Abstract:
An intracellular delivery system and method are provided. The intracellular delivery system comprises a laser-activated surface and cells positioned at a distance from the laser-activated surface. A laser provided a laser pulse that is used to porate membranes of the cells to deliver or extract cargo from the cells into a liquid surrounding the cells. The method of intracellular delivery comprises positioning a laser-activated surface at a distance from cells and applying a laser pulse from the laser to the surface to porate membranes of the cells to deliver or extract cargo from the cells into a liquid surrounding the cells.
Abstract:
Disclosed is a system and method for treatment of skin disorders. More particularly, the disclosed invention is directed toward the use of multiple light sources for treating skin with or without the use of a topical compositions or photomodulation enhancing agents. Dual light emitting diodes may, for example, be used at relatively low power (less than about 10 J/cm2) to photomodulate skin or living tissue to reduce wrinkles, fine lines, acne, acne bacteria, and other skin disorders.
Abstract:
The present invention provides methods of treating baldness in a subject and generating new hair follicles, comprising epidermal disruption and administration of a compound that promotes a differentiation of an uncommitted epidermal cell into a hair follicle cell. The present invention also provides methods for hair removal and inducing hair pigmentation.
Abstract:
A method of enhancing the permeability of a biological membrane, including the skin or mucosa of an animal or the outer layer of a plant to a permeant is described utilizing microporation of selected depth and optionally one or more of sonic, electromagnetic, mechanical and thermal energy and a chemical enhancer. Microporation is accomplished to form a micropore of selected depth in the biological membrane and the porated site is contacted with the permeant. Additional permeation enhancement measures may be applied to the site to enhance both the flux rate of the permeant into the organism through the micropores as well as into targeted tissues within the organism.
Abstract:
Apparatus for delivering toxin and toxin fragments to a patient's nasal cavity provide for both release of the toxin and delivery of energy which selectively porates target cells to enhance uptake of the toxin. The use of energy-mediated delivery is particularly advantageous with light chain fragment toxins which lack cell binding capacity.

Abstract:
A system for producing preferential damage to hair exiting mammalian skin. A agent having an average diameter for enabling the agent to penetrate the hair duct is selected. The agent is designed to attach to, or become physically incorporated into, the hair shaft, the hair follicle, the hair bulb or the hair duct. The agent has an electromagnetic radiation absorption characteristic which enables the agent to absorb a first wavelength of electromagnetic radiation from a skin-penetrating electromagnetic radiation source, such as a laser. The agent is applied to the skin so that the agent penetrates the skin and attaches to or becomes physically incorporated into the hair shaft, the hair follicle, the hair bulb or the hair duct. The agent is exposed to the first wavelength of electromagnetic radiation and absorbs the first wavelength of electromagnetic radiation.
Abstract:
A device and methods for increasing the permeability of the skin's surface to fluid and/or drug delivery is described. The device comprises an abrasive media to remove the outer layer of the stratum corneum, while at the same time applying an electric current that stimulates the skin under the stratum corneum, and delivers fluids from a supply reservoir. The device may also have a vacuum function which evacuates fluid and skin debris from the surface of the skin and delivers the evacuated fluid and skin debris to a waste (or collection) container.
Abstract:
An applicator for use with an ultrasound transducer assembly is disclosed. In an embodiment, an applicator includes a nozzle body having an interior and an exterior surface; a nozzle liner having an interior and an exterior surface and being engageable with the nozzle body such that a plurality of channels are defined at least in part by the exterior surface of the nozzle liner and the interior surface of the nozzle body, each of the plurality of channels having an inlet and an outlet; a passageway defined by a space between the nozzle body and the nozzle liner, in fluid communication with the inlets of each of the plurality of channels; and an opening sized and shaped for introducing fluid to the passageway to provide fluid flow from the outlet of each of the plurality of channels essentially simultaneously. Kits and methods are also disclosed.
Abstract:
Photocosmetic device for use in medical or non-medical environments (e.g., a home, barbershop, or spa), which can be used for a variety of tissue treatments. Radiation is delivered to the tissue via optical systems designed to pattern the radiation and project the radiation to a particular depth. The device has a variety of cooling systems including phase change cooling solids and liquids to cool treated skin and the radiation sources. Contact sensors and motion sensor may be used to enhance treatment. The device may be modular to facilitate manufacture and replacement of parts.
