MEDICAL DEVICE DELIVERY SYSTEM

摘要

A medical device delivery system can be used to advance a medical device to a target area within a patient's vasculature. The system can comprise a catheter, a support sheath, and a core member coupled to a medical device. The core member can be used to longitudinally advanced or retracting medical device within a lumen of the support sheath. The support sheath can be advanced within the catheter until a distal end of the support sheath contacts or abuts a reduced diameter section of the catheter lumen. Thereafter, the core member can be advanced into the catheter lumen toward the target area.

1. A medical device delivery system, comprising:
a support catheter having proximal and distal sections and a lumen having an inner shoulder separating the proximal and distal sections, the catheter lumen having a larger diameter in the proximal section than in the distal section; and an introducer sheath having a distal section and a lumen extending therethrough, the sheath being advanceable within the catheter lumen of the catheter proximal section to contact a distal end portion of the sheath against the catheter inner shoulder to stabilize the sheath within the catheter.
