Abstract: An end effector assembly for use with an electrosurgical instrument is provided. The electrosurgical instrument includes a handle having a shaft that extends therefrom, an end effector disposed at a distal end of the shaft, at least one electrode operably coupled to the end effector and adapted to couple to a source of electrosurgical energy, a chromium nitride coating covering at least a portion of the electrode, and a hexamethyldisiloxane plasma coating covering at least a portion of the chromium nitride coating.

Abstract: A method for coupling a body conduit to tissue is provided. The method includes engaging an implant about an outer surface of a catheter. The implant receives a bioactive agent having tissue growth properties. The method involves inserting the catheter through the body conduit and into a tissue opening across a resected area, positioning the implant in the resected area, inflating a balloon to anchor the catheter within the tissue opening such that the implant bridges the body conduit and the tissue opening across the resected area, and maintaining the catheter and the implant in vivo to enable the bioactive agent to secure the implant in the resected area to permanently bridge the body conduit and the tissue opening.

Abstract: An electrosurgical suction coagulator includes a housing having proximal and distal ends and an elongated tube-like shaft extending longitudinally from the distal end of the housing. The elongated tube-like shaft includes a tube-like dielectric sheath, a tube-like conductor, and an external insulator. The tube-like conductor is disposed coaxially through the tube-like dielectric sheath. The distal end of the tube-like conductor protrudes at least partially from the distal end of the tube-like dielectric sheath. The external insulator is disposed coaxially around the tube-like dielectric sheath. The external insulator extends from about the proximal end of the dielectric sheath to about the distal end of the dielectric sheath.
