Linear Staplers Having Resorbable Microneedles Containing Active Agents

摘要

The present invention is directed to linear surgical staplers for joining tissue layers comprising a disposable cartridge installed in a first jaw connected to an opposing second jaw, said cartridge containing a plurality of deployable staples in arrays separated by a tissue resection slot and a plurality of resorbable medicant-releasing microneedles, said microneedles comprising elongated rods having a sharp tissue-penetrating distal end and a proximal end; said microneedles are releasably disposed on or within a tissue-facing surface of the cartridge, wherein the proximal end of the microneedles is supported on the cartridge. The present invention is also directed to methods of use of such stapler assembly devices.
