Patent number: 10204706Abstract: In one aspect, a programmer for an implantable medical device comprises a user interface that receives user input corresponding to one or more selected stimulation therapy parameters for delivering stimulation therapy to a patient with the implantable medical device and presents an energy consumption estimate of a power source based on the selected stimulation therapy parameters; and a processor that determines one or more programming options that, if selected, would alter the selected stimulation therapy parameters and reduce the energy consumption estimate. The user interface presents at least one of the programming options to reduce the energy consumption estimate to the user with an indication that user selection of one or more of the presented programming options would alter the selected stimulation therapy parameters to reduce energy consumption of the implantable medical device.Type: GrantFiled: April 30, 2010Date of Patent: February 12, 2019Assignee: Medtronic, Inc.Inventors: Jon P.

Patent number: 9956418Abstract: The disclosure provides a system that displays graphical representations of posture zones associated with posture states of a patient, on a display device communicatively coupled to a medical device. The medical device is configured to deliver therapy to the patient based on detected posture states of the patient, where the detected posture state is based on the posture zones. The display device may allow a user to manipulate the graphical representations of the posture zones, including changing the size of the posture zones. Additionally, the display device may allow a user to change transition times associated with transitions between posture states, and displaying an indication of the changed transition time by highlighting the two graphical representations of the posture zones corresponding to the posture states associated with the changed transition time.Type: GrantFiled: January 6, 2011Date of Patent: May 1, 2018Assignee: Medtronic, Inc.Inventors: Jon P.

Patent number: 9919159Abstract: A programming session for an implantable medical device that includes a posture responsive therapy mode includes at least two phases. In a first phase, a first set of therapy parameter values are modified while the posture responsive therapy mode is deactivated. In the posture responsive therapy mode, the medical device automatically selects one or more therapy parameter values that define therapy delivered to a patient based on a detected posture state. In a second phase, the posture responsive therapy mode is activated and a second set of therapy parameter values are adjusted after observing a patient response to the posture responsive therapy delivered with the first set of therapy parameter values selected during the first phase. The second set of therapy parameter values may, for example, define the patient posture states or the modification profiles with which the medical device adjusts therapy upon detecting a posture state transition.Type: GrantFiled: September 7, 2016Date of Patent: March 20, 2018Assignee: Medtronic, Inc.Inventors: Dennis M.

Patent number: 9744365Abstract: This disclosure is related to techniques for presenting therapy factors related to medical device therapy in a manner that allows a user, such as a patient or a clinician, to receive, comprehend and evaluate information relating to therapy delivered by the medical device efficiently. In one aspect, a method comprises obtaining a data set corresponding to a therapy factor associated with delivery of a medical therapy to a patient with a medical system including an implantable medical device, receiving a user selection associated with a subset of the data set, the subset of the data set including less than all the information relating to the therapy factor in the data set, and presenting a representation, corresponding to the subset of the data set, of the therapy factor on a display of a programmer.Type: GrantFiled: January 7, 2011Date of Patent: August 29, 2017Assignee: Medtronic, Inc.Inventors: Jon P.

Patent number: 9622700Abstract: Techniques relate to operating a medical device by classifying a detected posture state of a patient. This classification may be performed by comparing the detected posture state of the patient to posture state definitions available within the system. Each definition may be described in terms of a parameter (e.g., vector) indicative of a direction in three-dimensional space. The posture state definitions may be calibrated by automatically estimating values for these parameters, thereby eliminating the need for the patient to assume each posture state during the calibration process to capture actual parameter values. According to another aspect, the estimated parameter values may be updated as the patient assumes various postures during a daily routine. For instance, estimated vectors initially used to calibrate the posture state definitions may be changed over time to more closely represent posture states the patient actually assumes, and to further adapt to changes in a patient's condition.Type: GrantFiled: October 1, 2015Date of Patent: April 18, 2017Assignee: Medtronic, Inc.Inventors: Rajeev M. Sahasrabudhe, Lynn A. Davenport, Jon P. Davis, Wende L. Dewing, Elizabeth A. Fehrmann, Steven M. Goetz, Shyam L. Gokaldas, Eric J. Panken

Patent number: 9272091Abstract: The disclosure provides a system that displays a posture state indication to a user. A posture state indication represents the current posture state of the patient, which may be a combination of patient posture and activity. As a patient changes posture and activity throughout a daily routine, a posture state detector may generate a posture state value that may be used to categorize the patient's posture or posture and activity level as one of multiple posture states used to adjust therapy. The posture state may be associated with one of multiple posture state indications that may be presented to the patient. The posture state indication shows the patient the posture state currently detected by the posture state detector. The posture state indication may help the patient to effectively monitor therapy changes due to automatic, semi-automatic or patient-directed therapy adjustments made as a function of posture state.Type: GrantFiled: April 29, 2015Date of Patent: March 1, 2016Assignee: MEDTRONIC, INC.Inventors: Dennis M.

Patent number: 8751010Abstract: A system and method for determining, during a recharge session, an amount of time until a subsequent recharge session is required to charge a rechargeable power source of an implantable medical device. A model allows a determination of the time until recharge without suspending charging during the recharge session by basing the determination on an initial measured battery voltage and a present current into the rechargeable power source. Alternatively, charging is suspended during the recharge session, and voltage measurements are taken, after which time charging is resumed, without patient input or suspending the recharge session.Type: GrantFiled: April 30, 2008Date of Patent: June 10, 2014Assignee: Medtronic, Inc.Inventors: John C.
