Abstract
A device for sterilizing females by occluding the uterotubal junction. The device includes a catheter with a releasable heat generating plug which is used to thermally damage the uterotubal junction and cause it to constrict around the plug, after which the plug is released from the catheter and left in place in the uterotubal junction.
Claims2
A method of sterilizing a female, said method comprising the steps of:
- (a) providing an elongated instrument assembly having a distal end portion;
- (b) inserting the distal end portion of the instrument assembly into the patient's uterotubal junction;
- (c) operating the instrument assembly to deliver radio frequency energy from the instrument to the uterotubal junction, causing the tissue of the uterotubal junction to collapse on the distal end portion;
- (d) detaching the distal portion of the instrument from the remainder of the instrument;
- (e) removing the remaining portion of the instrument from the patient.
2 more elements
A method of sterilizing a female, said method comprising:
- providing a catheter having a plug releasably mounted on the distal end of the catheter;
- and providing an energy source operably connected to the plug and capable of heating the plug;
- inserting the catheter into the uterus of the female, and inserting the plug into a uterotubal junction of the female;
- operating the energy source to heat the plug, thereby causing the tissue of the uterotubal junction to collapse upon the plug;
- releasing the plug from the distal end of the catheter.
