Abstract:
An endoprosthesis delivery catheter system, comprising:a shaft assembly extending between a proximal end portion and a distal end portion, the distal end portion being capable of carrying an endoprosthesis to a placement site;a ring component;a tubular element having a first end, in end to end facing relationship with the ring component while carried on the distal end of the shaft, and a second end remote from the first end, anda tubular casing being in tension around the circumference of the shaft to enhance its frictional contact with the shaft and extending along the shaft over a radially outer surface of the tubular element, and along the shaft radially inside the ring component, enabling the tubular element to resist unwanted axial sliding movement of the ring component on the shaft.
