ABSTRACT:
A tubal sterilization device having sesquipolar electrodes includes a hollow catheter defining an interior passageway, the catheter including a first end for insertion transcervically into a patient, and a second end opposite the first end for grasping and manipulation by a physician. The device further includes an electrode tip situated at the first end of the catheter. The electrode tip includes a first portion having a first electrode, the first portion being preferably formed generally conically in shape so that it may be snugly fit into the tubal osteum of the fallopian tube. The electrode tip further includes a second portion having a second electrode which is a coil formed from a wire which is helically wrapped about an insulating spacer or support. The second portion of the electrode tip with the second electrode may be retracted within a bore formed axially within the first portion of the electrode tip and may selectively extended therefrom for placement within the intramural segment of the fallopian tube. A slider linkage within the hollow catheter moves the second portion and second electrode between its retracted position and extended position. Bipolar RF (radio frequency) energy is provided to the first and second electrodes to cause the selective heating of tissue within the intramural segment of the fallopian tube.
