摘要：
The present invention, in an exemplary embodiment, provides a stent deployment apparatus comprising safety and stent placement and deployment features. An exemplary stent deployment apparatus includes a longitudinally extending outer tubular member and a safety mechanism coupled thereto, wherein the safety mechanism includes a diverted channel. The apparatus also includes a longitudinally extending inner tubular member being longitudinally and axially displaceable relative to the outer tubular member, wherein the inner tubular member further comprises at least one detent along the longitudinal expanse thereof for operative interaction with the diverted channel. The extent of displaceability of the outer tubular member and inner tubular member relative to the other is limited to a predetermined threshold corresponding to engagement of the detent with the diverted channel absent intervention by the user of the device such that the degree of stent deployment is limited absent the user intervention.
