20100099772METHODS, COMPOSITIONS, AND KITS FOR TREATING PAIN AND PRURITIS - The invention features a method for inhibiting one or more voltage-gated ion channels in a cell by contacting the cell with (i) a first compound that activates a channel-forming receptor that is present on nociceptors and/or pruriceptors; and (ii) a second compound that inhibits one or more voltage-gated ion channels when applied to the internal face of the channels but does not substantially inhibit said channels when applied to the external face of the channels, wherein the second compound is capable of entering nociceptors or pruriceptors through the channel-forming receptor when the receptor is activated. The invention also features a quarternary amine derivative or other permanently or transiently charged derivative of a compound that inhibits one or more voltage-gated ion channels when applied to the internal face of the channels but does not substantially inhibit said channels when applied to the external face of the channels.04-22-2010

20110040358Portable Semiconductor Diode Laser for Medical Treatment - Semiconductor lasers, in which the laser diode output is used directly for medical treatment, can be compact, lightweight and efficient. Lasers operating in the relatively “eye-safe” window of about 1350-1600 nm can be used to treat wounds and diseases of the skin and other organs, for example to cut, ablate or coagulate bodily tissues and fluids. Because the wavelength is eye-safe, the treatment can be through-space, and does not require the use of a fiber optic containment system. The device need not directly contact tissue. Such devices can be battery operated, are portable and self-contained, and thus are suitable for uses that are not confined to medical facilities, including use in emergency situations and in military operations.02-17-2011
20110122905SEMICONDUCTOR LASER ASSEMBLY AND PACKAGING SYSTEM - A system for self-aligning assembly and packaging of semiconductor lasers allows reduction of time, cost and testing expenses for high power density systems. A laser package mounting system, such as a modified TO-can (transistor outline can), has modifications that increase heat transfer from the active laser to a heat exchanger or other heat sink. A prefabricated heat exchanger assembly mounts both a laser package and one or more lenses. Direct mounting of a fan assembly to the package further minimizes assembly steps. Components may be physically and optically aligned during assembly by clocking and other indexing means, so that the entire system is self-aligned and focused by the assembly process without requiring post-assembly adjustment. This system can lower costs and thereby enable the use of high powered semiconductor lasers in low cost, high volume production, such as consumer items.05-26-2011

20080287741ARTICULATING TORQUEABLE HOLLOW DEVICE - An articulating mechanism for use in a medical device, such as an endoscope or a catheter, includes a series of stacked links disposed adjacent to one another and movable with respect to each other. Each link includes a front face tapered to a pair of pivot points and a rear face defining a wedge shaped recess for receiving the pivot points of the adjacent link. Pull-wires provide tension and hold the staked links together while also allowing for controlled bending of the distal portion by movement of one or more of the pull-wires.11-20-2008

20120240378LOADER FOR IMPLANT DELIVERY TOOLS AND METHODS OF USING THE SAME - An apparatus includes a base portion, a first side portion, and a second side portion. The base portion, the first side portion, and the second side portion collectively define a cavity. The cavity is configured to receive a filament. The cavity is also configured to receive at least a portion of a delivery tool such that a coupling portion of the delivery tool is aligned with the filament. In some embodiments, the cavity includes a first end portion and a second end portion. The cavity is configured to receive the filament such that it extends from the first end portion of the cavity to the second end portion of the cavity. The cavity is configured to receive the at least a portion of a delivery tool such that the coupling portion of the delivery tool is disposed between the first end portion of the cavity and the second end portion of the cavity.09-27-2012
