Patent number: 8116864Abstract: An apparatus and techniques for determining whether a medical electrode, such as a defibrillation electrode coupled to an automated external defibrillator, is in a condition for replacement. The determination can be made as a function of one or more data. In one exemplary embodiment, the determination is a function of one or more measurements of an impedance of a hydrogel bridge in a test module. In another exemplary embodiment, the determination is a function of one or more environmental condition data from one or more environmental sensors.Type: GrantFiled: December 10, 2008Date of Patent: February 14, 2012Assignee: Physio-Control, Inc.Inventors: Kevin K. Covey, Thomas J. McGrath, Joseph L. Sullivan, Larry R. Nygaard, Richard C. Nova

Patent number: 7179279Abstract: In general, the disclosure presents techniques for rapidly cooling the body of a patient. A cooling garment is placed in contact with the body of the patient. Spacers within the cooling garment create a space between at least a portion of the cooling garment and the body of the patient. The cooling garment receives a coolant from a coolant supply and delivers the coolant to the body of the patient. The heat from the body of the patient may evaporate the coolant. A carrier gas, which circulates within the space between the cooling garment and the patient, carries the gaseous coolant out of the cooling garment via an exit port. The rapid cooling of the patient may slow the neurological damage to the patient.Type: GrantFiled: September 30, 2002Date of Patent: February 20, 2007Assignee: MedTronic Physio Control Corp.Inventors: Stephen W. Radons, Larry R. Nygaard, Martin S. Abbenhouse, Steven M. Chester

Patent number: 7087075Abstract: In general, the disclosure presents techniques for control of a cooling garment in response to a signal that is a function of a patient parameter such as body temperature. In particular, a cooling garment that receives a coolant and a carrier gas is placed in contact with the body of a patient. A sensor within the cooling garment may generate a signal as a function of a patient parameter. A controller receives the signal via communication link, and may send a signal to a regulator that may regulate delivery of the coolant and/or carrier gas, for example.Type: GrantFiled: September 30, 2002Date of Patent: August 8, 2006Assignee: Medtronic Emergency Response Systems, Inc.Inventors: Kathleen E. Briscoe, Stephen W. Radons, Larry R. Nygaard, Joseph L. Sullivan

Publication number: 20040162586Abstract: Electrodes having electrode identification tags are used on medical devices, particularly on defibrillators. One such defibrillator uses electrical devices to query the tags and acquire electrode identification information. Software is also incorporated for querying the tags automatically and interpreting the acquired information.Type: ApplicationFiled: April 25, 2003Publication date: August 19, 2004Inventors: Kevin K. Covey, Larry R. Nygaard
