Abstract

The present invention is directed to an anchor that is configured to minimize or overcome lateral rotational moments that could potentially cause the anchor to laterally roll out of its intended position during use. The anchor is shaped to allow for a low profile longitudinal position and expanded transverse position. A device is used to initially insert the anchor in the low profile longitudinal position and then longitudinally rotate the anchor into the expanded transverse position when it is inserted through an incision or opening. The anchor is positioned at an internal portion of the incision or opening such that it seals an internal side of the incision. A sealing plug positioned at an external portion of the incision or opening. The sealing plug and anchor are cinched together with a suture to facilitate rapid healing of the incision or opening.

14. An arteriotomy sealing device according to claim 11, wherein at least one of the at least two suture passageways is beveled and the suture is lubricated.

15. An arteriotomy sealing device according to claim 12 wherein the anchor further comprises an anti-roll tab extending from a side thereof.

16. A tissue puncture closure device, comprising:

a suture;

a rotateable anchor shaped to advance in a low profile longitudinal configuration and to automatically rotate into an expanded transverse configuration upon insertion through the tissue puncture, wherein the rotateable anchor includes at least one anti-rolling tab positioned to prevent the rotateable anchor from rolling in a lateral manner;
