Problems solved by technology

This technique neither manages the thickness variation of the endometrial tissue at the isthmus of the fallopian tube nor the tight tolerances required for the depth of disruption within the fallopian tube

Embodiment Construction

[0029] The present invention describes a method and system for occluding a female fallopian tube, which provides a minimally invasive alternative to female sterilization. Referring to FIG. 1A , there is shown a schematic diagram of a uterus 3 comprising a uterine cavity 5 surrounded by uterine tissue (ie, endometrial tissue 7a and uterine muscular tissue 7b ). The fallopian tube 11 connects with the uterine cavity 5 at the isthmus 9 of the fallopian tube. Occlusion of the isthmus 9 prevents sperm from entering the fallopian tube 11 and from fertilizing an egg, thus rendering the female sterile.

[0030] Referring to FIG. 1B , an RF (radio frequency) applicator head 2 may be introduced into the uterine cavity through the cervix and positioned at the isthmus 9 of the fallopian tubes. RF energy is sent through the RF applicator head 2 to ablate uterine tissue 7a, 7b and tissue within the isthmus 9, as shown in area 11 in FIG. 1C. Following tissue destruction at the isthmus 9, t...

Abstract

A medical device and procedure is described for occluding a fallopian tube. A tubal occlusion device is inserted into a uterine cavity. The device includes an RF applicator head including an electrode carrier with one or more bipolar electrodes thereon. During insertion, the RF applicator head can be in a closed position. The RF applicator head is positioned at a tubal ostium of a fallopian tube, such that a distal tip of the RF applicator head advances into the tubal ostium. The RF applicator head is deployed into an open position such that the RF applicator head approximates the shape of the uterine cavity in a region of the tubal ostium. Current is passed through the one or more bipolar electrodes to the tubal ostium to destroy tissue to a known depth, which precipitates a healing response in surrounding tissue that over time scars and occludes the fallopian tube.

Description

technical field [0001] The present invention relates to a medical device and surgical procedure. Background technique [0002] Female sterilization usually involves blocking the fallopian tubes to prevent sperm from getting into an egg in a woman's fallopian tubes. One traditional surgical procedure for female sterilization is laparoscopic tubal occlusion. During this procedure, an incision is made in the abdominal wall to provide access to the fallopian tubes. With the aid of a laparoscope, the fallopian tubes are occluded surgically, for example with bipolar or monopolar coagulation. Laparoscopic tubal occlusion is invasive, requiring multiple incisions, and access to the patient's abdomen with several instruments and gaseous dilation media. Thermal and mechanical damage to surrounding tissues and organs has been reported. [0003] A minimally invasive transcervical approach for female sterilization has recently been used. One such procedure involves the placement of ...
