Abstract

Apparatus is provided for sealing a vascular puncture by causing a reduction in the circumference of the puncture tract through delivery of a closure agent into tissue surrounding the puncture tract. A resultant inflammatory response and volumetric increase cause the tissue to swell into the puncture tract, thereby sealing it.
