Rotating handle on introducer allowing retraction of stent trigger wire

摘要

A handle (80,82 fig 1) for an implant deployment device or introducer converts rotational movement into longitudinal movement in order to provide controlled release of one or more trigger wires. The handle also allows the trigger wire to be withdrawn into the device so that it does not need to be separately removed. A preferred handle includes a rotatable portion 120 and a slidable portion (122). Releasable locks (88, 188) ensure that the handle is used to carry out implant deployment steps in a specific order. The trigger wires are normally associated with stent implants.
