Publication number: 20040162584Abstract: A method of performing a medical procedure, such as surgery, is provided. A nerve is stimulated in order to adjust the beating of the heart to a first condition, such as a stopped or slowed condition. The medical procedure is performed on the heart or another organ. The stimulation of the nerve is stopped in order to adjust the beating of the heart to a second condition, such as a beating condition. The heart itself may also be stimulated to a beating condition, such as by pacing. The stimulation of the nerve may be continued in order to allow the medical procedure to be continued. Systems and devices for performing the medical procedure are also provided.Type: ApplicationFiled: February 12, 2004Publication date: August 19, 2004Inventors: Michael R. S. Hill, Scott E. Jahns, James R. Keogh, David E. Euler, Michael R. Ujhelyi, Nancy J. Rakow, Michael A. Colson

Patent number: 4458693Abstract: Apparatus and technique for monitoring physiological parameters. An acoustic sensor or microphone is placed in close proximity to the chest of a patient having one or two prosthetic heart valves. These heart valves produce clicks characteristic of opening and closing action. The acoustic sensor picks up the sound of these clicks and transfers them as electrical energy to a transmitter unit. The transmitter unit processes the analog signal, converts it to a digital signal and establishes the key timing factors involved. This digital data is stored in a memory buffer within the transmitter. Subsequently, this information is modulated and placed on telephone lines for transmission to a central monitoring site. At the monitoring site a demodulator returns the data to baseband digital signals. A computer at the central monitoring site displays the information in the time domain and also converts the information for display in the frequency domain.Type: GrantFiled: March 13, 1981Date of Patent: July 10, 1984Assignee: Medtronic, Inc.Inventors: John D. Badzinski, Michael A. Colson, Dennis G. Hepp
