Abstract: A hydration management system includes a console for mounting on an IV pole. A urine collection bag and a hydration fluid bag hang from the console. Urine in the urine collection bag is weighed. An infusion pump is configured to pump hydration fluid from the infusion bag. A controller is responsive to the weight of the urine collection bag and controls the infusion pump to hydrate the patient based on the patient's urine output. An infusion set includes an infusion bag connector, an IV needle connector, and tubing, placed in the infusion pump, extending between the infusion bag connector and the IV needle connector. A urine collection set typically includes the urine collection bag, a catheter connector, and tubing extending between the urine collection bag connector and the catheter connector.

Abstract: A patient hydration system with an infusion subsystem responsive to a source of hydration fluid for infusing the patient with hydration fluid. A urine output measurement subsystem determines the amount of urine output by the patient. A setting is received corresponding to an amount of urine to be output by the patient. When or after the urine output measurement subsystem indicates the set amount of urine has been output by the patient, the infusion subsystem is controlled to administer hydration fluid to the patient based on the patient's further urine output.

Abstract: A patient hydration system with a patient urine output measurement device, a hydration fluid administration subsystem, and a controller, responsive to the patient urine output measurement device. The controller is configured to control the hydration fluid administration subsystem to administer hydration fluid to the patient to prevent dehydration of the patient. A hydration sensor is also included to detect at least one patient parameter indicative of the patient's hydration state.

Abstract: An endovascular tissue removal device including a lumen including a rotatable terminal hub advanceable in vasculature, at least one fiber extending from the hub for ablating tissue, and an expandable mechanism connected to the fiber for biasing it into position for precisely ablating tissue as the hub rotates.

Abstract: An endovascular tissue removal system including an expandable mechanism introduceable to the ventricular side of a valve to support the leaflets of the valve in a closed position and a tissue removal device advanceable to the leaflets and configured to resect the leaflets as they are supported by the expandable mechanism.

Abstract: An endovascular tissue removal device including a lumen with a distal steerable tip portion extending from a joint portion, registration means for holding the joint portion fixed in place in the vasculature, and a source of ablation energy in communication with the lumen whereby tissue can be resected by ablation energy as the tip portion is steered within the vasculature.
