Patent ID: 7637934

Claim:
A device for allowing a user to deploy a stent in an anatomical lumen of a patient, the device comprising: a longitudinally extending inner tubular member having distal and proximal ends, the inner tubular member defines a lumen longitudinally extending substantially the distance from the distal end to the proximal end of the inner tubular member and forming a longitudinal expanse there between, the longitudinal expanse forming an aperture there through, and the inner tubular member having a tip coupled with the distal end; a longitudinally extending outer tubular member having an exterior and interior diameter, the outer tubular member being longitudinally and axially displaceable relative to the inner tubular member and including at least one longitudinally extending channel formed between the exterior and interior diameter of the outer tubular member; a handle configured to displace the outer tubular member and inner tubular member relative to each other in response to user intervention, the handle coupled with the outer tubular member, the handle having first and second ends and the second end including a cavity defined therein; a stop disposed substantially about a circumference of the inner tubular member and configured to coaxially engage the cavity within the handle to form a safety mechanism; whereby displaceability of the outer tubular member and inner tubular member relative to each other is limited by the safety mechanism to a predetermined threshold absent intervention by the user of the device such that the outer tubular member is configured to partially surround the stent at the predetermined threshold and the stent is not fully deployed when the stop is engaged with the cavity.
