Patent Issued for Configurable Medical Telemetry Radio System

August 25, 2014

By a News Reporter-Staff News Editor at Cardiovascular Week -- From Alexandria, Virginia, NewsRx journalists report that a patent by the inventors Carpenter, Greg (Centerville, MN); Bange, Joseph E. (Egan, MN); Musto, Peter J. (Prior Lake, MN); Mass, William R. (Maple Grove, MN); Hedstrom, Jonathan (Grand Marais, MN), filed on May 3, 2006, was published online on August 12, 2014 (see also Cardiac Pacemakers, Inc.).

The patent's assignee for patent number 8805526 is Cardiac Pacemakers, Inc. (St. Paul, MN).

News editors obtained the following quote from the background information supplied by the inventors: "Implantable medical devices (IMDs) are devices designed to be implanted into a patient. Some examples of these devices include cardiac function management (CFM) devices such as implantable pacemakers, implantable cardioverter defibrillators (ICDs), cardiac resynchronization devices, and devices that include a combination of such capabilities. The devices are typically used to treat patients using electrical or other therapy and to aid a physician or caregiver in patient diagnosis through internal monitoring of a patient's condition. The devices may include one or more electrodes in communication with sense amplifiers to monitor electrical heart activity within a patient, and often include one or more sensors to monitor one or more other internal patient parameters. Other examples of implantable medical devices include implantable diagnostic devices, implantable sensors, implantable insulin pumps, devices implanted to administer drugs to a patient, or implantable devices with neural stimulation capability.

"Typically, IMDs communicate wirelessly with an external device. Examples include an IMD programmer that provides bi-directional communication between the IMD and a caregiver, a patient activator that allows a patient to activate an implantable device, a patient data display that reads and displays information from the IMD, and a repeater that communicates with a network and locally communicates information with the IMD. The communication typically follows a protocol of information transfer defined by the IMD type. To communicate with more than one type of IMD, a physician may need more than one type of external programmer or other external device."

As a supplement to the background information on this patent, NewsRx correspondents also obtained the inventors' summary information for this patent: "This document discusses, among other things, systems and methods for communicating with implantable medical devices. A system example includes an external medical data telemetry device to communicate with an implantable medical device (IMD). The external medical data telemetry device includes a processor, a reconfigurable radio-frequency (RF) transceiver circuit, at least one far-field antenna, and a user interface. The reconfigurable RF transceiver circuit modulates an outgoing IMD data signal and demodulates an incoming IMD data signal using a modulation type that is selectable from a plurality of modulation types by the processor. The processor selects the modulation type using information entered by a user through the user interface.

"A method example includes receiving an input through a user interface of an external telemetry device, identifying an implantable medical device (IMD) type using the input, selecting at least one far-field radio frequency (RF) modulation type in the external telemetry device from a plurality of modulation types selectable in the external telemetry device using the IMD type, and modulating or demodulating one or more data signals outgoing or incoming to an IMD, using the external telemetry device and the selected modulation type.

"This summary is intended to provide an overview of the subject matter of the present patent application. It is not intended to provide an exclusive or exhaustive explanation of the invention. The detailed description is included to provide further information about the subject matter of the present patent application."
