Patent number: 10289280Abstract: A device for programming an implantable fluid delivery device receives a therapeutic agent concentration, wherein the therapeutic agent concentration comprises a mass of the therapeutic agent per unit of volume. The device further determines a reference rate value based on the received therapeutic agent concentration, wherein the reference rate value comprises a mass per unit of time. The device additionally displays a graphical user interface comprising a horizontal axis and a vertical axis, wherein the horizontal axis represents time and the vertical axis represents rates of delivery of the fluid by the implantable fluid delivery device. The maximum value of the vertical axis displayed in the graphical user interface is determined based on the determined reference rate value and is determined to be less than a maximum therapeutic agent infusion rate.Type: GrantFiled: June 7, 2013Date of Patent: May 14, 2019Assignee: Medtronic, Inc.Inventors: Ajinkya M.

Patent number: 7797047Abstract: An implantable medical device (IMD) includes a lead status monitoring system. The lead status monitoring system employs a method including the steps of: collecting data sets from a lead impedance source, a stimulation threshold source, and at least one additional source included in the IMD; and processing the data sets to determine if a lead status event has occurred.Type: GrantFiled: February 18, 2004Date of Patent: September 14, 2010Assignee: Medtronic, Inc.Inventors: David J.

Patent number: 7738959Abstract: Undersensing of an evoked response during an automatically initiated search of the stimulation threshold in a stimulation channel of an IMD, e.g., the pacing threshold in a pacing channel of a pacing system, is minimized by repeating the search using the sense amplifier of the stimulation channel configured in bipolar and unipolar sensing configurations. A failure to sense an evoked response in the search in one sensing configuration can be confirmed, and stimulation energy set to a high output, if an evoked response is not sensed in an alternate sensing configuration or refuted if an evoked response is sensed in the alternate sensing configuration. If the failure is refuted, the alternate sensing configuration is employed until the next search.Type: GrantFiled: September 30, 2002Date of Patent: June 15, 2010Assignee: Medtronic, Inc.Inventors: Christopher M. Manrodt, Todd J. Sheldon, Bradley C. Peck

Patent number: 6445952Abstract: An apparatus and method for detecting micro-dislodgment at a heart tissue/pacing lead electrode interface involves measuring a first pacing threshold parameter at a first time in a patient's cardiac cycle and measuring a second pacing threshold parameter at a second time in the patient's cardiac cycle. Micro-dislodgment occurring at the heart tissue/pacing lead electrode interface is detected using the first and second pacing threshold parameters. Micro-dislodgment may be detected by comparing a difference between, or a ratio of, the first and second pacing threshold parameters to a preestablished maximum allowable deviation value. A difference between the first and second pacing threshold parameters or a ratio in excess of the preestablished maximum allowable deviation value indicates a problem at the heart tissue/pacing lead interface.Type: GrantFiled: May 18, 2000Date of Patent: September 3, 2002Assignee: Medtronic, Inc.Inventors: Christopher M.

Patent number: 6317633Abstract: An implantable medical device (IMD) coupled with leads extending to body tissue providing storage of lead related data, monitoring of lead functional status, and indication of lead integrity to the clinician. A lead status monitor (LSM) processes lead related data in a system self test mode and provides a lead status report that identifies and declares conductor/connector issues, insulation issues, and electrode/tissue interface issues indicative of suspected lead related condition mechanisms for each lead employed in the IMD. The LSM operates employing a set of LSM rules that process measured lead impedance values and loss of capture (LOC) values. In a pacing system, particular LSM rules are defined that process periodically determined, pacing pulse characteristic at LOC and bipolar and unipolar lead impedance values that are measured periodically. The lead impedance values are compared to upper and lower limits or trip points of a normal impedance range.Type: GrantFiled: January 19, 2000Date of Patent: November 13, 2001Assignee: Medtronic, Inc.Inventors: David J.

Patent number: 6163724Abstract: A software programmable device means such as a microprocessor discriminates between evoked response signals and post-pace polarization signals sensed by an implantable medical device. The polarity of the positive or negative change in voltage in respect of time (or dv/dt) of the waveform incident on the lead electrodes is monitored during a short period of time immediately following a paced event. It has been discovered that the post-pace polarization signal exhibits a relatively constant polarity during the capture detect window, and that the evoked response signal may cause the polarity of post-pace polarization signal to reverse during the capture detect window . The sign of the post-pace polarization polarity, either positive or negative, is determined by the design of the specific output circuitry. The evoked response signal may reverse the polarity of the sensed signal in either case, from positive to negative or from negative to positive, during the time window of interest.Type: GrantFiled: August 27, 1999Date of Patent: December 19, 2000Assignee: Medtronic, Inc.Inventors: Michael Todd Hemming, Bradley C.
