Abstract
An implantable medical device comprises a functional device for carrying out a therapeutic or diagnostic function, and a communication device for communicating with a remote monitoring system. The communication device, at a start of initial operation of the implantable medical device, is enabled to establish a communication with said remote monitoring system. In this way an implantable medical device is provided which allows for including the implantable medical device in a remote monitoring while reducing a risk for a patient involved with attending to the patient for activating a remote monitoring function within the implantable medical device.
Core Innovation
The invention relates to an implantable medical device that includes a functional device for carrying out a therapeutic or diagnostic function and a communication device for communicating with a remote monitoring system. At a start of initial operation of the implantable medical device, the communication device is enabled to establish a communication with the remote monitoring system.
The communication device repeatedly transmits a transmit signal according to a predefined first time scheme, including transmitting at a regular first time interval. The transmit signal is configured to trigger the remote monitoring system to establish a communication connection to the implantable medical device, and the repeated transmission requires a current consumption of less than 20 mAs per day.
Upon establishment of a communication connection, the implantable medical device initiates at least one communication function. The implantable medical device activates the at least one communication function only if a specific activation criterion is fulfilled, where the activation criterion is that in a pre-defined previous time span a specified number of successful communication connections have been established between the implantable medical device and the remote monitoring system.
Claims Coverage
The document provides two independent claims. Both claims share the same main inventive concept: initial automatic enabling of communication with a remote monitoring system via repeated trigger-signal transmissions using a predefined first time scheme, combined with a power/current constraint and conditional activation of communication functions based on prior successful connections within a predefined previous time span.
Repeated transmission of a trigger signal according to a predefined first time scheme at start of initial operation
The communication device, at a start of initial operation of the implantable medical device, is enabled to establish a communication with the remote monitoring system and is configured to transmit a transmit signal repeatedly according to a predefined first time scheme to establish a communication with said remote monitoring system.
Triggering remote-side connection establishment via transmit signal
The transmit signal is configured to trigger the remote monitoring system to establish a communication connection to the implantable medical device.
Power/current consumption constraint for repeated transmission
The repeated transmission of the transmit signal requires a current consumption of less than 20 mAs per day.
Initiating communication functions on connection establishment with conditional activation criterion
The implantable medical device is configured to initiate at least one communication function on the occasion of establishment of a communication connection with the remote monitoring system, and to activate the at least one communication function only if a specific activation criterion is fulfilled, the activation criterion being that in a pre-defined previous time span a specified number of successful communication connections have been established between the implantable medical device and the remote monitoring system.
Across both independent claims, communication is initially enabled at the start of initial operation by repeatedly transmitting a transmit signal according to a predefined first time scheme to trigger the remote monitoring system to establish a connection, while keeping the repeated transmission power-limited to less than 20 mAs per day. Communication functions are initiated when the connection is established and are activated only when the activation criterion based on successful connections in a predefined previous time span is fulfilled.
Stated Advantages
Reduced patient risk and logistical burden, including avoiding a programming visit during pandemics.
Documented Applications
Remote monitoring of an implantable medical device via communication with a remote monitoring system.
