DEVICE FOR INSTILLATION OF A CHEMICAL AGENT INTO THE ENDOMETRIAL CAVITY FOR PURPOSE OF GLOBAL ENDOMETRIAL ABLATION

摘要

A device for chemical endometrial ablation comprising an outer tube, a moveable cervical collar surrounding a portion of the outer tube and located near the distal end of the outer tube, an inner tube movable in a distal-proximal direction within the lumen of the outer tube, a porous and/or sponge-like material on the distal end of the inner tube within the lumen of the distal end of the outer tube having a size, shape, and expandability so that when the distal end of the inner tube within the distal end of the outer tube is moved in a distal direction in relation to the outer tube, the porous and/or sponge-like material expands to the approximate size of a uterus so as to contact the endometrium, a source of cauterizing agent, and means to cause the cauterizing agent to flow through the lumen of the inner tube onto the porous and/or sponge-like material. In operation, the cervical collar can be moved or advanced along the outer tube to the cervix and secured tightly around the external portion in order to prevent chemical cauterizing agent from entering the vagina.

1. A device for chemical endometrial ablation comprising an outer tube having a lumen, a proximal end, a distal end, and an inner diameter, a cervical collar surrounding a portion of the outer tube on the outer tube and moveable in relation to the outer tube, an inner tube having an outer diameter less than the inner diameter of the outer tube, the inner tube movable in a distal-proximal direction within the lumen of the outer tube, the inner tube having a proximal end and a distal end, a porous and/or sponge-like material on the distal end of the inner tube within the lumen of the distal end of the outer tube, the porous and/or sponge-like material having a size, shape, and expandability so that when the distal end of the inner tube within the distal end of the outer tube is moved in a distal direction in relation to the outer tube, the porous and/or sponge-like material expands to the approximate size of a uterus having an endometrium so as to contact the endometrium of the uterus, a source of cauterizing agent at the proximal end of the inner tube, and means to cause the cauterizing agent to flow through the lumen of the inner tube onto the porous and/or sponge-like material.
