Delivery system for deploying a self-expanding tube, and method of deploying a self-expanding tube

A delivery system for deploying a self-expanding tube into a blood vessel, comprising:

• a tubular member configured for insertion into the blood vessel;
• an elongate body extending within a lumen of the tubular member;
• a self-expanding tube positioned radially between the tubular member and the elongate body;
• and
• a retaining member configured to selectively apply a retaining force longitudinally to a proximal region of the self-expanding tube,
• wherein the delivery system is configured to operate in a retraction mode in which the application of the retaining force allows relative movement longitudinally between the elongate body and a portion of the self-expanding tube that remains in engagement with the elongate body during longitudinal movement of the self-expanding tube in a proximal direction relative to the elongate body.

A delivery system for deploying a self-expanding tube into a blood vessel, configured to operate in a deployment mode and comprising:

• a tubular member configured for insertion into the blood vessel;
• an elongate body extending within a lumen of the tubular member;
• and
• a self-expanding tube positioned radially between the tubular member and the elongate body, wherein:
• the self-expanding tube comprises an elongate frame reversibly switchable from a radially expanded and longitudinally contracted state to a radially contracted and longitudinally expanded state;
• and
• a distal region of the elongate body comprises two end markers.
