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.

Tumor treating fields (TTFields) can be delivered by implanting a plurality of sets of implantable electrode elements within a person's body. Temperature sensors positioned to measure the temperature at the electrode elements are also implanted, along with a circuit that collects temperature measurements from the temperature sensors. In some embodiments, an AC voltage generator configured to apply an AC voltage across the plurality of sets of electrode elements is also implanted within the person's body.

In one aspect, embodiments relate to a system for preventative dental laser treatment that ensures even irradiation of a laser beam. The system includes, a laser arrangement configured to generate the laser beam. The laser beam has one or more of a super-Gaussian energy profile and a transverse ring mode. The system also includes a focus optic. The focus optic is configured to converge the laser beam with a numerical aperture of 0.1 or less to a focal region. The system also includes a hand piece configured to direct the laser beam at a surface of a dental hard tissue. The system additionally includes a controller. The controller is configured to control one or more parameters of the laser source, such that a portion of the surface of the dental hard tissue is heated to a temperature in a range between 400° Celsius and 1300° Celsius.

An unattended approach can increase the reproducibility and safety of the treatment as the chance of over/under treating of a certain area is significantly decreased. On the other hand, unattended treatment of uneven or rugged areas can be challenging in terms of maintaining proper distance or contact with the treated tissue, mostly on areas which tend to differ from patient to patient (e.g. facial area). Delivering energy via a system of active elements embedded in a flexible pad adhesively attached to the skin offers a possible solution. The unattended approach may include delivering of multiple energies to enhance a visual appearance.

Methods and systems that provide quantitative assessments of in vivo thermal treatments, such as ablations, during image-guided surgeries using a high-resolution pre-operative MRI image segmented with a shape constrained and deformable mesh representations of brain structures and generating 3-D visualizations of thermally treated volumes during the thermal treatment that can provide near real time visual and quantitative feedback to a clinician.

The present disclosure is directed to tools, systems and methods for recontouring/reshaping gum tissue by engaging a consumable tip on a powered tool to abrade/ablate excess or mal-contoured gum tissue to allow better visualization of the tooth/implant structure and reduce the periodontal pockets to provide improved access for cleaning by both the patient and clinician. In some embodiments, the powered tool may use vibrational movement, longitudinal reciprocating movement, rotational movement, reciprocating rotational movement, or a combination of any of the above movement schemes. In some embodiments, a consumable tip may be directed for cleaning tooth/implant surfaces and for recontouring/reshaping gum tissue. The powered tool itself may be constructed to allow the cooling water flow used for operation to be directed to the site where the procedure is carried out for irrigation or to be directed elsewhere at the user's selection to facilitate gum contouring procedures.

Disclosed are a dental disease treating device, and more particularly, to a dental disease treating device that may generate high-density plasma that is required for a treatment of a dental disease, such as periodontitis, and minimize generation of ozone as well, and a method for treating a dental disease. The dental disease treating device that generates plasma for treating a dental disease, includes a handpiece body having a space part in an interior thereof, a plasma generating part mounted in the space part of the handpiece body, and that generates the plasma by exciting a gas in a plasma generating space in an interior thereof, and a tip part detachably coupled to an end nozzle of the handpiece body or the plasma generating part, and the tip part includes a passage for irradiating the plasma to a local portion while inhibiting oxygen from being introduced into the plasma generating space.

Described herein is a method of treating migraines using PFA ablation technology which includes advancing a pulse field ablation delivery member into a nasal cavity (both unilateral and bilateral) of a patient with the pulse field ablation member in a first collapsed configuration and contacting a surface of a nasal cavity tissue with the pulse field ablation delivery member without penetrating or piercing the nasal cavity tissue surface. The treatment further includes reconfiguring the pulse field ablation delivery member from the first collapsed configuration to an expanded configuration after introducing the pulse field ablation member into the desired position within the nasal cavity, and ablating a target treatment site with the pulse field ablation delivery member in order to treat or prevent at least one of the group of medical conditions, wherein the target treatment site includes at least one nasal nerve tissue or nasal blood vessel with or without contact.

An ablation probe tip 100 having a shaft 102 with an insertion end 104 and an annular aperture 120 near the insertion end 104. A center of ablation 124 is located within the shaft 102 and surrounded by the annular aperture shaft 102. The ablation probe tip 100 may be part of an ablation probe system 50 that includes an ablation source 60 that provides ablation means 62 to the ablation probe tip 100. The center of ablation 124 is a focal region from which the ablation means 62 radiates through the annular aperture 120 to form an ablation zone 150, 160, 170. The system 50 has at least one intra-operative control selected from the group of: ablation zone positioning control, ablation zone shaping control, ablation center control, ablation zone temperature control, guided ablation volume/diameter control, and power loading control.

An elongate electrode is configured to flex and generate plasma to incise tissue. An electrical energy source operatively coupled to the electrode is configured to provide electrical energy to the electrode to generate the plasma. A tensioning element is operatively coupled to the elongate electrode. The tensioning element can be configured to provide tension to the elongate electrode to allow the elongate electrode to flex in response to the elongate electrode engaging the tissue and generating the plasma. The tensioning element operatively coupled to the flexible elongate electrode may allow for the use of a small diameter electrode, such as a 5 μm to 20 μm diameter electrode, which can allow narrow incisions to be formed with decreased tissue damage. In some embodiments, the tensioning of the electrode allows the electrode to more accurately incise tissue by decreasing variations in the position of the electrode along the incision path.
