Abstract: An LED display with a reduced thickness is described. In one embodiment, the LED display includes a second support plate between a front support plate and a back support plate. The second support plate enables the front support plate to be thinner than if the second support plate was not included. The second support plate increases the distance between an LED chip and a light exit surface thereby allowing the front support plate thickness to be reduced by about the thickness of the second support plate. In one embodiment, the second support plate allows the thickness of an LED display to be thinner. The second support plate adds structural integrity to a back support plate. Therefore, the back support plate can be thinner, and thickness of the LED display can be reduced.

Abstract: Embodiments of the invention are directed to a medical device and methods for immobilizing and retrieving material from a patient's body. The device may include a sheath having a lumen, a distal end, and a proximal end. An elongate member is provided including an expansible member connected to a distal portion of the elongate member. The elongate member and expansible member are movable relative to the sheath to achieve a first state of the expansible member when the expansible member is within the lumen of the sheath and an expanded state when the expansible member extends from the distal end of the sheath. The expansible member comprises a material that expands to the expanded state due to the presence of fluid.

Abstract: According to an aspect of the present invention, urological medical devices are provided, which contain one or more urologically beneficial agents selected from alpha-adrenergic blockers, calcium channel blockers, and combinations thereof, among others. The urological devices are adapted for implantation or insertion into a subject's urinary tract, whereupon at least a portion of the urologically beneficial agent is released. Such agents are urologically beneficial, for example, in that they may relieve pain and/or discomfort associated with the medical device and/or act as stone expulsion agents (i.e., they facilitate stone passage), among other benefits. According to an aspect of the present invention, a method of treating kidney stones is provided which comprises: (a) diagnosing the presence of kidney stones within a subject and (b) implanting or inserting a urological medical device into the subject which contains at least one urologically beneficial agent. The medical device is adapted to release the at least one urologically beneficial agent in vivo in an amount effective to promote kidney stone expulsion.
