Devices and methods for performing subcutaneous surgery in a minimally invasive manner are provided. The methods include application of reduced air pressure in a recessed area of a handpiece placed over a section of skin and drawing the section of skin and subcutaneous tissue into the recessed area. In a subsequent step a tool is inserted through a tool conduit in the handpiece and through the skin into the subcutaneous tissue, enabling the performance of the desired surgery. Common surgical procedures include dissection and ablation . The devices and methods can be directed at the treatment of skin conditions like atrophic scars, wrinkles, or other cosmetic issues, at treatments like or promoting wound healing or preventing hyperhidrosis, or can be used for creating space for various implants.

The present invention is directed to improved systems, devices, and methods for delivery of a cryogen to the skin of a patient for skin treatment. A cryospray device configured to deliver a cryogen to a patient's skin can include an applicator, a supply channel, and a nozzle assembly. The applicator can include a head portion, and the supply channel can extend through at least a portion of the head portion. The nozzle assembly can be coupled to the head portion and can be fluidly coupled to the supply channel. The nozzle assembly can include a linear array of orifices that are configured to direct a planar spray of the cryogen to cool an area of a skin tissue of the patient in a linear cooling treatment.

Systems, devices, and methods for treating a skin of a patient with therapeutic laser light via imaging a first skin area of the patient to obtain at least a first image, processing the at least a first image of the first skin area with at least one processor to identify within the first skin area at least one or more target skin areas and a non-target skin area, generating a treatment map of the first skin area based on the identified one or more target skin areas and the non-target skin area, and treating at least a portion of the one or more target skin areas with therapeutic laser light based on the generated treatment map.

Embodiments include a system comprising a cannula assembly configured for rotational fractional resection (RFR). The cannula assembly includes at least one cannula configured for rotational operation and enclosed in a depth guide configured to control an insertion depth of the at least one cannula. The depth guide includes a vacuum chamber configured to maintain vacuum to evacuate resected tissue generated by the RFR.

Lysing surgical instruments and related systems and methods. In some embodiments, the instrument may comprise a lysing tip comprising at least one bead. The at least one bead may comprise an at least substantially electrically non-conductive surface and at least one lysing member defining at least one lysing segment extending within a recess defined, at least in part, by the at least one bead. The at least one bead may also protrude both distally and proximally relative to the at least one lysing member.

A method of treatment of skin tissue with two laser devices of unequal wavelengths comprising the steps of: (1) activating the two laser devices simultaneously to produce two laser beams of unequal wavelength; (2) directing the two laser beams into a handpiece having a distal tip to direct the laser beams onto the skin tissue; (3) directing the two laser beams within the handpiece to an adjustable beam deflector; and, (4) the adjustable beam deflector directing the two laser beams onto the skin tissue to produce a pattern of laser spots simultaneously but separated from one another.

Embodiments include a system comprising a carrier and a cannula assembly. The carrier includes a proximal end and a distal end, and the proximal end is configured to removeably couple to a remote console. The cannula assembly, which is configured to removeably couple to the distal end of the carrier, is configured for rotational fractional resection (RFR) and includes at least one cannula rotatably coupled to the carrier and enclosed in a depth guide configured to control an insertion depth of the at least one cannula. The depth guide includes a vacuum chamber configured to form vacuum to evacuate resected tissue generated by the RFR.

A treatment apparatus for treating a skin lesion on skin of a patient, the apparatus comprising a source of electromagnetic radiation (16), a guide (6, 20) to guide the electromagnetic radiation to the skin lesion (25) and a control apparatus (1), the control apparatus (1) being arranged so as to cause the source (16) and the guide (6, 20) to: provide an initial burst of electromagnetic radiation to the skin lesion (25) to heat it to a first temperature selected by the control apparatus (1); cease providing electromagnetic radiation to the skin lesion (25) for a period; and provide a further burst of electromagnetic radiation to the skin lesion (25) so as to maintain the temperature of the skin lesion within a temperature range selected by the control apparatus (1). The apparatus may comprise a temperature sensor (24) which detects the temperature of the patient’s skin, typically the skin lesion.

A dual chambered syringe includes: an inner barrel defining a first inner chamber, the inner barrel having an apertured stopper at its distal end, the inner barrel being open at its proximal end; a shaft adapted to fit within the inner barrel, the shaft having a distal end which is engageable with the aperture of the stopper; a device for controlling engaging and disengaging of the distal end of the shaft with the aperture of the stopper; an outer barrel concentric with the inner barrel defining a second inner chamber, the outer barrel having a distal end for receiving and dispensing fluids and a proximal end into which the distal end of the inner barrel is insertable into the second inner chamber; the apertured stopper engages the second inner chamber of the outer barrel and selectively prevents or permits the passage of fluids between the outer barrel second chamber and the inner barrel first chamber; the inner barrel having an engageable surface on its outside surface; and, the outer barrel having operatively associated therewith an engaging device for selective engagement and disengagement with the engageable surface on the inner barrel.

Apparatus and methods for delivering coolant to an energy delivery device used to treat tissue with electromagnetic energy. A cooling system includes a pump that is configured to pump a coolant to the energy delivery device.
