Publication number: 20100023076Abstract: The disclosure describes techniques for protecting patient data stored in a medical device, such as an external defibrillator. The patient data may be transferred, or downloaded, from the medical device to another device, such as to a computing device for storage or analysis. In response to the download, the medical device may protect the patient data so that at least subset of users can no longer access the patient data. Patient data may be protected by modifying the data form, encrypting the data, moving the data to another memory module, password protecting the patient data, or modifying an access control list associated with the patient data. While the patient data may also be deleted as a technique for protecting the data, not deleting the data may allow the data to be recovered at a later time by an authorized user, i.e., a user not part of the subset.Type: ApplicationFiled: October 6, 2009Publication date: January 28, 2010Applicant: Medtronic Emergency Response Systems, Inc.Inventor: Steven B.

Publication number: 20100016910Abstract: Methods and apparatus are provided for determining a defibrillation treatment protocol in an external defibrillator using a measurement of elapsed time. The present invention provides a defibrillator with a timer function. Upon activation of the defibrillator, an internal timer begins to run. By closely associating the activation of the defibrillator with the onset of the patient's attack, and by making allowances for inherent time differences between these events, the timer provides a measure of the elapsed time between the onset of the patient's emergency and the presentation of the defibrillator at the patient's side. Using this measure of elapsed time, the defibrillator determines an appropriate treatment therapy, such as CPR or defibrillation therapy.Type: ApplicationFiled: September 25, 2009Publication date: January 21, 2010Applicant: Medtronic Emergency Response Systems, Inc.Inventors: Joseph L. Sullivan, Fred W. Chapman, Daniel W. Piraino

Publication number: 20080004663Abstract: In general, the invention is directed to techniques for using an external defibrillator to detect a presence of an implantable medical device (IMD) implanted within a patient, and providing therapy to the patient through communication between the external defibrillator and the IMD. An external defibrillator provides prompts to a user of the external defibrillator to determine the presence of an IMD implanted within the patient. For example, the external defibrillator may prompt the user to visually inspect the patient's chest for signs that an IMD was implanted, such as a scar or raised portion of skin near the patient's clavicles. As another example, the external defibrillator may prompt the user to place a detection device on the patient's chest. The detection device may be coupled to the external defibrillator, and may employ a magnet to initiate telemetry by the IMD to detect the presence of the IMD.Type: ApplicationFiled: December 22, 2005Publication date: January 3, 2008Applicant: Medtronic Emergency Response Systems, Inc.Inventor: David Jorgenson

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.

Publication number: 20060167515Abstract: Signal data obtained from a piezoelectric sensor placed on a patient's body is used to detect the presence of a cardiac pulse. The piezoelectric sensor has a transducing element adapted to sense movement due to a cardiac pulse and produce piezoelectric signal data in response thereto. Processing circuitry analyzes the piezoelectric signal data for a feature indicative of a cardiac pulse and determines whether a cardiac pulse is present in the patient based on the feature. In one aspect, the feature may be a temporal feature such as a relative change in energy. In another aspect, the feature may be a spectral feature such as the energy or frequency of a peak in the energy spectrum of the signal. In yet another aspect, the feature may be obtained by comparing the piezoelectric signal data with a previously-identified pattern known to predict the presence of a cardiac pulse. Multiple features may also be obtained from the piezoelectric signal data and classified to determine the presence of a cardiac pulse.Type: ApplicationFiled: July 22, 2005Publication date: July 27, 2006Applicant: Medtronic Emergency ResponseInventors: Ronald Stickney, Cynthia Jayne, Paula Lank, Patricia O'Hearn, Tae Joo, David Hampton, Richard Nova, Patrick Kelly, William Saltzstein

Patent number: 7056282Abstract: The invention is directed to techniques and apparatus for controlling the temperature of a coolant delivered to a patient in a hypothermic therapy system, including a hypothermic therapy system that can be applied to a patient outside or inside a hospital setting. In general, the coolant is in a pressurized form at ambient temperature, and is expanded proximate to the patient to cause the coolant to cool. Cooling garments placed in contact with the body of the patient circulate the cooled coolant proximate to the patient to cool the patient. A controller controls the temperature of the coolant by mixing the coolant with ambient air, for example, to reduce the risk of harm the patient.Type: GrantFiled: July 31, 2003Date of Patent: June 6, 2006Assignee: Medtronic Emergency Response Systems, Inc.Inventors: Steven M.
