<p>Apparatus for facilitating deployment of a an implantable medical device includes a control member (20) having at least one tine member (35-37). A proximal region (35b-37b) of at least one of the tine members (35-37) is configured to engage an associated portion of a stent (60). In use, the control member (20) comprises a contracted delivery configuration in which the proximal region of the at least one of the tine member (35-37) is radially contracted, to radially constrain the associated portion of the stent (60). The control member (20) also comprises an expanded configuration in which the proximal region of the at least one of the tine member (35-37) expands radially outward relative to the central longitudinal axis to allow the stent to engage a body passage. The proximal region of the at least one tine member (35-37) is selectively movable an incremental amount between the contracted and expanded configurations, in radially inward and outward directions, to facilitate positioning of the stent (60) within the body passage.</p> |
