Patent number: 9529972Abstract: An indication that a patient event occurred may be used to evaluate the efficacy of at least one therapy program and/or adjust therapy delivery to the patient. In some examples, the patient event indication includes patient input that may be received via an event indication button of a programming device. In addition to or instead of the patient input, the patient event indication may be generated based on a physiological parameter of the patient. In some examples, therapy delivery may be adjusted by adjusting at least one therapy parameter value, switching therapy programs or therapy program groups or restarting a therapy cycle of a medical device. The patient input via an event indication button may also help evaluate whether a therapy system is useful for the patient.Type: GrantFiled: September 23, 2008Date of Patent: December 27, 2016Assignee: Medtronic, Inc.Inventors: Jonathon E.

Publication number: 20120330273Abstract: An implantable medical device for producing a variable therapeutic output to a patient. A therapeutic output delivery module requires replenishment following delivery of a predetermined amount of the therapeutic output. A calculator is responsive to a measure of an amount of the therapeutic output actually delivered to the patient for determining a parameter representative of a time at which the therapeutic output delivery module of the implantable medical device should be replenished with the therapeutic substance based at least in part upon the amount obtained from the measure. A method determines a parameter representative of a time at which a therapeutic output module of an implantable medical device should be replenished following delivery of a predetermined amount of therapeutic output. An amount of the therapeutic output actually delivered to the patient is measured. The parameter is calculated based at least in part upon the amount obtained in the measuring step.Type: ApplicationFiled: September 5, 2012Publication date: December 27, 2012Inventors: David C.

Patent number: 7008413Abstract: A generic treatment protocol is disclosed for therapeutically treating a patient via an implantable treatment device. Treatment steps can be defined to start and end at absolute times, or can be programmed via telemetry to start a certain amount of time after termination of a previously executed treatment step. Treatment steps have a treatment rate or dose attribute and a duration attribute. Treatment steps may optionally enable patient-activated bolus overlays. Patient-activated rate or dosage adjustments can also optionally be enabled. Repeated-execution treatment-step groups are also provided. Such treatment-step groups can have start and end times, a group duration, and a group total dose, each defined in a manner similar to that for a treatment step. Treatment-step groups include a repetition count, which could be set to a value that causes the group to repeat forever.Type: GrantFiled: June 11, 2003Date of Patent: March 7, 2006Assignee: Medtronic, Inc.Inventors: Peter J.
