    摘要： An illuminator including a differential optical radiator and a laser fiber disposed within the differential optical radiator. The differential optical radiator includes a first region that has a first level of reflectivity and a first level of transmissivity and a second region that has a second, higher level of reflectivity and a second, lower level of transmissivity. The first and second regions are positioned such and their reflectivities and transmissivities are chosen such that the radiator produces a substantially uniform pattern of illumination from the first and second regions. In another embodiment, the illuminator includes an expandable radiator and a laser fiber disposed within the expandable radiator. The reflectivity of the expandable radiator is such that the illumination at the outer surface of the expandable radiator is substantially uniform.

    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： 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： A method for conducting laser energy to a site includes steps of bringing the proximal end of a flexible tube near the site, filling at least a proximal portion of the tube with a liquid by introducing the liquid into the tube, allowing a portion of the liquid to flow out from the proximal end of the tube toward the site, and directing laser energy from a laser energy source into the distal end of the tube, whereby a portion of the laser energy emerges from the proximal end of the tube at the site. Also, such a method in which the liquid is a radiographic contrast medium. Also, such a method for removing an obstruction from a blood vessel in an animal. Also, apparatus for delivering laser energy to a site includes a flexible tube, a liquid, the tube having an opening in a first end through which the liquid can pass, means for providing a flow of the liquid into the tube, and a source of laser energy operationally associated with a second end of the tube, wherein the tube and the liquid are adapted to cooperate, when the tube contains the liquid, to conduct laser energy from the source and to emit a portion of the laser energy from the first end of the liquid-containing tube.
