Title: Electroresectroscope and method of laparoscopic tubal sterilization

Abstract: An elongate stylet slidably disposed within a thermoelectric insulative sheath has a forward-projecting surgically incisive tip for entry of the sheath into the peritoneal cavity. After the stylet is withdrawn, an elongate shaft having hook-shaped electrical resistance element extending forwardly therefrom is slidably inserted through the sheath and the resistance element engaged with a Fallopian tube. Subsequently, the sheath is moved forwardly to encase the resistance element in the doubled section of Fallopian tube engaged therewith. An electrical energy impulse from a controlled source thereof energizes the resistance element for concurrent electroresection and electrocoagulation of the Fallopian tube in an environment shielded from adjacent organs.
