Patent number: 8827913Abstract: An example system may include at least one pressure sensor configured to measure a cardiovascular pressure signal and another medical device configured to measure an electrical depolarization signal of the heart. The system determines a plurality of cardiovascular pressure metrics based on the measured cardiovascular pressure signal, including at least one cardiovascular pressure metric indicative of a timing of at least one cardiac pulse. The system also determines a metric indicative of a timing of at least one heart depolarization within the measured electrical depolarization signal. The system compares the timing of the at least one cardiac pulse to the timing of the at least one depolarization, and determines whether to discard the plurality of cardiovascular pressure metrics based on whether the timings substantially agree.Type: GrantFiled: May 3, 2011Date of Patent: September 9, 2014Assignee: Medtronic, Inc.Inventors: William J.

Patent number: 8585604Abstract: A therapy regimen, e.g., a contingent medication prescription, may be created and automatically distributed to a patient via an integrated patient care system. A clinician may create therapy instructions by at least associating patient conditions with one or more therapy regimens, e.g., medication prescriptions. In some examples, the integrated patient care system may present historical condition data to the clinician to aid the clinician with creating and/or updating the therapy instructions specific to the patient. A therapy module of the integrated patient care system may use the therapy instructions to automatically select a therapy regimen from the therapy instructions based on a patient condition detected based on a sensed physiological parameter. The physiological parameter of the patient may be sensed by an implanted or external sensor. In some examples, the therapy regimen can be presented to the patient according to a predetermined schedule or in response to the detected condition.Type: GrantFiled: October 29, 2010Date of Patent: November 19, 2013Assignee: Medtronic, Inc.Inventors: Tommy D.
