摘要:
The present invention includes an apparatus and methods for differentially perfusing a patient undergoing cardiopulmonary bypass. A cardiopulmonary bypass machine is configured to provide hypothermic oxygenated blood and normothermic oxygenated blood to an aortic balloon catheter. The catheter has arch perfusion ports and corporeal perfusion ports and is introduced into a patient's aorta and navigated transluminally until the occlusion balloon is located in the descending aorta. The occlusion balloon is inflated and hypothermic oxygenated blood is perfused to the arch vessels while normothermic oxygenated blood is perfused to the corporeal circulation. This procedure offers the benefit of cerebral protection from embolic events during cardiopulmonary bypass surgery.

The present invention relates to catheters for selectively cooling or warming tissue within a patient's vasculature. The present invention utilizes novel heat exchanging devices, which reside inside the catheter body for selectively altering the temperature of fluid that flows through the catheter shaft. In addition, the present invention utilizes novel pumping devices, which reside within a patient's vasculature for withdrawing oxygenated blood into the catheter body where heat exchange occurs across a heat transfer interface for selective cooling or warming of the blood occurs. The present invention can be used in a multiplicity of medical disciplines where it is advantageous to selectively alter the temperature of tissue, including beating heart applications, as well as stopped heart medical interventions.
摘要:
The present invention provides methods, systems and devices for performing cardipulmonary bypass (CPB), cardioplegic arrest, suction of fluid from the aorta to remove embolic or other fluid from the general circulation and the selective segmentation of the arterial system to perform differential perfusion eliminating hypoperfusion. An aortic catheter having an arch lumen which extends at least in part along the length of the catheter shaft has a proximal opening coupled to a CPB machine and a distal arch opening. A corporeal lumen extends at least in part along the length of the catheter shaft and has a proximal opening coupled to a CPB machine and a distal corporeal opening. A suction lumen extends at least in part along the length of the catheter shaft and has a proximal suction opening coupled to a suction source and a distal suction opening residing in the aortic lumen of a patient.

Handles, apparatus devices, and methods for clamping and using an extra handle onto fishing rods that provides enhanced leverage while holding the existing elongated handle on the rod between clamps on the extra handle, as well as being used for carrying the rod before and after it is being used. The extra handle has bent member between two clamp ends with an inner generally wide flat smooth face, and lower and upper smooth perimeter edge surfaces, that provide a comfortable surface against the back of the hand of the fisherman and helps provide leverage to the fisherman while fishing with the rod and carrying the rod before and after use.

A traction unit capable of traversing and turning on surfaces that include compound curves like the surface of a sphere or are inverted like a ceiling. The traction unit includes a plurality of trucks operable to propel the unit across a surface and a plurality of adherence members operable to releasably secure the unit to the surface. In operation, the adherence members cyclically attach to and release from the surface as the trucks propel the unit across the surface. Within each cycle, after the unit has traveled a predetermined distance relative to an attached member, the member releases the surface and reattaches to the surface at a different point.

摘要:
Systems and methods may apply global contrast correction to a plurality of thermal images. For example, a vehicle may capture a plurality of aerial thermal images for use in generating a composite image. Each individual thermal image may be individually contrasted based on the temperature range of pixels in that image, so the contrast range of the thermal images may vary. The plurality of thermal images may be analyzed to determine a global contrast range. Extreme temperatures may be excluded from the global contrast range. Based on the global contrast range, a contrast level of each of the plurality of thermal images may be adjusted. For example, the individual temperature range of each thermal image may be scaled to a global temperature range. A composite image having consistent contrasting may be generated from the plurality of thermal images.
摘要:
Aerial thermal images of a ground surface may be captured using a thermal image sensor. The images may be contrasted, georeferenced, orthorectified, and/or stitched together to form a complete thermal image. The complete thermal image may include a plurality of pixels with display values corresponding to temperatures of the ground. Local temperature sensors may measure the temperature at locations on the ground. Based on display values for pixels corresponding to the locations on the ground and the temperature measurements, a curve mapping display values to temperature measurements may be calculated. Temperatures may be calculated for pixels for which the temperature was not previously known. Users may select a temperature range of interest, and pixels with temperature values within the temperature range of interest may be distinctively marked. The pixels may be marked with different colors based on where their temperature value falls within the temperature range of interest.

A priority restore agent in a data storage system generates a priority restore data set for a client computer system or device by identifying a set of active data sets and/or a set of key data sets within client system data generated by the client computer system. The priority restore agent looks at or processes file system attributes for the client system data and compares these attributes with predefined restore parameters. The restore parameters may indicate that any file that has been accessed, modified, or created within a particular period of time be included in the priority restore data set. The key data sets may be identified in a set of automated restore rules. A data protection application within the data storage system can restore data in the priority restore data set onto the client computer system after a disaster or system crash.
