Embodiments include devices and methods configured to fractionally resect skin and/or fat. Fractional resection is applied as a stand-alone procedure in anatomical areas that are off-limits to conventional plastic surgery due to the poor tradeoff between the visibility of the incisional scar and amount of enhancement obtained. Fractional resection is also applied as an adjunct to established plastic surgery procedures such as liposuction, and is employed to significantly reduce the length of incisions required for a particular application. The shortening of incisions has application in both the aesthetic and reconstructive realms of plastic surgery.

A medical device includes an elongated sleeve having a longitudinal axis, a proximal end and a distal end. A cutting member having a plurality of sharp edges is formed from a wear-resistant ceramic material is carried at the distal end of the elongated sleeve. A motor drive is coupled to the proximal end of the elongated sleeve to rotate the sleeve at cutting member at high RPMs to cut bone and other hard tissue. An electrode is carried in a distal portion of ceramic cutting member for RF ablation of tissue when the sleeve and cutting member are is a stationary position. In methods of use, (i) the ceramic member can be engaged against bone and then rotated at high speed to cut bone tissue, and (ii) the ceramic member can be held in a stationary (non-rotating) position to engage tissue and RF energy can be delivered to the electrode to create a plasma that ablates tissue.

A kit for removing a tissue lesion includes an anchor for securing a tissue lesion, incision blades for creating an incision in tissue, a tissue resection device for creating a tissue core that includes the tissue lesion and a tissue dilator to help open a channel of sufficient volume to receive the tissue resection device. The tissue resection penetrates tissue, creates a tissue core that includes the tissue lesion and seals and dissects the tissue lesion from surrounding tissue.

A sheath adapter may be used within a medical device to provide one or more additional lumens. One sheath for use with a medical device may comprise a C-shaped elongate shaft extending from a proximal end to a distal end, the C-shaped elongate shaft configured to fit onto a shaft of the medical device and a lumen extending at least partially along a length of the elongate shaft, the lumen having a first port disposed proximate the distal end of the C-shaped elongate shaft and a second port disposed proximate the proximal end of the C-shaped elongate shaft.

Systems, devices, and methods for fluid management in an endoscopic procedure are disclosed. In one embodiment, a fluid management device may comprise a pair of electrodes and a controller connected to the pair of electrodes. In at least some embodiments, the controller may be configured to receive signals from the pair of electrodes and determine whether a fluid in a fluid reservoir is an ionic fluid or a non-ionic fluid based on signals received from the pair of electrodes. In at least some additional embodiments, the controller may be further configured to automatically set a fluid deficit alarm threshold based on the determination of whether the fluid in the fluid reservoir is an ionic fluid or a non-ionic fluid.

A desiccation device for operation on a target tissue includes a handle, a shaft extending distally from the handle, and a head. The shaft defines a lumen therethrough, and the head has a loop configuration supported on a distal end of the shaft. The head is hollow and defines a lumen therethrough. The lumen of the head is in fluid communication with the lumen of the shaft. At least a portion of the head is electrically connected to a source of electrosurgical energy. A fluid is circulatable through the lumens of the shaft and the head.

Provided is a digestive-tract treatment method including: pulling, inside a digestive tract (A), an end portion of a first wall portion (A1) positioned at a rim of a treatment target site (B), and moving the first wall portion (A1) to a position on a second wall portion (A2) on an opposite side of the treatment target site (B) from the first wall portion (A1); and joining the first wall portion (A1) and the second wall portion (A2) in a state in which the first wall portion (A1) and the second wall portion (A2) are layered.

Surgical tool can include an outer shaft, a guide, an end effector, and a drive shaft. The outer shaft can extend along a longitudinal axis. The guide can be connected to the outer shaft. The end effector can include a first jaw connected to the outer shaft distal of the guide and a second jaw pivotably connected to the outer shaft distal of the guide. The drive shaft can be located within the outer shaft and can extend along the longitudinal axis. The drive shaft can be connected to the end effector and the drive shaft can be engageable with the guide to limit movement of the drive shaft with respect to the outer shaft in a direction not parallel with the guide. The drive shaft can be translatable along the outer shaft to operate the end effector.

An ablation system includes a retractable sheath including a lumen; a first electrode in the lumen; a pre-bent telescopic tube extendable from the lumen and including a second electrode, wherein the first electrode and the second electrode are configured to deliver an electric field energy to target tissue in a patient.

A forceps having a first jaw and a second jaw, where at least one of the first and second jaws is capable of moving between an open position and a closed position. The forceps including an inner shaft located within an outer shaft and extending along the longitudinal axis, and a drive bar coupled to and extending distally from the inner shaft. The drive bar including a pair of drive bar struts extending from a distal portion of the inner shaft and positioned laterally inward of at least one of first and second set of flanges of the first and second jaws. A drive pin is securable to the pair of drive bar struts and the drive bar is translatable within the outer shaft to translate the drive pin to move the first jaw and/or the second jaw between open and closed positions.
