An apparatus for harvesting a vessel from a body, includes: a cannula having a dissector for advancing along the vessel to create a tunnel, the dissector having a transparent portion; and an energy tool moveably coupled to the cannula, wherein the energy tool is configured to separate a pediculated vessel having at least a segment of the vessel and a pedicle around the segment of the vessel from surrounding tissue, and wherein at least a part of the energy tool is visible through the transparent portion of the dissector during use of the energy tool.

A catheter for intraluminal lithotripsy including an outer wall, at least one balloon extending from the outer wall, the balloon having a first portion, a second portion proximal of the first portion and an intermediate portion between the first and second portions such that a transverse dimension of the intermediate portion is less than a transverse dimension of the first and second portions. The catheter includes a first lumen, at least one energy emitter mounted on the balloon for emitting energy to break down or soften calcium and a connector connecting the at least one energy emitter to an external energy source, the connector extending through the catheter.

Inflatable medical devices and methods for making and using the same are disclosed. The devices can be medical invasive balloons, such as those used for transcutaneous heart valve implantation, such as balloons used for transcatheter aortic-valve implantation. The balloons can have high strength, fiber-reinforced walls.

Systems and methods for tumor ablation with controlled precision of a temperature profile utilizing a tumor ablation probe device may include disposing a distal end of the tumor ablation probe device in a tissue, the distal end including a plurality of electrothermal modules (ETMs) on probe arm(s), each ETM including a first surface component electrically connected to a second surface component; supplying a first voltage of a first polarity or a second voltage of a second polarity to at least one ETM, and repeatedly alternating between the first polarity and the second polarity based on a time sequence cycle. When the first polarity is supplied, the ETM heats the first surface component and cools the second surface component, and when the second polarity is supplied, the ETM cools the first surface component and heats the second surface component. Each ETM and/or probe arm is configured for independent control.

A treatment energy application structure includes a flexible substrate having an electric resistance pattern and a lead wire connection portion. A heat transfer plate faces the flexible substrate and transfers heat to the body tissue. An insulating adhesive sheet is interposed between the flexible substrate and the heat transfer plate. The insulating adhesive sheet comprises a first area to cover an entire surface of the electric resistance pattern and the heat transfer plate and a second area protruding from the heat transfer plate to cover a part of the lead wire connection portion. The heat transfer plate has a chamfered corner facing the insulating adhesive sheet. An adhesive may adhere the second area to at least one of the heat transfer plate and the substrate. The insulating adhesive sheet may adhere the substrate to both the heat transfer plate and the bridge portion of a cover.

Devices and methods are provided for inhibiting mouth breathing and/or improving nasal breathing, e.g., for PAP users or users with other sleeping problems. In an exemplary embodiment, an adhesive device is provided that includes an elongate membrane comprising first and second ends and side edges extending between the first and second ends, a first surface comprising an adhesive layer. The adhesive layer may be a low tack adhesive that is adherent to skin, yet is also easily removable without leaving significant residue. Optionally, the device may include one or more valves to provide one-way flow across the membrane, one or more weakened regions in the membrane, and/or one or more tabs to facilitate removal of the membrane from over a user's mouth.

A surgical instrument includes a shell having a housing and a shaft. The shell including first and second shell components configured to engage one another to form the shell, each of which is monolithically formed to include a housing portion and a shaft portion. Upon engagement of the first and second shell components with one another, the housing portions cooperate to form the housing of the shell while the shaft portions cooperate to form the shaft of the shell. An end effector assembly is operably coupled to the shaft at a distal end of the shaft. A handle assembly is operably coupled to the housing. A drive assembly disposed within the shell is operably coupled between the handle assembly and the end effector assembly such that actuation of the handle assembly manipulates the end effector assembly.

A catheter including an elongated shaft having a distal end and a proximal end, where the catheter includes a thermal element at the distal end thereof. The thermal element may be used in an ablation procedure or other procedure to heat a tissue adjacent a vessel. In some instances, the thermal element may be positioned in a first vessel and may operate to heat tissue adjacent a second vessel or adjacent an ostium between the first vessel and the second vessel. Further, the catheter may include an expandable portion on which the thermal element may be connected or positioned. The expandable portion(s) may comprise a basket or cage, a balloon, a memory shape and formable portion, and/or to other mechanical expanders.

Tissue treatment systems include an actuator handle assembly coupled with a clamp assembly having a first jaw mechanism and a second jaw mechanism. A first jaw mechanism includes a first flexible boot, a first flexible ablation member coupled with the first flexible boot, and a first rotatable jawbone disposed within the first flexible boot. A second jaw mechanism comprises a second flexible boot, a second flexible ablation member coupled with the second flexible boot, and a second rotatable jawbone disposed within the second flexible boot.
