A heart-synchronized pulsed laser system includes a laser; means for sensing the contraction and expansion of a beating heart to be synchronized with the laser; means, responsive to the means for sensing, for generating a trigger pulse; means for positioning the leading edge of the trigger pulse; means for positioning the leading edge of the trigger pulse during the contraction and expansion cycle of the heartbeat; means for defining the width of the trigger pulse to occur during the heartbeat cycle; and means responsive to the trigger pulse for firing the laser to strike the beating heart at the time indicated by the trigger pulse position and for the period indicated by the width of the trigger pulse. In addition, the invention feature a handpiece for a medical laser system comprising a barrel for having a passage for transmitting a laser beam and a contacting wall on one end of said barrel including an aperture in communication with the passage, a solid face extending radially outward from the aperture to the periphery of said contacting wall, and a knurled surface on the face for preventing movement of the contacting wall with respect to the heart wall during surgery.

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.

A heart-synchronized vacuum-assisted pulsed laser technique generates a valve control signal in response to the ECG of a beating heart which is to be synchronized with the laser; the valve control signal is applied to a valve to open it and permit laser gas to be delivered to the gas inlet of the laser assisted by the draw from a vacuum source at the gas outlet of the laser, to produce a predetermined range of laser gas pressure in the laser; the valve control signal is ceased after the predetermined range of laser gas pressure has been reached to end the gas flow through the laser and enable the rebuilding of the vacuum in the vacuum source; and a laser firing signal is generated to fire the laser when the laser gas pressure is in the predetermined range.
