Abstract:
1. A method for treatment of a puncture in a vessel wall, a puncture tract extending through tissue to the puncture, the method comprising: puncturing the tissue, through which the puncture tract extends, to the puncture at a location spaced apart from the puncture tract and within the tissue by distally advancing a manifold, with a plurality of needles mounted thereto, within a housing and toward the puncture; and inducing localized swelling of the tissue surrounding the puncture tract to close the puncture and the puncture tract by delivering a closure agent to the plurality of needles directly from the manifold and into the tissue surrounding the puncture tract from within the tissue, the closure agent comprising a biodegradable substance or inflammatory substance that causes a localized inflammation response; wherein the delivery is done with an apparatus for sealing a puncture tract disposed within tissue, the apparatus comprising: a housing; and the plurality of needles coupled to the housing, the plurality of needles configured to penetrate tissue surrounding the puncture tract to deliver the closure agent into the tissue, thereby sealing the puncture tract; wherein the apparatus is further comprising a stop configured to limit translation of the plurality of needles into the tissue, and wherein the stop is disposed upon an axially translatable shaft supporting an expandable member configured to be disposed within the puncture tract to stabilize the tissue during insertion of the plurality of needles.
