Abstract: Diffraction grating based fiber optic interferometric systems for use in optical coherence tomography, wherein sample and reference light beams are formed by a first beam splitter and the sample light beam received from a sample and a reference light beam are combined on a second beam splitter. In one embodiment, the first beam splitter is an approximately 50/50 beam splitter, and the second beam splitter is a non 50/50 beam splitter. More than half of the energy of the sample light beam is directed into the combined beam and less than half of the energy of the reference light beam are directed into the combined beam by the second beam splitter. In another embodiment, the first beam splitter is a non 50/50 beam splitter and the second beam splitter is an approximately 50/50 beam splitter. An optical circulator is provided to enable the sample light beam to bypass the first beam splitter after interaction with a sample.

Abstract: Various embodiments of the present invention comprise a signal generator for sending an electrical signal from an expandable, flexible layer of material, the signal generator comprising an upper layer of flexible, resilient material and a lower layer of flexible, resilient material which between them define a cavity for enclosing an expandable material such as a cellular foam or gas, whereupon localized distortion of one of the layers of flexible material, effects a signal generation within the structure, which is transmissible through a proper circuit to an outside electrical device. A circuit may be arranged adjacent a plurality of said keys which senses when several of said keys are depressed in a skewed or sideways manner, so as to effect movement of a cursor or pointer on a monitor in communication with a processing unit and said keyboard.

Abstract: A medical device and system capable of providing on-demand delivery of biologically active material to a body lumen patient, and a method of making such medical device. A first coating layer comprising a biologically active material and optionally a polymeric material is disposed on the surface of the medical device. A second coating layer comprising magnetic particles and a polymeric material is disposed on the first coating layer. The second coating layer, which is substantially free of a biologically active material, protects the biologically active material prior to delivery. The system includes the medical device and a source of energy, such as an electromagnetic or mechanical vibrational energy. When the patient is exposed to the energy source, the magnetic particles move out of the second coating layer and create channels therein through which the biologically active material can be released.

Abstract: A medical system includes a catheter having an elongated tubular member and an inner core slideably received within the elongated member. The inner core includes an imager on a distal end and is coupled with a control system and an imaging system. The inner core is configured to scan the interior of a lumen by radially rotating around a center axis and axially translating along the center axis while within the elongated member. The medical system is configured to dynamically image a body lumen at a high speed in order to allow for optical imaging in a safe manner without long durations of blood sequestration and displacement. The medical system is configured to obtain three dimensional images of the body lumen with as little as one dimensional scanning of the lumen. Images of the lumen can be stored and viewed at a desired rate after scanning.
