Abstract
Official abstract text for this publication.
An apparatus for endosurgical use includes an instrument having an end effector and a staple cartridge insertable into the end effector. The staple cartridge includes staples, staple apertures, a resistive member, and a medical fluid. When coupled to a power source, the medical fluid is vaporized by the resistive member and expelled out the staple apertures onto the stapled tissue. The power source may be contained within the instrument. In one configuration, a resistive strip with strip contacts may electrically couple to a conductor in the end effector. The medical fluid may also be divided into a plurality of sealant pads corresponding to the staple apertures, and the medical fluid may be a depolymerizable cyanoacrylate, a sprayable thermoplastic urethane, or any vaporizable medicament or pharmaceutical. The staple drivers may include one or more apertures to permit the medical fluid to pass through or around the staple drivers.
