A surgical instrument that includes a surgical end effector that is articulatable relative to a proximal shaft segment of the surgical instrument. The surgical end effector is attached to the proximal shaft segment by an articulation joint that comprises a plurality of movably interconnected links that interface with a centrally disposed drive member to apply articulation motions thereto and which serve to provide improved lateral stability to the articulation joint.

The disclosure includes a vein ablation system, comprising a catheter having an elongated body. In some embodiments, the vein ablation system comprises an ablation device at a distal portion of the elongated body. According to some embodiments, the vein ablation system comprises a control device at a proximal portion of the elongated body. The control device may comprise an input mechanism configured to simultaneously control at least two of a longitudinal translation of the ablation device through a target vessel, a rotation of the ablation device about a central longitudinal axis, and an infusion of a chemical agent into the target vessel.

Disclosed herein are systems and methods for locating and identifying nerves innervating the wall of arteries such as the renal artery. The present invention identifies areas on vessel walls that are innervated with nerves; provides indication on whether energy is delivered accurately to a targeted nerve; and provides immediate post-procedural assessment of the effect of energy delivered to the nerve. The methods includes evaluating a change in physiological parameters after energy is delivered to an arterial wall; and determining the type of nerve that the energy was directed to (sympathetic or parasympathetic or none) based on the evaluated results. The system includes at least a device for delivering energy to the wall of blood vessel; sensors for detecting physiological signals from a subject; and indicators to display results obtained using said method. Also provided are catheters for performing the mapping and ablating functions.

Provided is a scissors-type medical treatment tool capable of not only local tissue fixation in an incision/cutting part but also heating on side surfaces of electrodes of a forceps/tweezers type. It has been found out that a tissue part in which tissue is nipped between blades and a tissue part which is brought into abutment against side surfaces of the blades can be heated simultaneously or sequentially by optimizing arrangement of microwave application electrodes and microwave receiver electrodes in a blade pair (in particular, by causing coagulation to be performed evenly on the left and right of the blades), and the present invention has therefore been achieved.

A radio-frequency ablation catheter comprises a handle having a proximal end and a distal end, an outer tube assembly having a proximal end and a distal end, and an inner tube assembly having a proximal end and a distal end; the proximal end of the outer tube assembly is connected to the distal end of the handle; the proximal end of the inner tube assembly is connected to the distal end of the handle; the inner tube assembly can be driven by the handle to rotate relative to the outer tube assembly; the inner tube assembly comprises a branch electrode assembly, and the branch electrode assembly comprises a plurality of branch electrodes distributed at intervals in the circumferential direction. The branch electrode assembly of the radio-frequency ablation catheter and the radio-frequency ablation system can rotate relative to the outer tube assembly to avoid blood vessels.

The subject of this disclosure is devices, systems, and uses thereof to treat a plurality of patients for paroxysmal atrial fibrillation. The solution can include delivering a multi-electrode radiofrequency balloon catheter and a multi-electrode diagnostic catheter to one or more targeted pulmonary veins; ablating tissue of the one or more targeted pulmonary veins using the multi-electrode radiofrequency balloon catheter; diagnosing the one or more targeted pulmonary veins using the multi-electrode diagnostic catheter; and achieving at least one of a predetermined clinical effectiveness and acute effectiveness of the method or use based on use of the multi-electrode radiofrequency balloon catheter and the multi-electrode diagnostic catheter in the isolation of the one or more targeted pulmonary veins.

An energy-delivery device (10) includes a handle body (12), an antenna assembly (14) extending distally from the handle body (12), and a transmission line (16) configured to be detachably coupled to the antenna assembly (14).

Provided herein is a multifunctional aesthetic system including a housing, an electromagnetic array situated in the housing and having one or more electromagnetic radiation (EMR) sources, a controller in electronic communication with the array to operate the one or more of the EMR sources to direct the EMR beam to a treatment area, and one or more sensors in electronic communication with the controller for providing feedback to the controller based on defined parameters to allow the controller to adjust at least one operating condition of the multifunctional system in response to the feedback.

Disclosed is a plasma skin care device including a handpiece, an ozone decomposition module, and a suction fan. The handpiece has a plasma generator and discharges plasma in a state in which a front end portion of the plasma generator is adjacent to skin. The ozone decomposition module is configured to receive and decompose ozone, which is generated when the plasma is discharged, from the handpiece. The suction fan is configured to draw the ozone generated in the handpiece to the ozone decomposition module by suction pressure.

An ablation device includes a first jaw, a second jaw including an ablation unit including a protrusion for ablating a tissue and being rotatable with respect to the first jaw under the first jaw, and a signal unit configured to provide a signal to the tissue and receive a reflected signal and disposed on the second jaw, in which the signal unit moves in a longitudinal direction of the ablation unit, the first jaw does not overlap the signal unit in a vertical direction, and the second jaw overlaps the signal unit in the vertical direction.
