Publication number: 20170026822Abstract: Methods and systems for media access control allow master and slave nodes of a network to communicate using the same carrier while avoiding collisions of transmissions. At least one slave node is an implantable device. Master nodes initiate all data exchange sequences, and slave nodes are responsive to the data exchange sequences. The exchange sequences begin by master nodes contending for use of the carrier through a countdown procedure. A set order of communications occurs between a master node who won the contention and a slave node being communicated with by the master node to transfer a data frame. Contention is then repeated to determine the next master node that is allowed to transfer a data frame. New master nodes entering the network employ a discovery process to poll for existing devices in the network.Type: ApplicationFiled: October 6, 2016Publication date: January 26, 2017Inventors: Joseph E. Bange, Allan T. Koshiol, Paul Holmquist, Karen M. Kramer, Thomas Harris

Patent number: 9269251Abstract: A communicator facilitates communications with a remote server via a wireless network supporting a plurality of disparate data transport mechanisms having differing characteristics. A processor coupled to memory is disposed in a communicator housing, which is configured for portability. The memory stores wireless radio firmware and data transfer instructions that are executable by the processor for transferring data to the remote server in accordance with a priority level. The priority level is based in part on criticality of the data and the communicator status. A radio disposed in the housing effects communications via the wireless network in accordance with the firmware. A power source in the housing supplies power for communicator components. The processor executes program instructions for selecting a data transport mechanism among the plurality transport mechanisms based on the priority level, and transmits the data via the wireless network via the radio using the selected transport mechanism.Type: GrantFiled: December 19, 2014Date of Patent: February 23, 2016Assignee: Cardiac Pacemakers, Inc.Inventors: John LaLonde, William R.

Patent number: 8768483Abstract: A system and method for receiving telemetry data from implantable medical devices such as cardiac pacemakers with improved noise immunity is disclosed. Ambient noise levels and signal strength are monitored and used to adaptively adjust the detection sensitivity of the receiver. Filtering of the received signal is performed to remove both broadband and narrowband noise. Removal of narrowband noise is accomplished with notch filters that are dynamically adjusted in accordance with a detected noise spectrum.Type: GrantFiled: June 19, 2013Date of Patent: July 1, 2014Assignee: Cardiac Pacemakers, Inc.Inventors: Steven Schmitt, Fred Schleifer, Joseph E.

Patent number: 8704688Abstract: Physiological data is generated from signals received from one or more leads associated with the IMD. The physiological data is sampled to generate a plurality of data samples. A predictive encoding algorithm is applied to the plurality of data samples to generate a plurality of encoded data samples each corresponding to one of the plurality of data samples. An entropy encoding algorithm is then applied to the plurality of encoded data samples to generate a plurality of code words each corresponding to one of the plurality of encoded data samples. The code words are then stored in a memory in the IMD.Type: GrantFiled: March 20, 2012Date of Patent: April 22, 2014Assignee: Cardiac Pacemakers, Inc.Inventors: Zhe Shen, Joseph E. Bange, Allan T.

Patent number: 8706251Abstract: A method and system for enabling secure communications between an implantable medical device (IMD) and an external device (ED) over a telemetry channel. A telemetry interlock may be implemented which limits any communications between the ED and the IMD over the telemetry channel, where the telemetry interlock is released when the ED transmits an enable command to the IMD via a short-range communications channel requiring physical proximity to the IMD. As either an alternative or addition to the telemetry interlock, a data communications session between the IMD and ED over the telemetry channel may be allowed to occur only after the IMD and ED have been cryptographically authenticated to one other.Type: GrantFiled: December 18, 2006Date of Patent: April 22, 2014Assignee: Cardiac PacemakersInventors: Jeffrey A.
