Abstract
The disclosure provides a dynamic vascular access and closure device for radial cinching of an access site. The device includes a tensioning tube, a resilient member disposed within the tensioning tube, and a plurality of sutures extending axially between a distal end of the tensioning tube and a proximal end of the tensioning tube. A proximal end of each of the plurality of sutures can be configured to attach to the resilient member such that movement of that suture causes compression or extension of the resilient member within the tensioning tube to provide cinching to the sutures.
Claims20
A dynamic vascular access and closure device for radial cinching comprising:
- a tensioning tube comprising a resilient member disposed within the tensioning tube;
- and
- 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 attach to the resilient member such that movement of the plurality of sutures causes compression or extension of the resilient member within the tensioning tube.
A dynamic vascular access and closure device comprising:
- a plurality of sutures each having a proximal end and a distal end, each of the plurality of sutures having a suture stop at the corresponding proximal end;
- a tensioning tube assembly comprising:
- a body having distal end and a proximal end, and
- a spring;
- wherein each of the plurality of sutures extends axially through the body of the tensioning tube;
- and
- wherein tensioning of the plurality of sutures causes application of pressure to the spring, via the suture stops.
A dynamic vascular access and closure device for radial suture cinching comprising:
- a plurality of vascular anchors configured for attachment to a blood vessel;
- a plurality of sutures each having a proximal end and a distal end, wherein the proximal end of each suture has a suture stop and the distal end of each suture is connected to one of the plurality of vascular anchors;
- a tensioning tube having a distal end and a proximal end, the distal end of the tensioning tube having a smaller diameter than the proximal end of the tensioning tube;
- an inner biasing tube disposed at least partially inside the proximal end of the tensioning tube;
- a compression spring having a distal end and a proximal end, the spring being disposed inside the tensioning tube between the tensioning tube and the inner biasing tube, wherein the distal end of the compression spring contacts a shoulder of the tensioning tube and the proximal end of the compression spring contacts a distal end of the inner biasing tube;
- and
- a suture lock disposed between the distal end of the tensioning tube and the plurality of vascular anchors;
- wherein:
- the plurality sutures extend axially through the tensioning tube, the inner biasing tube, the compression spring, and the suture lock,
- a proximal end of the inner biasing tube contacts the suture stops of the plurality of sutures, and
- the inner biasing tube is configured to transfer spring force from the compression spring to the plurality of sutures to tension the plurality of sutures against the plurality of anchors to cause opening or closing of a vascular access site located between the plurality of anchors when deployed on a blood vessel.
