Embodiment Construction

[0025] The following illustrative embodiments are described with reference to the accompanying figures in the context of fibroid treatment, and in particular removal of pedunculated fibroids. However, the disclosed electrosurgical devices are not limited to use in the removal of pedunculated fibroids. The device is suitable for removal of various pedunculated tissue structures such as, for example, polyps located in, for example, the gastrointestinal tract. Thus, while the description below primarily focuses on the removal of pedunculated fibroids, other pedunculated tissue structures can be removed by the disclosed device.

[0026] figure 1 Different anatomical locations of uterine fibroids that potentially afflict patients are illustrated. Submucosal fibroids 40 are located on the inner wall of the uterus 10 . Subserosal fibroids 20 are located on the lateral wall of the uterus 10 . Intramural fibroids 50 are located in wall 14 of uterus 10 . A pedunculated fibroid 30 i...

Abstract

An electrosurgical system includes a grasper and a snare that each includes electrodes. The grasper includes a first electrode that is attachable to a first output of an energy supply. The snare includes a second electrode that is attachable to a second output of the energy supply. When the first and second electrodes are coupled to the energy supply, the grasper and snare operate as a bipolar electrosurgical system. By grasping the tissue with the jaws of the grasper, the current path between the electrode on the snare and the electrode on the grasper is relatively short, and thus the system operates like a bipolar electrosurgical system. Accordingly, the applied energy can be focused to a small area, minimizing damage to surrounding tissue. In addition, energy suitable for coagulating the cut portion of the stalk of the removed tissue can be readily applied with the bipolar electrosurgical system.

Description

Background technique [0001] The present disclosure relates to systems for removing tissue from a patient, and in particular for removing pedunculated tissue structures such as polyps and pedunculated fibroids. [0002] Uterine fibroids are the most common pelvic tumors in women, affecting approximately one in four women of reproductive age. Uterine fibroids are usually noncancerous but can cause infertility or cause adverse effects if they occur during pregnancy. Typical symptoms include abnormal bleeding, pressure, or pain. [0003] Uterine fibroids are classified based on the location of the uterus. Submucosal fibroids form on the inner wall of the uterus; subserosal fibroids form on the outer wall of the uterus; intramural fibroids form within the uterine wall; and pedunculated fibroids are linked to the inside or outside of the uterus by a stalk wall. [0004] Current treatment for uterine fibroids involves both drugs and surgical techniques. Medications often do not ...
