Apparatus for performing a minimally-invasive procedure, the apparatus comprising: a shaft having a distal end and a proximal end; a monopolar knife assembly attached to the distal end of the shaft, the monopolar knife assembly comprising a knife; a handle attached to the proximal end of the shaft; wherein the shaft comprises a flexible portion and an articulating portion, wherein the flexible portion extends distally from the handle and the articulating portion extends distally from the flexible portion; wherein at least one articulation cable extends from the handle to the articulating portion, such that when tension is applied to the at least one articulation cable, the articulating portion deflects; wherein an actuation element extends through the shaft from the handle to the knife, such that when the actuation element is moved, the knife is moved; and wherein the actuation element transmits electrical power from the handle to the knife.

Various catheters are provided herein for recording, mapping, and/or ablating target tissue to reduce or eliminate unwanted electrical impulses. In one embodiment, a catheter can have a handle, an elongate body, and an end effector. The end effector has expanded and contracted configurations and can rotate about the elongate body. A plurality of electrodes can also be disposed on the end effector for recording, mapping, and/or ablating target tissue surrounding the catheter. The handle can guide the end effector through transitioning between the configurations and rotating about the elongate body.

Embodiments of the inventive concept provide an ultrasonic medical instrument moving horizontally by adjusting a depth wise location of an ultrasonic wave generating unit while not influencing an internal volume of a cartridge and variously setting focusing depths of ultrasonic waves in skin.

Present disclosure provides a cooling device with safety features and methods for controlling temperature of the cooling device for safe cooling of target surface.

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.

A surgical instrument which is configured to be releasably connected to a hand-piece is disclosed. The surgical instrument includes an elongate shaft, an end effector at a distal end of the elongate shaft, and a connection hub at a proximal end of the elongate shaft. The connection hub includes a moveable member moveable relative to the elongate shaft. The moveable member is configured to be switchable between an on position and an off position. During insertion of the surgical instrument into the hand-piece, an electrical connection therebetween is prevented by the connection hub when the moveable member is in the on position.

A surgical instrument including a housing, an actuator operably associated with the housing, a shaft extending from the housing, an end effector assembly disposed at an end portion of the shaft, and a drive assembly operably coupling the actuator and the end effector assembly with one another such that actuation of the actuator manipulates the end effector assembly. The drive assembly includes a proximal sleeve defining a longitudinal axis and an interior lumen extending longitudinally therethrough, a drive bar including a proximal portion and a distal portion, and a lock washer configured to engage the proximal portion of the drive bar with the proximal sleeve such that the proximal portion of the drive bar is disposed within the interior lumen of the proximal sleeve and positioned offset relative to the longitudinal axis of the proximal sleeve. Methods of assembling such drive assemblies are also provided.

Methods of assembling a medical device including pivotably connecting a coupling link to a first lever. The coupling link including a main body and a tab extending away from the main body. The first lever having a first pivot and a boss. The method further including nesting the first lever and the coupling link with a second lever such that a recess in the second lever is supported by the boss, and such that an inner surface of the second lever is supported by the coupling link to provide a portion of the medical device in a sub-assembled state.

A device or scope device is disclosed. The device may comprise: a handle body extending along an axis between first end and a second end; an actuator at the first end of the handle body; a catheter at the second end of the handle body; and a processing unit communicable with a plurality of devices to: switch-in the actuator for control of one device of the plurality of devices; configure, with the actuator, a setting of the one device, control, with the actuator, the one device based on the setting, and switch-in the actuator for control of another one of the plurality of devices. Related devices and methods also are disclosed.
