Vascular closure devices and methods of use

A system for sealing a percutaneous puncture in a vessel wall, the system comprising:

• an anchor having:
• a first end, a second end, a length that extends from the first end to the second end, a lower surface, a wall engaging surface opposite the lower surface, a thickness that extends from the wall engaging surface to the lower surface, a first opening, and a second opening separate from the first opening, wherein the first and second opening extend from the wall engaging surface toward the lower surface, and the thickness is perpendicular to the length;
• a suture that extends through the first opening of the anchor;
• and
• an elongated tube having a proximal end, a distal end opposite the proximal end in a distal direction, and a tube lumen that extends from the distal end of the elongated tube toward the proximal end of the elongated tube, wherein the elongated tube extends through the second opening of the anchor along the thickness of the anchor so that the distal end of the elongated tube is spaced from the anchor in the distal direction.

A vascular closure system for sealing a puncture in a vessel wall, comprising:

• an anchor configured to seal the puncture in the vessel wall, the anchor having a lower surface and a wall engaging surface opposite the lower surface, a first opening and a second opening that extend from the wall engaging surface to the lower surface;
• a suture that extends at least through the first opening of the anchor;
• a tension cartridge coupled to the suture and configured to control application of tension to the suture;
• and
• an elongated tube having a proximal end, a distal end spaced from the proximal end of the elongated tube in a distal direction, and a guide lumen that extends from the distal end toward the proximal end, wherein the elongated tube extends through the tension cartridge and the second opening of the anchor such that the distal end of the elongated tube is spaced apart from the anchor in the distal direction, wherein the guide lumen is configured to receive a guidewire such that the anchor and the elongated tube are slidable along the guidewire.
