Abstract: An apparatus is provided with instructions adapted to present aggregated or averaged data associated with potentially hazardous material management of a number of reference entities.

Abstract: The invention provides a medical device having a catheter with two lumens and a cooling system. The first lumen has a proximal end and communicates with a port at the distal end. The second lumen has a proximal end and communicates with a side port. The proximal ends of the lumens are connected to the cooling system. The cerebral spinal fluid can be drained from the side port of the first lumen. Methods for cooling the brain to prevent neurologic damage during head trauma or inadequate perfusion are also disclosed.

Abstract: The invention provides a medical device having two elongate catheters, a pump, and a refrigeration system. Each catheter has a proximal end, a distal end, a lumen therebetween and communicating with a distal port. The proximal ends of the catheters are connected to the pump and the refrigeration system. The distal ends are adapted for insertion into the subarachnoid space. The cerebral spinal fluid is aspirated from the first catheter to the pump, cooled to below body temperature, and returned to the second catheter. The flow rate of the cerebral spinal fluid is adjusted according the CSF pressure and temperature. Also described are methods of using the devices in treating patients suffering from neurologic complications that arise as a result of inadequate cerebral perfusion, such as cardiac arrest, cardiac failure, low cardiac output states, stroke, head injury, cerebral aneurysm surgery, open and closed cardiac surgery and aortic surgery.

Abstract: An order filling system utilizes a server computer, a controlling computer and location verification devices to direct an orderfiller to order items stored in an inventory storage area. The server computer transmits order information to the controlling computer via wireless radio frequency communications. The controlling computer communicates with location verification devices via short range wireless communications. The controlling computer provides the orderfiller with directions and pick quantities for each inventory item in an order. The location verification devices and location clips are mounted throughout the inventory area and on the inventory carriers. The location verification devices may have a low power mode which conserves electrical power while the location verification device is not being used.

Abstract: Methods for using blood pumps to treat heart failure are disclosed. The pump is mounted on an interior of a stent, does not occupy the entire lumen, and the stent is releasably mounted on a distal end of a catheter. The distal end of the catheter is inserted into a peripheral artery and advanced to position the stent at a region of interest within the descending aorta, the ascending aorta, or the left ventricle. The stent and the pump are released from the catheter, and the pump is activated to increase blood flow downstream of the pump. The pump can also be positioned in the vena cava or used to treat right-sided heart failure following the insertion of an LVAD, or to improve venous return in patients with varicose veins. Non-stent pumps are described for insertion between the pulmonary vein and aorta, and between the vena cava and pulmonary artery designed for use during cardiac surgery.
