Intraluminal stent assembly and method of deploying the same
First Claim
1. An intraluminal stent assembly comprising:
- a catheter including at least one lumen formed therein;
at least one inflatable member disposed on the catheter and in communication with the lumen, the inflatable member comprising at least one distal projection;
a self-expanding stent expandable from a compressed configuration to an expanded configuration, the stent disposed on the inflatable member in the compressed configuration;
a sheath slidably positioned over the stent wherein the stent expands to the expanded configuration upon retraction of the sheath;
wherein the inflatable member is inflated with a fluid flowing through the lumen;
wherein the distal projection retains the stent on the inflatable member while the stent is being deployed.

Abstract
Intraluminal stent assemblies and methods of deploying the same. The assemblies include a catheter including at least one lumen formed therein. At least one inflatable member is disposed on the catheter and in communication with the lumen. The inflatable member includes at least one distal projection and/or at least one retention material. A stent is expandable from a compressed configuration to an expanded configuration. The stent is disposed on the inflatable member in the compressed configuration. A sheath is slidably positioned over the stent wherein the stent expands to the expanded configuration upon retraction of the sheath. The inflatable member is inflated with a fluid flowing through the lumen. The at least one distal projection and/or at least one retention material retain the stent in position on the inflatable member while the stent is being deployed.

6. A method of deploying an intraluminal stent, the method comprising:
-
providing a self-expanding stent mounted on at least one inflatable member of an inflation catheter, the inflatable member comprising at least one distal projection;
positioning a sheath over the mounted stent;
positioning the mounted stent at a treatment site within a body lumen;
inflating the inflatable member;
retracting the sheath;
self-expanding the mounted stent;
retaining the stent during its expansion with the distal projection;
deflating the inflatable member; and
removing the inflation catheter from the body lumen whereby the expanded stent remains deployed at the treatment site in the body lumen. - View Dependent Claims (7, 8, 9, 10)
