Disclosed herein are apparatuses, systems, kits, and methods for treating skin, such as skin tightening or for treating diseases, disorders, and conditions that would benefit from tissue area or volume reduction, skin restoration, skin tightening, skin lifting, and/or skin repositioning and/or for generally improving skin function or appearance (e.g., the removal of unwanted skin features or irregularities such as sebaceous glands, sweat glands, hair follicles, necrosis, and fibrosis). Such apparatuses, systems, kits, and methods comprise an apparatus having a handheld main body and a detachably attachable tip comprising one or more needles.

Methods and systems are disclosed for removing a tattoo from a subject's skin by application of a cold plasma that is delivered via a liquid-gas mixture. The plasma can be delivered in the form of gas bubbles, in which at least a portion of gas is in the form of a plasma.

A system comprising a handpiece and drive system configured to removably couple to a proximal end of a housing. A scalpet assembly is configured to removeably couple to the housing, and includes a scalpet array comprising at least one scalpet configured for rotation. The scalpet array is configured to harvest dermal plugs via fractional resection. A collection chamber is configured to collect the dermal plugs, and to house formation of an injectable filler by mincing the dermal plugs, and mixing the dermal plugs with a carrier. The injectable filler is configured for bulk fill. The collection chamber includes a loading port, and a cannular syringe is configured to mate with the loading port to receive the injectable filler, and to deliver the injectable filler for the bulk fill.

Systems and methods for creating a treatment plan for cosmetic procedures, for example, a hair transplantation procedure, are provided. The treatment plan allows user to provide input on a proposed hair element using a free-hand drawing in a two-dimensional plane, and for the proposed hair element to be generated and displayed on a three-dimensional model of a body surface. Various techniques and methods described in the application provide for improved planning of a natural looking hair.

Systems and methods for creating a treatment plan for cosmetic procedures, for example, a hair transplantation procedure, are provided. The treatment plan allows creating a natural looking hair whorl either automatically, with a user input, or by a combination of both. Various techniques and methods described in the application provide for improved planning of a natural looking hair.

Embodiments of a method for removing a tattoo through patterned trans-epidermal pigment release includes determining first treatment area of skin of a patient through a primary template including primary apertures, marking the first treatment area of skin of the patient along borders of the primary apertures to outline a grid of primary tegulae, and delivering a tattoo removal fluid to the marked first exposed skin in a first treatment session. The method further includes determining a secondary treatment area through a secondary template including secondary apertures, marking the secondary treatment area along borders of the secondary apertures to outline a grid of secondary tegulae, and delivering a tattoo removal fluid to the secondary tegulae in a second treatment session.

Embodiments of an apparatus include a needle cartridge configured to attach to and interface with an actuating device. The needle cartridge includes a housing, a needle group assembly, and a fluid port. The housing forms a cavity and includes a first aperture and a second aperture opposite the first aperture. The needle group assembly includes a needle and a needle holder. The needle group assembly is configured to move in a reciprocating motion relative to the housing along an axis from the first aperture to the second aperture. During the reciprocating motion, the needle fully retracts into the cavity through the first aperture. The fluid port is integrated with the housing and includes a hollow projection forming a conduit and extending away from the housing. The fluid port includes a third aperture, wherein the fluid port is configured to interface with a fluid delivery system.

Embodiments of an actuating device for actuating a needle cartridge and puncturing an epidermis with controlled depth. The actuating device includes a motor housed in a motor housing, an actuating rod driven by the motor and configured to actuate in a reciprocating motion, and an adjustment mechanism. The actuating rod is housed in a rod housing, the rod housing forming a device aperture configured to receive a needle cartridge and to attach to the needle cartridge. The adjustment mechanism interfaces with the rod housing and is configured to adjust a position of the rod housing relative to the motor housing while not rotating the rod housing relative to the motor housing.

Disclosed herein are apparatuses, systems, kits, and methods for treating skin, such as skin tightening or for treating diseases, disorders, and conditions that would benefit from tissue area or volume reduction, skin restoration, skin tightening, skin lifting, and/or skin repositioning and/or for generally improving skin function or appearance (e.g., the removal of unwanted skin features or irregularities such as sebaceous glands, sweat glands, hair follicles, necrosis, and fibrosis). Such apparatuses, systems, kits, and methods comprise an apparatus having a handheld main body and a detachably attachable tip comprising one or more needles.

In combined methods for treating a patient using time-varying magnetic field, treatment methods combine various approaches for aesthetic treatment. A magnetic field generating device is placed proximate to a body region of the patient. The magnetic field generating device generates a time-varying magnetic field with a magnetic flux density in a range of 0.5 to 7 Tesla. The time-varying magnetic field is applied to the body region of the patient in order to cause a contraction of a muscle within the body region. A second therapy may be used by applying one or more of optical waves, radio frequency waves, mechanical waves, negative or positive pressure or heat to the body region of the patient.
