An energy treatment instrument includes: an insertion section, first and second probes, an output section, and an adjuster. The first and second probes are provided on a distal side along the longitudinal axis of the insertion section. The output section is provided on each of the first and second probes, and is configured to output energy to an outside of the first and second probes when supplied with energy. The adjuster is configured to move the first probe in an extending direction of the first probe and to move the second probe in an extending direction of the second probe with an amount of movement which is different from an amount of movement of the first probe, so as to adjust positions of end portions of the first probe and the second probe.

An energy treatment instrument includes: an insertion section, a base, a needle section, an output section, and a cover portion. The needle section includes a tip end projecting in a first direction relative to the base. The output section is configured to output energy to an outside of the needle section when supplied with energy. The cover portion includes an end portion which is movable relative to the base. The cover portion is configured to move between a first position and a second position. In the first position, the cover portion is configured to protect the tip end of the needle section and the output section. In the second position, the end portion of the cover portion is evacuated from the tip end of the needle section and the output section.

The present disclosure is directed to a surgical device and method of using the same. The surgical device includes a proximal ring, a distal ring, wherein the distal ring is operably connected to the proximal ring with a sleeve, the sleeve extending about a circumference of the proximal ring and a circumference of the distal ring, a film, a distal end of the film attached to a portion of the distal ring, wherein the film is configured to extend past the sleeve and past the distal ring, and wherein a proximal portion of the film comprises an opening and a channel and a draw string extending through the channel and exposed to an exterior of the device through the opening.

An apparatus for mechanically manipulating hollow organs within the body of a subject, or an organ manipulation apparatus, includes a manipulation section. The manipulation section may include a substantially two-dimensional element, which may have a width that exceeds a distance across a portion of the interior of a hollow organ within which the manipulation section is to be positioned. The manipulation section is configured to manipulate at least a portion of a hollow organ from within, which may modify at least one of a shape, orientation, or location of at least part of the hollow organ.

Methods for manipulating hollow organs are also disclosed, as are operating techniques, such as left atrial ablation, in which the shapes, orientations, and/or locations of hollow organs are manipulated to move the hollow organs away from the site of the medical procedure, reducing the potential for damage to the hollow organs.

In an endoscopic treatment method, a damaged area is formed in a digestive tract at least a portion in a circumferential direction of the digestive tract, the damaged area being formed by ablating mucosal layer while remaining the mucosal layer, and an incomplete stenosis is formed in the digestive tract, during performance of a process of restoration of the damaged area.

A treatment of obstructive lung disease includes aiming a condensable vapor towards the airway wall, causing a band-shaped lesion to grow to a depth into the airway wall. Ablation parameters are set to control the depth of the band-shaped lesion to encompass the epithelial layer and exclude the smooth muscle layer of the airway. A wide variety of configurations of the vapor delivery are described to create ablation patterns in the airways of the patient with particular emphasis on treating chronic bronchitis.

An injection needle has an opening at a distal end thereof the injection needle and defines a hole. An optical fiber is configured to output a light from a light source and inserted in the hole. The optical fiber has a distal end positioned on an inner side of the opening. A protector is configured to transmit the light and is positioned further towards an opening side of the injection needle than the distal end. The protector is configured to prevent adherence of tissue to the optical fiber. The light emitted from the optical fiber is configured to irradiated onto a treatment target in a state in which the injection needle is inserted into skin, the distal end is positioned on an inner side of the opening, and the protector is positioned further towards the opening side of the injection needle than the distal end.

A positioning device is configured to selectively position or otherwise manipulate one or more organs within the body of a subject. The positioning device includes a shaped expandable element that is configured to be selectively transitioned between an unexpanded, or collapsed, state and an expanded state. While in the expanded state, the expandable element repositions or otherwise manipulates an organ. Systems that include positioning devices are also disclosed, as are methods for positioning or otherwise manipulating organs.

Bone fusion system, plate system, guide, implant, kit and methods for using the bone fusion system, plate system, guide and implant are disclosed. The bone fusion system includes an alignment guide, an implant, and at least one fastener inserted through the implant. The alignment guide includes a body portion, a first lobe positioned at a first end of the body portion, a second lobe positioned at a second end of the body portion, and an extension member extending away from a first side of the body portion. The implant includes a body portion, a first arm extending away from the body portion in a first direction, a second arm extending away from the body portion in a second direction, and a third arm extending away from the body portion laterally between first and second arms. Finally, methods for using the bone fusion system, plate system, guide and implant are disclosed.
