The present invention is directed to personal heating devices, known as heated packs. Heated packs of the invention include a frame and a heating assembly disposed within the frame. The heating assembly may include a heating panel, an intelligent circuit, and a battery. In certain embodiments, one or more sides of the frame include a material configured to absorb heat or release heat in response to the energy outputted by the heating assembly. In further embodiments, the intelligent circuit is configured to change the temperature of the heating pack based a sensory input received by a user.

A multi-pole synchronous pulmonary artery radiofrequency ablation catheter may comprise a control handle, a catheter body and an annular ring. One end of the catheter body may be flexible, and the flexible end of the catheter body may be connected to the annular ring. The other end of the catheter body may be connected to the control handle. A shape memory wire may be arranged in the annular ring. One end of the shape memory wire may extend to an end of the annular ring and the other end of the shape memory wire may pass through a root of the annular ring and be fixed on the flexible end of the catheter body. The annular ring may be provided with an electrode group. The device possesses advantages of simple operation, short operation time and controllable precise ablation. The device can be used to treat pulmonary hypertension with pulmonary denervation.

A suction and irrigation apparatus includes: a handle having a mounting space therein; an insertion unit extending from the handle and inserted into a patient's abdominal cavity; and a suction and supply unit disposed in the mounting space and supplying an irrigation fluid to the insertion unit or suctioning blood or other contaminated fluids from the patient's abdominal cavity through the insertion unit.

A radiofrequency ablation catheter having a meshed tubular stent structure and an apparatus thereof, include a meshed tubular stent disposed at a front end of the catheter. The meshed tubular stent comprises and including a meshed tube (1). Both ends of the meshed tube are tapered to form a distal end and a proximal end of the meshed tubular stent. The intermediate segment of the meshed tubular stent has a contracted state and an expanded state. One or more electrodes (2) are fixed onto the intermediate segment. The radiofrequency ablation catheter has improved flexibility and provides great coverage for the blood vessels with different thicknesses and curves. When the meshed tubular stent expands in the blood vessels having different thicknesses of 4-12 mm, all of the electrodes (2) contact the walls. Moreover, when the meshed tubular stent expands in the curved blood vessels, all of the electrodes are ensured to contact the walls.

A surgical tool that includes a sterilzable handpiece that receives an aseptic power module. The handpiece includes a data tag that contains data identifying the type of handpiece. The power module includes a reader that reads the data from the data tag. Based on the type of handpiece the power module selectively actuates the power generating unit internal to the power module. Specifically, the power generating unit is actuated to output energy having the appropriate characteristics for the type of handpiece to which the power module is attached. In many versions of the invention, the data tag is mounted to the latch integral with the handpiece. The power module also interprets the receipt of the data from the handpiece as an indication that the power module is properly latched into the handpiece.

A bipolar tunneling tool is configured to separate tissue adhesions and tunnel. The bipolar tunneling tool includes a handle, a tunneling shaft, a return electrode, an optical window, an active electrode, and an insulative housing. The tunneling shaft extends from the handle. The return electrode is disposed proximate a distal end of the tunneling shaft. The optical window is disposed proximate the distal end of the tunneling shaft, the optical window defining a channel. The active electrode is at least partially disposed within the channel. The active electrode is configured to dissect a tissue and cauterize the tissue. The insulative housing is configured to electrically insulate the active electrode from the return electrode.

An ablation device includes a feedline including an inner conductor having a distal end, an outer conductor coaxially disposed around the inner conductor, and a dielectric material disposed therebetween, an elongated electrically-conductive member longitudinally disposed at the distal end of the inner conductor and having a proximal end, a first balun structure disposed over a first portion of the outer conductor and positioned so that a distal end of the first balun structure is located at a first distance from the proximal end of the electrically-conductive member and a second balun structure disposed over a second portion of the outer conductor and positioned so that a distal end of the second balun structure is located at a second distance from the proximal end of the electrically-conductive member.

An ultrasonic instrument includes a body, an actuation assembly, a shaft assembly, and an end effector. The actuation assembly includes an activation member that is operable to move in a first direction to select a mode of operation. The shaft assembly extends distally from the body and includes an acoustic waveguide. The end effector includes an ultrasonic blade that is in acoustic communication with the acoustic waveguide. The activation member is operable to move in a second direction to activate the end effector in a mode of operation selected by movement of the activation member in the first direction.

A therapeutic treatment device including: a heat conduction plate including a first major surface and a second major surface opposite to each other and configured to apply heat to a living tissue, with the first major surface kept in contact with the living tissue; an electric resistance pattern formed on an insulative substrate and configured to generate heat upon application of power; and an adhesive sheet which adheres the second major surface of the heat conduction plate and the electric resistance pattern to each other and is configured to transfer the heat generated by the electric resistance pattern to the heat conduction plate.
