1. A stent delivery system, comprising:
- an inner member;
wherein a stent receiving region is defined along the inner member;
a deployment sheath slidably disposed along the inner member; and
a stent holding member pivotably coupled to the inner member at a position proximal of the stent receiving region, the stent holding member being designed to shift between a first configuration where a distal end of the stent holding member contacts the inner member and a second configuration where the distal end of the stent holding member is radially spaced from the inner member, and wherein the stent holding member is in the first configuration when the stent holding member is not covered by the deployment sheath and wherein the distal end of the stent holding member is closer to the inner member when in the first configuration than when in the second configuration.

9. A stent delivery system, comprising:
-
an inner member; wherein a stent receiving region is defined along the inner member; a deployment sheath slidably disposed along the inner member; a stent retainer pivotably disposed adjacent to the stent receiving region, the stent retainer having an outwardly extending region, an angled region, and a distal end designed to be positioned distally of a proximal end of a stent disposed along the stent receiving region; and wherein the stent retainer is designed to shift between a first configuration and a second configuration, wherein when the stent retainer is in the first configuration the angled region is disposed radially outward of an outer surface of the stent and where the distal end of the stent retainer contacts the inner member, wherein when the stent retainer is in second configuration the distal end of the stent retainer is radially spaced from the inner member, wherein the stent retainer is in the first configuration when the stent retainer is not covered by the deployment sheath, and wherein the distal end of the stent retainer is closer to the inner member when in the first configuration than when in the second configuration. - View Dependent Claims (10, 11, 12, 13)

14. A stent delivery system, comprising:
-
an inner member; wherein a stent receiving region is defined along the inner member; a self-expanding stent disposed along the stent receiving region; a deployment sheath slidably disposed along the inner member; a stent retainer pivotably disposed adjacent to the stent receiving region, the stent retainer having an outwardly extending region, an angled region, and a distal end designed to be positioned distally of a proximal end of the stent; wherein the stent retainer is designed to shift between a first configuration and a second configuration, wherein when the stent retainer is in the first configuration the angled region is disposed radially outward of an outer surface of the stent and where the distal end of the stent retainer contacts the inner member, wherein when the stent retainer is in second configuration the distal end of the stent retainer is radially spaced from the inner member, wherein the stent retainer is in the first configuration when the stent retainer is not covered by the deployment sheath, and wherein the distal end of the stent retainer is closer to the inner member when in the first configuration than when in the second configuration; and wherein the angled region has an angle that remains constant when the stent retainer shifts between the first configuration and the second configuration. - View Dependent Claims (15, 16, 17)
