1. A system for closing an opening in a vessel wall, wherein a tissue tract provides access to the opening for performing medical procedures, the system comprising:
a housing with a shaft extending from the housing;
an actuation handle operatively coupled to the proximal housing and configured to deploy a foot disposed distal the housing;
a needle actuation handle operatively coupled to a first needle to and configured deploy the first needle to penetrate the vessel wall and cooperate with the foot;
a suture comprising a first fitting and a plurality of pre-tied anchors, spaced apart along a length of the suture and between the first end to the second end of the suture, the first fitting being configured to cooperate with the first needle, wherein, upon
proximal movement of the first needle cooperating with the first fitting and deployed in tissue, the suture is configured to pull opposing edges of the vessel wall together and pull opposing edges of the tissue together to engage the plurality of pre-tied anchors against a distal surface of the tissue within the tissue tract and against a proximal surface of the vessel wall on anterior and posterior sides of the opening with a plurality of the plurality of the pre-tied anchors being disposed within the tissue tract and extending proximally towards a proximal end of the tissue tract, and
the engagement of the plurality of pre-tied anchors with the tissue and the vessel wall prevent pulling of the second end of the suture through the vessel wall without tails of the suture being tied in a knot.
