Abstract: Certain embodiments include an endoscope and methods for imaging using the endoscope. The endoscope may include an imaging channel and a tip positioned at one end of the imaging channel, the tip adapted to collect light from a field of view that extends 360° around at least a portion of the endoscope and to transmit the light to the imaging channel. Certain embodiments may also utilize various sensors, controllers and processing mechanisms to record and process images into a representation, move the endoscope in and out of the endometrial cavity, and to biopsy a portion of the endometrium.

Abstract: Methods for identifying and extracting heart depolarization and repolarization in a paced heart. Certain methods also include identifying and analyzing particular features of at least one pacing spike and QRS waveform for heart beat characterization. These features may include signal changing speed and signal time interval (distance) of pacing spikes and QRS depolarization when pacing excitation is initialized.

Abstract: Embodiments include methods and apparatus for determining whether a neurological event has occurred in a subject. An apparatus includes at least one sensor adapted to sense electroencephalogram signals from the subject. The apparatus also includes an electroencephalogram acquisition module adapted to receive the electroencephalogram signals from at least one sensor, and a processing and analysis module adapted to receive signals from the electroencephalogram acquisition module and determine changes in neurological function using entropy analysis.

Abstract: One embodiment enables detection of MI/I and emerging infarction in an implantable system. A plurality of devices may be used to gather and interpret data from within the heart, from the heart surface, and/or from the thoracic cavity. The apparatus may further alert the patient and/or communicate the condition to an external device or medical caregiver. Additionally, the implanted apparatus may initiate therapy of MI/I and emerging infarction.

Abstract: An implantable apparatus may include a plug member having a lumen and a valve adapted to open and close the lumen in response to a signal. The apparatus may also include at least one sensor and a controller adapted to control the valve. The controller may be programmable to open the valve to permit the flow of urine under at least one mode of operation selected from a predetermined time interval operation, a sensor operation, and a manual actuation operation.

Abstract: A device and method for performing particle separation. Separation and purification of biological macromolecules are important steps in basic molecular biology research and biotechnology product development. Throughout the years researchers have worked on developing different and better techniques. The present invention is directed to a new technique for separation of charged particles by applying a magnetic field parallel to the axis of rotation during centrifugation. Magnetocentrifugation performed according to the present invention thus enhances the separation of charged particles under centrifugation by adding a magnetically induced force, namely a Lorentz force, in addition to centrifugal, buoyant, and frictional forces. The technique of magnetocentrifugation may be utilized for separating particles with similar densities but different charges, and may be used for free as well as immobilized charged macromolecules such as proteins and DNA.

Abstract: An automated method and apparatus determines characteristics of nerve fibers. The apparatus includes an imaging unit that creates a digital image data representative of an image of a cross-section of a nerve fiber to be tested; a control unit, including image processing capability, is coupled to the imaging unit and analyzes the digital image data created by the imaging unit to identify particular characteristics of the nerve fibers including axon area, the myelin sheath area, the fiber area, the myelin sheath thickness, the fiber perimeter and the fiber eccentricity.
