First Claim
Patent Images
1. An electrode assembly for a resectoscope, comprising:
- a cutting electrode with a loop distal tip;
a coagulation electrode with a loop distal tip in fixed physical relationship with the cutting electrode loop distal tip; and
a support frame connected to the cutting and coagulation electrodes and adapted to be coupled to an energy source to split and supply energy from the energy source to both the cutting and coagulation electrodes, wherein the coagulation electrode provides tissue coagulation simultaneously while the cutting electrode cuts tissue.

Abstract
An electrode assembly for a resectoscope includes, a cutting electrode with a loop distal tip and a coagulation electrode with a loop distal tip. A support frame connects the cutting and coagulation electrodes to an energy source which supplies energy from the energy source to the electrodes. The coagulation electrode provides tissue coagulation simultaneously while the cutting electrode cuts tissue. A resectoscope is disclosed which includes the electrode assembly. The resectoscope includes a sheath with a sheath lumen, a working element, and a visualization apparatus.
