Abstract:
A system for controlling a patient temperature uses a central venous line catheter (100) having axially spaced distal and proximal heat exchange balloons (102/104). The central venous line catheter (100) is provided with one or more lumens (128) for providing access to the central blood supply of the patient, and with additional lumens (106/108) for communicating heat exchange fluid to the balloons (102/104). Heat exchange fluid temperature is controlled through a feed back loop in which patient temperature is sensed and used to control a temperature control unit (50) comprising a heating device and/or a cooling device in heat exchange relationship with the heat exchange fluid. A tubing set (120/122) transports the heat exchange fluid between the central venous line (100) and the temperature control unit (50), with a pump serving to circulate the fluid in a closed fluid circuit in the system.

Abstract:
A system and method for fixed or snap-on emergency exit LED lighting. The emergency exit lighting fixture comprises a structure for housing at least one LEO light, an LED driver electronically coupled to the LED lights), a.continuous power source, a backup power source, and a test switch. The fixture, in various configurations, may be mounted to an existing T-grid. The fixture may be tested remotely.
Abstract:
Embodiments of the invention are directed to methods of treating, inhibiting or attenuating a microbial infection in an individual who has or is at risk for developing such an infection, comprising the step of administering an effective amount of a StIR polypeptide or peptide or fragment or derivative or analog thereof to the individual.
Abstract:
A method for treating cardiac arrest includes defibrillating (38) the patient, and/or ventilating (42) the patient, administering a cardiac arrest drug such as epinephrine to resuscitate the patient, then cooling the patient using one or more cooling catheters (18) positioned in the central venous system of the patient.
Abstract:
A malfunction management unit (MMU) includes advanced diagnostic and set-up capabilities accessed through a display-based user interface. In general, the MMU is capable of displaying (1) monitor status information, wherein the monitor status information includes information relating to the status of at least a portion of the input signals; and (2) diagnostic information, wherein the diagnostic information includes an indication of fault type, an indication of faulty signals, and troubleshooting information associated with said fault type and relevant faulty signals. The diagnostic information includes a textual interpretation of the results of a field check analysis.
Abstract:
The present technique provides for the analysis of a data series to identify sequences of interest within the series. The analysis may be used to iteratively update a grammar used to analyze the data series or updated versions of the data series. Furthermore, the technique provides for the calculation of a minimum description length heuristic, such as a symbol compression ratio, for each sub-sequence of the analyzed data sequence. The technique may then compare a selected heuristic value against one or more reference conditions to determine if additional iteration is to be performed. The grammar and the data sequence may be updated between iterations to include a symbol representing a string corresponding to the selected heuristic value based upon a non-termination result of the comparison. Alternatively, the string corresponding to the selected heuristic value may be identified as a sequence of interest based upon a termination result of the comparison.
Abstract:
An accommodating intraocular lens (200, 300, 400) has an anterior portion (102) including an anterior viewing element (106) and an anterior biasing element (108) connected to the anterior viewing element (106). A posterior portion (104) has a posterior viewing element (118) and a posterior biasing element (120) connected to the posterior viewing element (118). The anterior and posterior biasing elements (108, 120) are connected at first and second apices (112, 116). First and second distending members (134, 136) are connected to the posterior portion (104). The first and second distending members (134, 136) extend to locations significantly anterior of an anterior side of the posterior viewing element (118).
Abstract:
A system and method linking one or more disparate datasets (306) with one or more spatial layers to create linked datasets (Figure 3). One or more data attributes common to the dataset and the spatial layer (302) are identified, and the linkage is defined between the dataset and the spatial layer. The spatial layer and the linked data set (312) then may be queried using a singe input query. Features from the spatial layer and features from the linked dataset that match the query are generated for display.
Abstract:
A catheter is adapted to exchange heat with a body fluid, such as blood, flowing in a body conduit, such as a blood vessel. The catheter can be positioned to produce hypothermia in a selective area of the body without cooling the entire body system. It is of particular advantage in brain surgeries where stoke, trauma or cryogenic tumors can best be addressed under hypothermic conditions. Heat pipe technology can be used to form a heat pipe heat exchange catheter (10). The heat pipe heat exchange catheter includes metallic bellows (214) which allow for flexibility. The temperature control source (212) can be portable to enable the heat pipe heat exchange catheter to be used in the ambulatory environment.
