Aspects described herein pertain to restoring damaged portions of tooth or bone using plasma mediated deposition. In an embodiment, a biocompatible carrier gas is ionized to form a biocompatible atmospheric plasma stream. Restoration material, such as nano-scale powdered hydroxyapatite, is introduced into the plasma stream, which is then applied to a damaged portion of a bone or tooth. The restoration material is deposited on the damaged portion of the bone or tooth, thus restoring a shape and mechanical integrity of the bone or tooth.

Devices and methods for tissue treatment produce a mechanical stimulation therapy and electromagnetic field therapy. The mechanical stimulation therapy provides stimulation of blood circulation and stimulates treated cells. The electromagnetic field enables thermal treatment of tissue. Combination of both therapies improves soft tissue treatment, mainly connective tissue in the skin area and fat reduction.

The invention relates to a treatment device for dielectric harrier discharge plasma treatment of a wound surface or skin surface, having: a flexible, planar electrode assembly with at least one planar electrode (6, 6′) and a dielectric layer (5) which at least partially embeds the at least one electrode (6, 6′), has a contact side (7) facing the wound surface or skin surface and electrically shields the planar electrode (6, 6′) from the wound surface or skin surface such that only a dielectric barrier current can flow from the electrode (6, 6′) to the wound surface or skin surface; and a control device (2) which has a separate housing (25) and via which the electrode (6, 6′) can be connected to an operating voltage. The treatment device allows simpler wound treatment in that the assembly of electrode (6, 6′) and dielectric layer (5) is designed for uninterrupted contact with the wound surface or skin surface and that the housing (25) of the control device (2) can be fastened with a fastening device (3, 3′) to the body having the wound surface or skin surface.

A method of analysis using mass spectrometry and/or ion mobility spectrometry is disclosed. The method comprises: using a first device to generate smoke, aerosol or vapour from a target comprising or consisting of a microbial population; mass analysing and/or ion mobility analysing said smoke, aerosol or vapour, or ions derived therefrom, in order to obtain spectrometric data; and analysing said spectrometric data in order to analyse said microbial population.

A device for ablating target tissue of a patient with electrical energy is provided. An elongate shaft includes a proximal portion and a distal portion, and a radially expandable element is attached to the distal portion. An ablation element for delivering electrical energy to target tissue is mounted to the radially expandable element. The device can be constructed and arranged to ablate the duodenal mucosa of a patient while avoiding damage to the duodenal adventitial tissue. Systems and methods of treating target tissue are also provided.

According to an aspect, there is provided a system (40) configured to perform a personal care operation on skin of a subject. The system (40) comprises a processing unit (46) and a personal care device (2). The personal care device (2) comprises a housing (4) having an aperture (10) that is arranged in the housing (4) such that the aperture (10) is adjacent to the skin when the personal care device (2) is in contact with the skin and is to be used to perform the personal care operation on the skin. The personal care device (2) also comprises an imaging unit (44) disposed in the housing (4) and arranged to obtain images of the skin adjacent to the aperture (10) using light passing through the aperture (10) into the personal care device (2), wherein, in a skin contact detection mode of the system (40), a focal plane (66) of the imaging unit (44) is aligned with the aperture (10). The processing unit (46) is configured to receive, in the skin contact detection mode, one or more images obtained by the imaging unit (44) in the skin contact detection mode, and to process the one or more images to determine whether the personal care device (2) is in contact with the skin.

An instrument test arrangement is specified, which is preferably equipped for medical instruments for argon plasma coagulation. The instrument test arrangement comprises an electrode arrangement, comprising at least one test electrode. In a preferred embodiment, a test electrode is thereby connected to two neutral conductors of a neutral conductor cable or device, wherein the neutral conductors are insulated from one another, and wherein the first coupling impedance between the test electrode and the first neutral conductor and the second coupling impedance between the test electrode and the second neutral conductor are equal or at most slightly different, so that a split circuit, which is assigned to a neutral electrode arrangement, does not trigger due to the strike of a test spark or arc.

An apparatus (14) for supplying a medical instrument (15) for the treatment of biological tissue (11) due to the action of a plasma (28) is disposed, in accordance with the invention, in a special manner for the ignition and the stable development of a plasma (28) on the electrode (27) of the instrument (15). To accomplish this, the apparatus (14) comprises a control device (23) that, during an ignition test, limits—preferably in an instrument-specific manner—the current deliverable to the instrument (15) and/or limits the electrical power to be output to the instrument (15), and/or, in doing so, works with a reduced operating voltage. With this measure, a rapid, stable plasma development with minimal spark play is achieved with a large variety of connectable instruments (15a-15e).
