<p>A stent delivery system with a stabilizing manipulator handle (20) is disclosed. The system has a self-expanding stent (14) in a contracted condition disposed on the distal end (11) of a delivery catheter (10) and a retractable sheath (16) covering the stent (14). The delivery catheter (10) is advanced through a guiding catheter (38) to a desired location within a patient's body lumen. The manipulator handle (20) at the proximal end (13) of the delivery catheter (10) is attached to the guiding catheter (38). The handle (20) has a slidable stem (30) connected to the sheath (16), and features a screw down spacer between the distal end of the handle and the proximal end (21) of the guiding catheter. The spacer (40) situates the position of the guiding catheter (38) relative to the delivery catheter (10) even during deployment of the stent (14). Once the stent (14) is at the targeted site, the sheath (16) is retracted by pulling back on the stem (30) to expose the self-expanding stent (14). A stop (18) on the interior of the delivery catheter (10) positioned proximal to the stent (14) further prevents the latter from moving out of position when the sheath (16) is retracted.</p> |
