Abstract: A method and system for hair treatment comprising a laser module configured for generating non-ablative laser; a handpiece connected to the laser module configured to receive the non-ablative laser and deliver a fractional pattern of the non-ablative laser to a treatment site on a person's scalp. A controller for controlling parameters of the non-ablative laser to apply the hair and activating the laser module for a predetermined treatment time, at a predetermined pulse rate, and a predetermined pulse duration. Delivering, by the handpiece, the non-ablative laser to the treatment site on the person's scalp; and deactivating, by the controller, the laser module.

Abstract: The present invention provides methods for providing cartilage-containing tissue for grafting, comprising providing excised cartilage-containing tissue; and treating said excised cartilage-containing and cryogenically preserving the treated cartilage-containing tissue under appropriate cryogenic preservation conditions so as to yield cryogenically preserved cartilage-containing tissue having at least 10% viable chondrocytes throughout the cartilage portion of the cartilage-containing tissue after preservation, as tested in a live/dead ratio assay. Treatment may comprise providing one or a plurality of incisions in said cartilage portion to a predetermined depth therein and/or introducing a cryoprotectant agent at least into said cartilage portion.
