A method of surgery includes determining a target zone of tissue, adjusting settings of a treatment device based on the target zone of tissue, positioning the treatment device adjacent the target zone of tissue, deploying the treatment device such that the treatment device defines a deployed configuration in accordance with the settings, and treating the target zone of tissue using the treatment device. An ablation system includes a housing, an elongated body extending distally from the housing, and a plurality of probes deployable from the elongated body. At least one control is configured to adjust settings associated with at least one probe such that, upon deployment of the plurality of probes, the plurality of probes define a deployed configuration in accordance with the settings.

Prostate treatment using fluid stream to resect prostate tissue, thereby relieving symptoms of conditions such as BPH, prostatitis, and prostatic carcinoma. A device having a fluid delivery element is positioned within a lumen of the urethra within the prostate. A fluid stream is directed outwardly from the fluid delivery element toward a wall of the urethral lumen. The fluid delivery element is moved to scan the fluid stream over the wall to remove a volume of tissue surrounding the lumen. The fluid may be combined with therapeutically active substances or with substances that increase resection efficiency. Fluid force may be adjusted to provide selective tissue resection such that soft tissue is removed while harder tissue is left undamaged. In order to gain a working space within the urethra, another fluid may be introduced to insufflate the urethra in the region of treatment.

The disclosure provides a method of manufacturing a flexible circuit electrode assembly and an apparatus manufactured by said method. According to the method, an electrically conductive sheet is laminated to an electrically insulative sheet. An electrode is formed on the electrically conductive sheet. An electrically insulative layer is formed on a tissue contacting surface of the electrode. The individual electrodes are separated from the laminated electrically insulative sheet and the electrically conductive sheet. In another method, a flexible circuit is vacuum formed to create a desired profile. The vacuum formed flexible circuit is trimmed. The trimmed vacuum formed flexible circuit is attached to a jaw member of a clamp jaw assembly.

A control handle for a steerable catheter allows for precise manipulation of the distal catheter tip in a target organ or vessel using only one hand. The control handle can have a single articulating knob capable of both linear translation along and rotation about the axis of the handle. These functions of the articulating knob actuate both the expansion and retraction of an expandable member, as well as bi-directional deflection of the distal catheter tip. The articulating knob functions with consistency regardless of the orientation of the handle, with ergonomic movements allowing the user to comfortably keep their attention on the procedure's monitoring equipment. These improvements can lead to safe and more rapid procedure times for procedures such as diagnostics and cardiac ablation.

A surgical forceps comprising: a first working arm and a second working arm configured to move towards and away from each other; and an electromagnetic latching system; wherein the electromagnetic latching system is configured to create a force that is in a direction aligned with closing of the forceps or opposite to the closing of the forceps when an electromagnetic activation button is depressed.

An electrosurgical instrument used in electrosurgery, and includes a handpiece to be gripped by a user and provided with an accommodation space therein; a cable coupled to a rear end of the handpiece so as to transmit electrical energy; a conductive electrode, at least a portion of which protrudes toward a front side of the handpiece and which is configured to move in a front-rear direction relative to the handpiece; and a connecting body provided in the accommodation space and including a conductor electrically connecting the cable and the conductive electrode to each other, and a film formed of a non-conductive material and bonded to opposite sides of the conductor so as to shield the conductor, wherein at least a portion of the connecting body is formed of a Flexible Printed Circuit Board (FPCB) and is formed in a spiral or helical shape such that the total length of the connecting body is variable in the front-rear direction. According to the present disclosure, it is possible to provide an electrosurgical instrument in which, since the connecting body is provided, an electrically stable coupling state can be ensured and the conductive electrode can be moved smoothly when the conductive electrode is moved in the front-rear direction relative to the handpiece or is rotated.

Provided is an endoscopic treatment instrument that can maintain a state where the treatment instrument protrudes, by a simple manipulation and that can keep an amount of protrusion of the treatment instrument constant. The endoscopic treatment instrument (1) has an operation unit having: an operation unit body (50) fixed to a cylindrical member; and a slider (60) that is fixed to a linear object and is slidable with respect to the operation unit body (50) in the longitudinal direction. The operation unit is provided with a first stop position and a first stop release position distal to the first stop position, the first stop position being a position where the operation unit body (50) and the slider (60) contact each other as a result of relative movement of the operation unit body (50) and the slider (60).

A surgical tool can include a handle, an outer tube, an end effector, an inner tube, and a guide tube. The outer tube can be connected to the handle and can extend along a longitudinal axis. The end effector can be connected to the outer tube. The inner shaft can be located within the outer tube and can extend along the longitudinal axis. The inner shaft can be connected to the end effector and the outer shaft. The handle can be operable to translate the inner shaft with respect to the outer tube to operate the end effector. The guide tube can be located within the outer tube between the handle and the end effector. The guide tube can include a conduit extending therethrough.

The invention generally relates to systems and methods for therapeutically modulating nerves in or associated with a nasal region of a patient for the treatment of a rhinosinusitis condition.

A medical device that is capable of reducing release of a state in which an energy transmission element is pressed against a biological tissue due to an erroneous operation or a malfunction of an operation unit. The medical device includes an expandable body, a shaft portion connected to the expandable body, an energy transmission element provided in the expandable body, a housing connected to a proximal end portion of the shaft portion, a displacement shaft configured to compress the expandable body in an axial direction, an operation knob configured to operate the displacement shaft that is movable from a first position to a third position via a second position, with respect to the housing, and a lock portion configured to lock the operation knob at the second position.
