Remote physiological monitor
A system comprising a remotely programmable micromonitor with a wireless sensing system-on-module (SOM), one or more sensors to detect one or more conditions in a subject by monitoring one or more parameters associated with the conditions by comparing any monitored parameter to a baseline measurement of the monitored parameter from the subject, a plurality of sensors corresponding to a monitored parameter and connected to the micromonitor to convey measurements of all monitored parameters, the sensors including at least one of a non-optical pulse wave sensor or an electrocardiogram (ECG) sensor, a communications module capable of communicating with a wireless technology, wherein the module can send an alert signal to the subject or an attending physician or a remote service center or any other subject, and one or more algorithms for monitoring conditions and/or for predicting conditions, including at least one of a fall detection or fall prediction algorithm.
Systems and methods for alerting auditory prosthesis recipient
An alert system detects when an auditory prosthesis recipient is wearing her sound processor. When the processor is not worn, the alert system signals a secondary device, such as an accessory, to provide some other form of tactile stimulation to allow the recipient to be made aware of certain auditory stimuli she is not receiving via the auditory prosthesis. Thus, the alert system can effectively “hear” for the recipient. Since many auditory prosthesis recipients are, for all practical purposes, completely deaf without their external sound processors attached and operational, such an alert system increases the recipient's safety, convenience, and quality of life.
Mode of operation for an implantable cardiac rhythm management device co-implanted with a ventricular assist device
An implantable cardiac rhythm management medical device is configured to switch from a first operating mode to a second, ventricular assist device operating mode for detecting cardiac arrhythmias and controlling delivery of anti-arrhythmia therapy during the ventricular assist device operating mode. The implantable medical device may receive a command from another medical device indicating co-implantation of a ventricular assist device with the implantable medical device in a patient and switch from the first mode of operating to the second mode of operating in response to receiving the command. Switching from the first mode to the second mode may include adjusting at least one control parameter used for controlling an electrical stimulation therapy deliverable by the implantable cardiac rhythm management medical device.
Managing communication interference in leadless dual-chamber pacing systems and other IMD systems
Embodiments described herein relate to implantable medical devices (IMDs) and methods for use therewith. Such a method includes enabling a communication capability of an IMD during a message alert period and monitoring for a message while the communication capability is enabled during the message alert period. In response to receiving a message during the message alert period, there is a determination whether the message is valid or invalid. If the message is invalid, the message is ignored, and an invalid message count is incremented. A further message is monitored for during the message alert period occurs, when the invalid message count has not yet reached a corresponding invalid message count threshold. The communication capability of the IMD is disabled for a disable period, when the invalid message count reaches the corresponding invalid message count threshold. If a valid message is received, the IMD acts upon information included therein.
Methods for operating a system for management of implantable medical devices and related systems
In one embodiment, a method for operating a system for management of implantable medical devices (IMDs), comprises: conducting communication sessions with a plurality of clinician programmer devices while the clinician programmer devices are engaged in respective programming sessions with IMDs; receiving and storing second programming data from a plurality of clinician programmer devices, wherein the second programming data was created during programming sessions with IMDs without network connectivity to the system for management of IMDs; reconciling programming of the plurality of IMDs that were programmed with the second programming data with data stored by the system for management of IMDs; and communicating second signed validation data to cause IMDs to conduct therapeutic operations according to programming data validated by respective instances of second validation data.
LEADLESS PACEMAKER SYSTEMS, DEVICES AND METHODS THAT MONITOR FOR ATRIAL CAPTURE
Systems, devices, and methods for monitoring for atrial capture are disclosed. Such a method, for use within an implantable system including an atrial leadless pacemaker (aLP) and a ventricular leadless pacemaker (vLP), includes storing within a memory of the vLP a paced atrial activation morphology template corresponding to far-field atrial signal components expected to be present in a vEGM sensed by the vLP when an atrial pacing pulse delivered by the aLP captures atrial tissue. The vLP senses a vEGM and compares a morphology of a portion of the sensed vEGM to the paced atrial activation morphology template to determine whether a match therebetween is detected. Additionally, the vLP determines whether atrial capture occurred or failed to occur (responsive to an atrial pacing pulse), based on whether the vLP detects a match between the morphology of a portion of the sensed vEGM and the paced atrial activation morphology template.
IMPLANTABLE MEDICAL DEVICE USING TEMPERATURE SENSOR TO DETERMINE INFECTION STATUS OF PATIENT
Techniques for detecting infections in a patient in relation to temperature values obtained from implantable temperature sensors are described. An example implantable temperature sensor may be included within a housing of an implantable medical device (IMD). In some examples, the temperature sensor may determine a plurality of temperature values over time. Processing circuitry of the IMD or of an external device may smooth the temperature values and apply an infection detection model to the smoothened temperature signal to determine an infection status of the patient.
Implantable medical device using permanent and temporary keys for therapeutic settings and related methods of operation
In one embodiment, an implantable medical device (IMD) comprises: therapeutic circuitry for controlling delivery of a medical therapy to a patient; a processor for controlling the IMD according to executable code; wireless communication circuitry for conducting wireless communications; and memory for storing data and executable code, wherein the executable comprises code for causing the processor to (1) communicate with an external programming device to define therapeutic settings for operation of the IMD, (2) perform validation operations on one or more instances of therapeutic settings by determining whether a respective instance of therapeutic settings is accompanied by permanent validation data or temporary validation data, wherein the validation operations comprise analyzing temporary validation data against at least one key of a plurality of cryptographic keys stored by the IMD.
METHOD FOR INCLUDING REDUNDANCY IN COMMUNICATING AN ALERT CONDITION FROM AN IMPLANTED SYSTEM TO AN EXTERNAL SYSTEM
A method, implantable medical system and an external system for communicating an alert signal via a transcutaneous energy transfer system (TETS), with or without the presence of transmission of the alert signal by an alternative wireless communication system, are disclosed. According to one aspect, a method in an implanted medical system includes obtaining the alert signal based on an occurrence of an event, and transmitting the alert signal from the implanted medical device to the external system via a TETS used to transfer power requests to the external system.
ASYSTOLE DETECTION AND RESPONSE IN AN IMPLANTABLE CARDIOVERTER DEFIBRILLATOR
An implantable cardioverter defibrillator (ICD) receives a cardiac electrical signal by a sensing circuit while operating in a sensing without pacing mode and detects asystole based on the cardiac electrical signal. The ICD determines, in response to detecting the asystole, if asystole backup pacing is enabled, and automatically switches to a temporary pacing mode in response to the asystole backup pacing being enabled. Other examples of detecting asystole and providing a response to detecting asystole by the ICD are described herein.
