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: 9956412Abstract: The disclosure is directed towards posture-responsive therapy. To avoid interruptions in effective therapy, an implantable medical device may include a posture state module that detects the posture state of the patient and automatically adjusts therapy parameter values according to the detected posture state. A system may include a user interface that receives user input linking a plurality of posture states of a patient, and selecting a set of therapy parameter values for delivery of therapy to the patient for each of a linked posture states, a processor that defines the therapy to be delivered to the patient for each of the linked posture states based on the selection, and an implantable medical device that delivers the therapy to the patient for each of the linked posture states based on the selection.Type: GrantFiled: April 30, 2009Date of Patent: May 1, 2018Assignee: Medtronic, Inc.Inventors: Dennis M.

Patent number: 9937342Abstract: The disclosure provides techniques for parameter-directed shifting of electrical stimulation electrode combinations. An external programmer permits a user to shift electrode combinations, e.g., along the length of a lead or leads. The external programmer accepts shift input and causes an electrical stimulator to shift electrode combinations as indicated by the input. Different sets of electrodes may have different electrode counts. For example, an array of electrodes carried by one lead may have a greater number of electrodes than an array of electrodes carried on another lead. The disclosure provides techniques for shifting electrode combinations among leads with different electrode counts. For example, an external programmer may execute shifts in a series of shift operations, where the number of shift operations along the length of a lead having a greater electrode count is greater than the number of shift steps along the length of a lead having a lesser electrode count.Type: GrantFiled: April 28, 2008Date of Patent: April 10, 2018Assignee: Medtronic, Inc.Inventors: Dennis M. Skelton, Joseph J. Nolan, Nathan A. Torgerson, Wende L. Dewing, Todd V. Smith, Shyam Gokaldas, Steven M. Goetz, Andrew H. Houchins, Jeffrey T. Keacher

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: 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. Skelton, Jon P. Davis, Rajeev M. Sahasrabudhe, Shyam Gokaldas, Joseph J. Nolan

Patent number: 9149210Abstract: 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 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: April 28, 2010Date of Patent: October 6, 2015Assignee: MEDTRONIC, INC.Inventors: Rajeev M. Sahasrabudhe, Lynn Davenport, Jon P. Davis, Wende L. Dewing, Elizabeth A. Fehrmann, Steven Goetz, Shyam Gokaldas, Eric J. Panken

Patent number: 8996123Abstract: Various programming techniques are described for medical devices that deliver electrical stimulation therapy that may include mapping between discrete electrical stimulation parameters and a graphical view of the electrical stimulation representing a stimulation zone generated by the parameters. In one example, a method includes receiving, via a programmer for an electrical stimulator, user input that graphically manipulates at least one of size and a shape of a graphical representation of at least one electrical stimulation zone displayed on the programmer, and defining a program to control delivery of electrical stimulation therapy based on the user input.Type: GrantFiled: October 18, 2010Date of Patent: March 31, 2015Assignee: Medtronic, Inc.Inventors: Steven M.
