Vascular closure device with retraction assembly for repositioning a footplate

1 . A vascular closure device configured to seal a puncture in an artery or vein, the vascular closure device comprising:

a deployment assembly having a proximal end and a distal end opposite the proximal end;

a suture carried by the deployment assembly;

a footplate carried by the deployment assembly and coupled to the suture, wherein the footplate is configured to exit the distal end of the deployment assembly for deployment in the puncture;

a retraction assembly coupled to the footplate, the retraction assembly configured to, after deployment of the footplate, retract the footplate in a proximal direction and comprising:

a tether;

a guide member with a proximal end, a distal end, and a lumen that extends from the proximal end to the distal end, wherein the lumen is configured to receive a guidewire therethrough;

wherein

the footplate includes an aperture through which the distal end of the guide member extends,

the guide member includes a footplate engagement member extending outward from a body of the guide member and configured to abut the footplate, and

retraction of the tether and abutment of the footplate engagement member with a proximal surface of the footplate causes a trailing end of the footplate to pivot back toward the distal end of the deployment assembly.

2 . The vascular closure device of claim 1 , wherein the tether is coupled to the footplate.

3 . The vascular closure device of claim 2 , wherein the tether comprises a filament.

4 . The vascular closure device of claim 2 , wherein the tether comprises a wire.

5 . The vascular closure device of claim 2 , wherein the tether extends through the deployment assembly.

6 . The vascular closure device of claim 2 , wherein the tether extends alongside the deployment assembly.

7 . The vascular closure device of claim 2 , wherein the footplate includes an engagement feature that is coupled to a distal end of the tether.

8 . The vascular closure device of claim 1 , wherein the guide member is engaged with the footplate.

9 . The vascular closure device of claim 1 , wherein advancement of the guide member in a distal direction until the footplate engagement member abuts the proximal surface of the footplate causes the footplate to pivot for retraction toward the distal end of the deployment assembly in a distal direction.

10 . The vascular closure device of claim 9 , wherein the guide member includes an advancement engagement member extending outward from the body of the guide member and configured to advance the guide member in the proximal direction, when a force is applied to the advancement engagement member.

11 . The vascular closure device of claim 10 , further comprising an actuator configured to pull the tether in a proximal direction in order to retract at least the footplate in a proximal direction that is opposite a distal direction.

12 . The vascular closure device of claim 11 , wherein the actuator comprises a push-pull member, a rotatable knob, a rotatable lever, or a slide.

13 . The vascular closure device of claim 1 , further comprising a sealing unit that includes the footplate and a sealing plug coupled to the suture and positioned proximal to the footplate.

14 . The vascular closure device of claim 1 , further comprising a movable lock positioned along the suture, and a tamper slidable along the suture, the tamper configured to slide the movable lock into engagement with the sealing plug.

15 . The vascular closure device of claim 1 , wherein the deployment assembly includes a release member and a delivery member, and wherein either or both of the release member and delivery member are movable relative to the other to release the footplate from the deployment assembly.

16 . The vascular closure device of claim 15 , wherein during retraction, a proximal end of the footplate is aligned toward an axis of the deployment assembly.
