Access site management system for percutaneous vascular access

A dynamic vascular access and closure device for radial cinching comprising:

• a tensioning tube comprising a resilient member disposed within the tensioning tube;
• a plurality of sutures extending axially between a distal end of the tensioning tube and a proximal end of the tensioning tube, wherein a proximal end of each of the plurality of sutures is configured to directly couple with the resilient member such that movement of the plurality of sutures causes compression or extension of the resilient member within the tensioning tube, and
• a tension lock having a first position and a second position;
• wherein:
• in the first position, the tension lock is configured to hold the resilient member in a compressed state, causing slack in the sutures;
• and
• in the second position, the tension lock is configured to permit extensions of the resilient member, causing tension in the sutures;
• wherein the resilient member is configured to transition between:
• a first position to cause the plurality of sutures to cinch a vascular access site situated between distal ends of the plurality of sutures when the distal ends of the plurality of sutures are attached to a blood vessel;
• and
• a second position when the distal ends of the plurality of sutures are pulled apart to open the vascular access site, wherein a first length of the resilient member in the first position is greater than a second length of the resilient member in the second position.
