A sonic transducer includes a transducer body and a drive element coupled to the transducer body to produce a sonic output in response to an applied electrical input. A sense element is coupled to the sonic drive element and is configured to provide an electrical feedback output related to the sonic output. The electrical feedback output is adapted to be used to control the applied electrical input to the sonic drive element so as to control the energy delivered to the working area or tip of the transducer.

The present invention provides an improved peritoneal dialysis method and system. The system comprises a single catheter that is placed in the patient, a source of dialysate, and a diatyzer in fluid communication with the source of dialysate and the catheter. The system includes a single fluid pump in fluid communication with the source of dialysate and the catheter. The single pump is capable of pumping the dialysate into and out of the patient and back to the source of dialysate. The method includes the steps of placing a single catheter in a peritoneum of the patient, providing a source of dialysate, coupling the source of dialysate in fluid communication with the catheter on a single fluid circuit, pumping the dialysate from the source of dialysate into and out of the peritoneum using a single pump in the single fluid circuit.

An automatic means and method for preventing and/or treating hypotension in hemodialysis patients. To this end, a system is provided wherein the patient or healthcare practitioner can cause the hemodialysis machine to automatically deliver sodium to the patient through the dialysate so as to increase blood and extracellular osmolarity, increase blood volume from vascular refilling, and raise blood pressure. This would thereby alleviate any clinical symptoms caused by hypotension during hemodialysis.
