摘要： A method and apparatus for mechanically disrupting a layer of skin having a known thickness without substantially disrupting underlying dermis layers below the layer of skin in question so as to facilitate the delivery of compounds across the disrupted layer. The apparatus includes a cutter having a plurality of microprotrusions having a height chosen with respect to the layer of skin that is to be disrupted and a stop for preventing the apparatus from penetrating the skin beyond a predetermined distance. In the preferred embodiment of the present invention, the microprotrusions include blades that generate cuts in the layer of skin. The cuts are generated by moving the apparatus parallel to the surface of the skin either at the time of application, during the normal movements of the individual wearing the apparatus, or both. In the preferred embodiment of the present invention, the appropriate length of blade is determined for each individual and delivery site on that individual.

摘要： The present invention relates to methods and devices used for the formation of microconduits in a tissue. The term “microconduit” refers to a small opening, channel, or hole into, or through, a tissue, that allows transfer of materials by liquid flow, and by electrophoresis, the microconduit being formed upon impact of a plurality of accelerated microparticles with the surface of the tissue. A method is described for forming at least one microconduit in tissue including the steps of: accelerating a plurality of microparticles to a velocity that causes the microparticles to penetrate a region of tissue surface upon impingement of the microparticles on the tissue surface; and directing the microparticle towards the region of tissue surface, thereby causing the microparticles to penetrate the tissue and form a microconduit in the tissue. According to an embodiment, microparticles are accelerated by being hit with a moving, solid surface. In another embodiment, microparticles are accelerated by a flowing gas or liquid. Also described are methods and devices for using microconduits to deliver therapeutic molecules and ions into tissue, or for extraction of chemical analytes out of tissue. Also described is a method of nail piercing to accommodate jewelry.

摘要： The invention features systems and tools for controlling the optical penetration depth of laser energy, e.g., when delivering laser energy to target tissue in a patient. The systems and tools control the optical penetration depth (OPD) by controlling the incident angle at which the laser energy is delivered to the target area of the patient. Embodiments of the invention include an optical coupler that permit a user to vary the incident angle and thereby selectably control the OPD of incident laser energy. Fabricating the optical coupler to have a refractive index greater than that of the target tissue can enhance the range of selectable OPDs. The laser energy, which is delivered to the desired depth, can cause alteration of the target tissue by, e.g., heating, ablation, and/or photochemical reaction.

摘要： Method for treating a proliferative skin disorder, such as psoriasis, in a human patient having affected and non-affected areas of skin. The method comprises the steps of: (1) topically applying a sunscreen providing photo-protection to the affected and non-affected areas of skin; (2) waiting for a time period sufficient for the skin of the affected areas to be substantially sloughed off; and, (3) exposing the affected and non-affected areas of skin of the patient to a selected level of optical radiation. The level of radiation is chosen to be sufficient to treat the affected areas of skin and insufficient to cause significant damage to the non-affected areas of skin. The method enhances effectiveness and safety of treatment by providing preferential photo-protection to the non-affected skin areas, and may be used for phototherapy, photochemotherapy, or photodynamic therapy.

摘要： The invention features a probe for selectively delivering laser radiation to a first tissue having a first index of refraction relative to a second tissue having a second index of refraction less than the first index. The probe includes a laser transmitting medium having an optical axis and a tissue-contacting surface. In some embodiments, the optical axis contacts the tissue-contacting surface at an angle that is less than the critical angle for an interface between the tissue-contacting surface and the first tissue and greater than or equal to the critical angle for an interface between the tissue-contacting surface and the second tissue, wherein during operation the probe directs the laser radiation along the optical axis to the tissue-contacting surface. In other embodiments, the optical axis forms an angle with the tissue-contacting surface, and during operation the probe directs the laser radiation along the optical axis to the tissue-contacting surface, transmits a first amount of laser energy through the tissue-contacting surface when contacting the first tissue, and transmits a second amount of laser energy through the tissue-contacting surface when contacting the second tissue, wherein the angle is selected such that the first amount of laser energy is at least twice the second amount of laser energy. The invention also features related methods for selectively delivering laser radiation to tissue based on refractive index.

摘要： A confocal microscope for generating an image of a sample includes a first scanning element for scanning a light beam along a first axis, and a second scanning element for scanning the light beam at a predetermined amplitude along a second axis perpendicular to the first axis. A third scanning element scans the light beam at a predetermined amplitude along a third axis perpendicular to an imaging plane defined by the first and second axes. The second and third scanning element are synchronized to scan at the same frequency. The second and third predetermined amplitudes are percentages of their maximum amplitudes. A selector determines the second and third predetermined amplitudes such that the sum of the percentages is equal to one-hundred percent.
