DELIVERY SYSTEM CATHETER WITH ROTATING DISTAL END

摘要

A delivery catheter used for the delivery and deployment of self expanding stents. A distal end portion is made rotatable relative to a proximal end portion allowing unwinding of a self expanding stent around the longitudinal axis of the catheter. The rotation of the distal end portion allows for untwisting or partial untwisting of a self-expanding stent which has a torsional pre-load in a compressed state in the catheter.
