STENT DEPLOYMENT SYSTEM WITH REINFORCED INNER MEMBER

摘要

A stent deployment system with a reinforced inner member is disclosed. The system has a self-expanding stent in a contracted condition disposed on the distal end of a delivery catheter and a retractable sheath covering the stent. The delivery catheter is advanced through a guide catheter to a desired location within a patient's body lumen. Once the stent is at the target site, the sheath is retracted by pulling back on the stem to expose the self-expanding stent. The reinforced inner member provides longitudinal compression resitance for the delivery catheter, while allowing for flexibility for navigation through a tortuous vasculature.
