:
-
an elongate delivery guide member having a proximal end and a distal end, the delivery guide member configured to direct at least one implant having an exterior and interior surface to an anatomical treatment site by manipulation of the delivery guide member by a user, the at least one implant having a delivery diameter prior to release of the at least one implant and located proximally of the distal end of the delivery guide member prior to release, and at least one releasable joint configured to maintain at least a section of the at least one implant at the delivery diameter until release of the at least one releasable joint, wherein the delivery guide member has a diameter distally and proximally of the at least one implant that is substantially equal to the at least one implant delivery diameter, whereby a substantially atraumatic implant delivery system is provided.

6. An implant delivery system comprising:
-
an elongate delivery guide member having a proximal end and a distal end, the delivery guide member configured to direct at least one implant having an exterior and interior surface to an anatomical treatment site by manipulation by a user, the at least one implant having a delivery diameter prior to release of the at least one implant and located proximally of the distal end of the delivery guide member prior to release, and a plurality of releasable joints, each joint configured to maintain a section of the at least one implant at the delivery diameter until release of the releasable joints, wherein the system is adapted for sequential release of the releasable joints. - View Dependent Claims (7)
