摘要： A control unit controls delivery of RF energy generated by an RF generator to a medical device configured to perform a medical procedure. The control unit may be separate from the RF generator, and may have an input that may be attached to an output of the RF generator. The control unit includes switching circuitry that is closed while an amount of RF energy is transmitted through the control unit to the medical device. The switching circuitry opens when the amount of RF energy reaches a threshold level.

摘要： An electrosurgical device and a method of orienting the electrosurgical device are provided. The device includes a rotation mechanism including a first and a second connector where the first connector is rotatable relative to the second connector. The device also includes a handle operably connected to the first connector; and a catheter operably connected to the second connector where the handle is rotatable relative to the catheter. The device further includes a first wire having a distal portion anchored to a distal portion of the catheter so that the distal portion of the wire is orientable by rotation of the handle relative to the catheter. At least one of the rotation mechanism or a proximal portion of the wire forms a conductive connection that operably connects a power source to the distal portion of the first wire to energize the distal portion of the first wire in the electrosurgical device.

摘要： A bipolar sphincterotome may include an elongate tubular member, a cutting wire, and a return path. The return path may include a conductive ink portion disposed on an outer surface at a distal portion of the tubular member. The return path may also include a return wire disposed within the tubular member that is electrically coupled to the conductive ink portion. In some example embodiments, the return wire may be disposed within a lumen configured to have two or more functions, one of which being to house the return wire. Additionally, in some example embodiments, the conductive ink portion may be circumferentially disposed on the outer surface to provide visual access to a wire guide lumen. Also, for some example embodiments, the bipolar sphincterotome may include two electrically isolated return paths.

摘要： A valve insertion device for traversing a wire guide through a valve within an intraluminal passage. A wire guide is positioned near the outflow of a valve within an intraluminal passage. Alongside the wire guide, a pressure sensor is positioned to detect the pressure of the fluid in the intraluminal passage. As the valve opens, the fluid pressure at the outflow of the valve increases. This information is sent from the pressure sensor to a control system. From this information, the control system can determine when the valve will open and can actuate an advancement system to move the wire guide to traverse the open valve. After traversing the valve, various catheters and sheaths may be advanced over the wire guide through the valve.
