  • Vascular access to closure sheath and methods
    Patent number: 9282994
    Abstract: An insertion sheath and related methods include a tube member and a shape memory feature. The tube member defines an insertion lumen. The shape memory feature is positioned at a distal end portion of the tube member. The shape memory feature provides a monofold shape in the tube member when in a first state, and a radially expanded shape in the tube member in a second state upon application of an expansion force. The shape memory feature returns the monofold shape after removal of the expansion force. The insertion sheath may function as an access to closure sheath that is suitable for use as a procedural insertion sheath when treating the patient and a closure insertion sheath when sealing closed the vascular puncture.
