Abstract
Embodiments of the present invention are directed to devices for allowing a user to deploy a stent in an anatomical lumen of a patient. For example, one embodiment is directed to a device including a longitudinally extending inner tubular member and a longitudinally extending outer tubular member that are longitudinally and axially displaceable relative to one another. The outer tubular member includes at least one longitudinally extending channel formed between the exterior and interior diameter of the outer tubular member. In addition, the device includes a handle configured to displace the outer tubular member and inner tubular member relative to each other in response to user intervention and a stop configured to coaxially engage the handle to form a safety mechanism. Displaceability of the outer tubular member and inner tubular member relative to each other is limited by the safety mechanism to a predetermined threshold.
