Abstract:
1. A method comprising: a. inserting an anchor across a vessel wall into a lumen defined by the vessel wall through a first arteriotomy that has a first angle with respect to the vessel wall; b. applying a force to the anchor to position an adjacent portion of the vessel wall in a desired configuration relative to the anchor; c. creating a tract between an exterior portion of a vessel wall and a lumen defined by the vessel wall with a device passing though a proximal extension of the anchor, while maintaining the vessel wall portion in the desired configuration with the anchor wherein a distal portion of the tract defines a second angle with respect to the vessel wall and wherein the first angle is larger than the second angle; and d. expanding the tract with a sheath so that a procedure may be performed therethrough, wherein the tract is defined between overlapping tissue portions of the vessel wall, and wherein after the procedure has been performed and the device and sheath have been withdrawn from the tract, blood pressure acting on the vessel causes the overlapping tissue portions to collapse and self-seal.
