Apparatus and methods are provided to concentrate energy delivery in non-superficial target tissue within a trigone region of a human bladder wall to modulate bladder function.

A system for accessing a patient's uterine cavity and detecting perforations in the uterus includes an elongated probe having a flow channel extending to a terminal outlet in a distal region of the probe. A fluid source is coupled to the flow channel, and a seal on the probe is positionable in an endocervical canal. The probe may be trans-cervical inserted into the uterine cavity, and a fluid may be introduced through the channel to flow outwardly from the terminal outlet into the uterine cavity. A parameter of said fluid flow is monitored to detect a perforation in the uterus.

A treatment tool includes: an insertion portion including a plurality of holes; a shaft that is arranged in the insertion portion; a plurality of needles that are connected to the shaft, each needle being configured to move between a first position and a second position; a plurality of first insulating materials, each insulating material being configured to cover the needle; and an energy supplier configured to supply electric power to the plurality of needles. The hole is configured to regulate a protruding direction of the needle to a direction intersecting with the longitudinal direction of the insertion portion. When an area that is positioned outside the insertion portion out of a whole area of the needle at the first position is sectioned into two areas that are a first area and a second area, the first insulating material is configured to cover the second area.

Surgical handheld devices are used in electrosurgical procedures in urology. For this use, a radiofrequency electric current is applied to an electrode. It is necessary to avoid the electrode coming into electrical contact with the handheld device. Known insulation inserts for electrical insulation can be connected to the handheld device only with difficulty. Moreover, the connection is very unreliable. A surgical handheld device, and an insulation insert which can be connected to a shaft of the handheld device in a safe and easily releasable manner. The insulation insert is of a tubular configuration and is releasably coupled with a proximal end region to a distal end of a tubular shaft of the handheld device. The proximal end region of the insulation insert has at least two resilient fasteners, which each have a latch element pointing into an interior of the insulation insert.

An electrosurgical probe with internal cooling for use in systems and methods for lesioning in bone and other tissue is disclosed. The probe includes a distal electrical insulator, a proximal electrical insulator, a distal electrical conductor defining a distal electrode with a closed distal end and a proximal electrical conductor defining a proximal electrode, the distal electrode longitudinally spaced apart and electrically isolated from the proximal electrode by the distal electrical insulator. The distal electrode has a closed proximal end formed by a distal face of the distal electrical insulator to thereby define a closed distal inner lumen for circulating the cooling fluid. The proximal electrode has a closed distal end formed by a proximal face of the distal electrical insulator and a closed proximal end formed by a distal face of the proximal electrical insulator to thereby define a closed proximal inner lumen for circulating the cooling fluid.

The tissue cutting device comprises an elongated assembly including both an outer sleeve and an inner sleeve. The outer sleeve has a tissue-receiving window, and the inner sleeve has a distal end which cuts tissue as the inner sleeve is advanced past the window. The tissue is received into a lumen of the inner sleeve, and the inner sleeve lumen is typically enlarged in a proximal direction to reduce the tendency of resected tissue to lodge therein. The tissue displacement member is optionally provided at a distal end of the outer sleeve to further aid in dislodging tissue which becomes captured in a distal end of the inner sleeve of the lumen.

A protection circuit for a direct-current (DC) ablation prostate therapy system. The protection circuit is selectively coupled to a power source that provides DC constant current to a plurality of electrodes in a catheter configured to deliver DC ablation therapy to prostate tissue. The protection circuit is controlled by a controller and a switching circuit to buffer energy from the power source in response to a monitoring circuit that monitors at least one parameter of the DC ablation therapy, such as voltage or impedance. The controller is configured to selectively activate the switching circuit based on the monitoring circuit detecting an undesirable increase in the energy delivered for the DC ablation therapy.

The present disclosure relates to an electrosurgical instrument, configured to be releasably connected to a hand-piece. The electrosurgical instrument comprises an elongate shaft, an end effector at a distal end of the elongate shaft, and an electrical connector interface. The electrical connector interface has at least one female electrical socket configured to receive in use at least one male electrical pin of the hand-piece. Prior to first use, the at least one female electrical socket is sealed from an exterior of the electrosurgical instrument by a pierceable sealing layer. The sealing layer is configured to be pierced by the at least one male electrical pins on first use. A further aspect of the present disclosure relates to an electrosurgical system comprising the electrosurgical instrument, the hand-piece and an electrosurgical generator.

The present invention relates to an energy transmission module for a vaginal canal treatment apparatus, a method for controlling same, and a treatment method using same according to the present invention allow transmission of energy by means of insertion into the vaginal canal and expansion of the vaginal canal, and thus allow treatment by selectively or complexly generating denaturation such as coagulation and ablation over a large area in a short time, allow one-shot treatment, and allow treatment of an area with folds. Therefore, the efficiency and accuracy of the treatment can be enhanced. Since the tissue in the vaginal canal can be treated even without a surgical operation, user's pain and discomfort can be minimized.
