REDUNDANT TISSUE CLOSURE METHODS AND APPARATUSES

摘要

A tissue closure device including a tissue eversion apparatus, and a first and a second, redundant closure element that are placed on the external surface of a tissue puncture wound to enhance the efficacy of closure. The first closure element and the second closure element are left resident on the external surface of or in proximity to the tissue puncture wound in order to provide redundancy of closure.

主权项

1. A method of closing an opening in a body lumen, comprising:
(a) deploying a tissue eversion apparatus into the opening in the body lumen; (b) everting edges of the opening with a plurality of elongate tissue engaging members to form an everted tissue region; (b) deploying a first closure element in a first configuration to the everted tissue region around the opening in the body lumen; (c) transitioning the first closure element to a second smaller configuration so as to close the opening in the body lumen; and (d) retracting the tissue eversion apparatus so as to release the everted edges.
