Electrosurgical device having a dielectric seal

Abstract

A method of manufacturing a seal in an electrosurgical device includes placing components of the electrosurgical device within an elongated housing section, the housing section including an actuator opening, introducing the housing section within a mold filled with a liquid thermoplastic elastomer and allowing the elastomer to flow within the housing, forming an elastomeric inwardly-extending lip portion circumferentially surrounding an opening at a distal end of the electrosurgical device for introducing an electrode therein, and allowing the molded elastomer to cure and become integral with the housing to seal the components within the molded elastomer contained within the housing section. The method may also include the step of forming an elastomeric actuator seal around the actuator opening.
