Abstract
An apparatus for treating uterine disorders by effecting necrosis of the uterine endometrium. The apparatus has a catheter with a bladder which can be inflated with a hot medium. To prevent early inflation of the bladder, the apparatus has an occlusion member arranged between a reservoir which contains the inflation medium and the bladder.
Claims13
An apparatus for treating uterine disorders by effecting necrosis of a uterine endometrium, the apparatus comprising:
- a catheter having a proximal end and a distal end;
- a bladder attached to the proximal end for insertion into uterus and being distendable upon introduction of an inflation medium;
- a reservoir containing the inflation medium;
- heating means configured to heat the inflation medium to a necrosis temperature;
- and
- inflation means being operative for moving the inflation medium between the storage means and the bladder;
- wherein the apparatus further comprises a removable occlusion member arranged between the reservoir and the bladder to prevent flow of the inflation medium from the reservoir to the bladder.

A method of sterilising an apparatus for treating uterine disorders by effecting necrosis of a uterine endometrium, the apparatus comprising:
- a catheter having a proximal end and a distal end;
- a bladder attached to the proximal end for insertion into uterus and being distendable upon introduction of an inflation medium;
- a reservoir containing the inflation medium;
- heating means configured to heat the inflation medium to a necrosis temperature;
- inflation means being operative for moving the inflation medium between the storage means and the bladder;
- and
- an occlusion member which melts at a melting temperature which is lower than the necrosis temperature and which is arranged between the reservoir and the bladder to prevent flow of the inflation medium from the reservoir to the bladder
- the method comprising the steps of sterilising the apparatus by use of a process causing the apparatus to reach a sterilisation temperature which is lower than the melting temperature.
