| 20080215121 | SYSTEM AND METHOD FOR RF WAKE-UP OF IMPLANTABLE MEDICAL DEVICE - A telemetry system is presented for enabling radio-frequency (RF) communications between an implantable medical device and an external device in a manner which reduces the power requirements of the implantable device by duty cycling its RF circuitry. A wakeup scheme for the implantable device is provided in which the external device transmits a data segment containing a repeating sequence of special wakeup characters in order to establish a communications session with the implantable device. The wakeup scheme may be designed to operate in the context of a handshaking protocol for collision avoidance. | 09-04-2008 |
| 20090036942 | Method and system for identifying and displaying groups of cardiac arrhythmic episodes - A medical device system that receives cardiac data representing a plurality of stored arrhythmic episodes, and analyzing the cardiac data to identify and display a subset of stored arrhythmic episodes as a function of user-specified episode criteria. The medical device system presents a query window on an interactive display in order to receive user-specified episode criteria via one or more input fields. The medical device displays only those episodes matching the episode criteria such as arrhythmia type, zone of detection, date of occurrence and average heart rate in beats per minute (BPM). | 02-05-2009 |
| 20090296602 | METHODS AND SYSTEMS FOR PROVIDING MULTIPLE ACCESS WITHIN A NETWORK - 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. | 12-03-2009 |
| 20100234914 | IMPLANTABLE MEDICAL DEVICE DIAGNOSTIC DATA ACQUISITION AND STORAGE - A method carried out by a therapeutic implantable medical device includes detecting a plurality of physiologic episodes and recording a set of diagnostic data associated with the plurality of physiological episodes. The plurality of physiologic episodes are prioritized based on episode types associated with the physiologic episodes. The diagnostic data is analyzed based on a minimum and maximum number associated with each episode type relating to a minimum and maximum number of sets of diagnostic data to be recorded for the associated episode type. The recorded set of diagnostic data is deleted only if a later recorded set of diagnostic data is associated with a detected physiologic episode having an episode type of a higher priority, and deletion of the set of diagnostic data would not result in fewer sets of diagnostic data than the minimum number specified for the episode type associated with the set of diagnostic data. | 09-16-2010 |
| 20100268296 | CARDIAC RHYTHM MANAGEMENT SYSTEM WITH USER INTERFACE FOR THRESHOLD TEST - An implantable cardiac rhythm management system includes a user interface, such as an external programmer, for performing therapy energy threshold tests. The threshold tests allow the caregiver to determine the threshold energy at which paces capture the heart, i.e., cause a resulting contraction of the heart chamber to which the paces are delivered. The programmer provides recorded indications of the energy corresponding to each paced event, so that the caregiver can easily determine the point at which capture was lost. This recorded representation of pacing energy makes it easy for the caregiver to determine proper pacing thresholds to be used to ensure adequate pacing, while minimizing energy drain to prolong the useful life of the implanted device. | 10-21-2010 |
