Abstract
The present invention, in an exemplary embodiment, provides a stent deployment apparatus comprising excellent safety and stent placement and deployment features. An exemplary stent deployment apparatus in accordance with the present invention can facilitate the precise delivery of stents in a safe and repeatable fashion. In particular, a preferred deployment apparatus allows the physician to concentrate on correct placement without having to estimate extent of deployment by providing a physical safety mechanism that limits deployment to the critical deployment point. Moreover, to exceed this threshold, an audible and/or tactile indicator informs the physician that she can no longer retract the stent beyond this point. The stent deployment apparatus guidewire may also be extended rather than retracting the outer catheter to deliver the stent. Moreover, the distal tip is designed to comfortably guide the deployment apparatus through a diseased or occluded lumen so that the stent can be delivered in the most beneficial location. Additionally, the distal tip facilitates the removal of the deployment apparatus even if a defective stent is only partially radially expanded. In alternative…
