Patent number: 8352042Abstract: A method of preventing inadvertent signal transmission sent from a remote control for controlling the operation of an implantable infusion device. The method includes maintaining the remote control in a locked state prior to a user intentionally unlocking the remote control in order to generate transmission of a signal from the remote control to the implantable infusion device. The unlocking of the remote control can include moving a button control element, unlocking a button lock, pressing a button other than the signal generation button, pressing the signal generation button in a specific sequence or shaking the remote control.Type: GrantFiled: November 28, 2006Date of Patent: January 8, 2013Inventors: Stephen D. Das, Jose P. Bernardo, Daniel H. Villegas, Scott R. Gibson, Timothy John Payne, Scott LaVoy Conway, Joseph Wayne Vandegriff

Publication number: 20110275904Abstract: A communication device (CD) exchanges messages with an implantable infusion pump via telemetry such that commands are supplied thereto and operational information is obtained therefrom. The CD is controlled, at least in part, by a processor IC according to a software program operating therein and provides feedback to a user via a visual display, an audio alarm, and a vibrational alarm, and allows input from the user via a touch sensitive keypad. Certain input functions are restricted by password. The visual display includes an icon and fixed element display region and a bitmap display region. The fixed element display region includes time and date displays, battery and drug level displays that decrement, and a moving delivery state display. Various screens allow operational or log information to be displayed and/or user entry of commands. Program features when disabled are removed from a series of screen options that can be scrolled through.Type: ApplicationFiled: March 2, 2011Publication date: November 10, 2011Inventors: Ronald J. Lebel, Varaz Shahmirian, Daniel H. Villegas, David Y. Choy, Philip T. Weiss, Paul M. Meadows

Publication number: 20080177254Abstract: The present invention relates to an implantable drug delivery device which includes a fluid drug reservoir, a catheter, a controllable fluid transfer device, e.g., a pump or valve, and a drug delivery control means. The control means in accordance with the invention is configured to initially clear a first, or old, drug from the device based on the content of the Current Profile data containing a first, or old, delivery profile. After the old drug is cleared, then the control means automatically modifies the Current Profile data to match a second, or new, delivery profile for controlling delivery of a second, or new, drug.Type: ApplicationFiled: October 29, 2007Publication date: July 24, 2008Inventors: Brian M. Shelton, Ronald J. Lebel, Daniel H. Villegas

Patent number: 7171274Abstract: An implanted medical device (e.g. infusion pump) and handheld communication device communicate with one another via telemetry wherein transmitted messages have enhanced numbers of and/or regularity of bit transitions to minimize the risk of synchronization loss between transmitted bits of data and received bits of data. Bit transitions for portions of messages may be enhanced by applying a pseudo-randomization scheme to those portions of messages that are transmitted in a way that allows the receiver to extract the original data from the received randomized data. Preferred randomization techniques modify (i.e. randomize) the data using a CRC value that is being accumulated while simultaneously causing the modified data to modify subsequent accumulation of the CRC itself. Upon reception, the reversal of data randomization occurs so that the intended message is appropriately received.Type: GrantFiled: May 12, 2003Date of Patent: January 30, 2007Assignee: Medtronic Minimed, Inc.Inventors: Timothy J. Starkweather, Ronald J. Lebel, Daniel H. Villegas, Philip T. Weiss, John T. Armstrong, John D. Richert

Ambulatory medical apparatus and method using a telemetry system with predefined reception listening
Patent number: 6950708Abstract: An implanted medical device (e.g. infusion pump) and an external device communicate with one another via telemetry messages that are receivable only during windows or listening periods. Each listening period is open for a prescribed period of time and is spaced from successive listening periods by an interval. The prescribed period of time is typically kept small to minimize power consumption. To increase likelihood of successful communication, the window may be forced to an open state, by use of an attention signal, in anticipation of an incoming message. To further minimize power consumption, it is desirable to minimize use of extended attention signals, which is accomplished by the transmitter maintaining an estimate of listening period start times and attempting to send messages only during listening periods. In the communication device, the estimate is updated as a result of information obtained with the reception of each message from the medical device.Type: GrantFiled: July 29, 2002Date of Patent: September 27, 2005Assignee: Medtronic Minimed, Inc.Inventors: Sam W. Bowman IV, Ronald J. Lebel, Daniel H. Villegas, John C. Gord -
