Abstract
An intrauterine ablation device having a catheter, a handle, and a distensible bladder. The catheter contains a joint such that the catheter may be articulated to facilitate access into the uterus.
Claims4
A uterine balloon treatment apparatus, comprising:
- a catheter having a longitudinal internal passage, a distal end and a proximal end, said catheter being flexible;
- a slidable collar mounted on said catheter such that when the collar is bent, the catheter is angulated;
- an inflatable balloon mounted to the distal end of the catheter, said inflatable balloon having an interior, wherein the interior of the inflatable balloon is in fluid communication with the internal passage of the catheter, and a proximal end with a proximal opening and a distal end;
- a handle having a hollow, longitudinal passage mounted to the proximal end of the catheter such that the interior passage of the handle is in fluid communication with the interior passage of the catheter;
- a connector mounted to the handle for connecting the passage of the catheter to a source of liquid;
- a heating element mounted in the internal passage of the catheter such that when said heating element is connected to a source of electrical power it generates heat;
- and,
- an electrical conductor mounted in the apparatus for providing electrical power to the heating element.

A method of ablating endometrial tissue form the interior of a uterus comprising the steps of:
- A. providing a uterine ablation apparatus comprising:
- a catheter having a longitudinal internal passage, a distal end and a proximal end, said catheter being flexible;
- a slidable collar mounted on said catheter such that when the collar is bent, the catheter is angulated;
- an inflatable balloon mounted to the distal end of the catheter, said inflatable balloon having an interior, wherein the interior of the inflatable balloon is in fluid communication with the internal passage of the catheter, and a proximal end with a proximal opening and a distal end;
- a handle having a hollow, longitudinal passage mounted to the proximal end of the catheter such that the interior passage of the handle is in fluid communication with the interior passage of the catheter;
- a connector mounted to the handle for connecting the passage of the catheter to a source of liquid;
- a heating element mounted in the internal passage of the catheter such that when said heating element is connected to a source of electrical power it generates heat;
- and,
- an electrical conductor mounted in the apparatus for providing electrical power to the heating element;
- B. inserting the balloon and distal end of the catheter into a uterus having an endometrial layer;
- and,
- C. heating the endometrial layer to a sufficient temperature for a sufficient length of time to effectively ablate the layer.
