  • Patent number: 11007370
    Abstract: A method is provided for establishing a communication session with an implantable medical device (“IMD”). The method includes configuring an IMD and an external device to communicate with one another through a protocol that utilizes a dedicated advertisement channel. The advertisement period and the scan period of the protocol are independent of one another such that the advertisement and scan periods at least partially overlap intermittently after a number of cycles. When the external device detects one of the advertisement notices, the method includes establishing a communications link between the external device and the IMD.

A received message and/or a channel over which messages can be received is/are examined, and a value is adjusted based on results thereof. After being adjusted, the value is compared to a first threshold if the IMD is in a normal state, or compared to a second threshold if the IMD is in a noise state. If in the normal state, there is a determination whether to stay in the normal state or switch to the noise state. If in the noise state, there is a determination whether to stay in the noise state or switch to the normal state. At least the second receiver is temporarily put to sleep, if the IMD is maintained in or switched to the noise state.

  • Patent number: 10819713
    Abstract: An implantable medical device (IMD) includes communication circuitry that enables the IMD to communicate via a network such as the Internet. A security routine is executed on the IMD to determine whether the IMD is capable over communicating via the network. If so, the IMD requests an identifier of current firmware stored on a server that is connected to the communication network. The identifier of the current firmware is compared to an identifier of firmware that is installed on the IMD. If the installed firmware is the same as the current firmware on the server, a timer is reset, but if the installed firmware cannot be verified as matching the current firmware on the server (e.g., because the IMD is not capable of communicating via the network), the timer continues to run. When the timer expires, the IMD is prevented from communicating via the network until further action is taken.

  • Patent number: 10799704
    Abstract: A proximity-based security mechanism can control access to the programming interface of an implanted medical device. The security mechanism prevents unauthorized remote access to the programming interface by hackers or other hostile individuals, securing the safety of the subject. The system also allows the subject or other responsible person to activate the programming interface when changes to the operation of the implanted medical device are needed. In one example, a security interface is operable to detect, while implanted in the subject, an activation signal produced in close proximity to the subject, and activate the programming interface in response to the activation signal so that the implantable medical device can receive the programming instructions. A proximity-based security mechanism can be a dedicated device, or can be implemented in a programmable computing device such as a smartphone or other mobile computing device.

  • Patent number: 10786208
    Abstract: Systems and methods for predicting and/or detecting cardiac events based on real-time biomedical signals are discussed herein. In various embodiments, a machine learning algorithm may be utilized to predict and/or detect one or more medical conditions based on obtained biomedical signals. For example, the systems and methods described herein may utilize ECG signals to predict and detect cardiac events. In various embodiments, patterns identified within a signal may be assigned letters (i.e., encoded as distributions of letters). Based on the known morphology of a signal, states within the signal may be identified based on the distribution of letters in the signal. When applied in the in-vehicle environment, drivers or passengers within the vehicle may be alerted when an individual within the vehicle is, or is about to, experience a cardiac event.

  • Patent number: 10780276
    Abstract: Systems and methods for selecting low-power, effective signal delivery parameters for an implanted pulse generator are disclosed. A representative system includes a signal generator and a computer-readable medium that, for first and second signals, increases and decreases an amplitude of the signal over multiple steps from a baseline amplitude at which the patient has a baseline response. At individual step increases and decreases, the system receives a pain score based on the patient's response. The instructions compare the pain scores for the two signals and determine one of the signals for additional therapy to the patient, based on the pain scores and an expected energy consumption of the signals.

  • Patent number: 10768139
    Abstract: An electrochemical probe comprises a wire bundle including two or more wire electrodes made of conducting material arranged alongside each other, and insulating material surrounding the electrodes. An impedance reducing layer of metal or metal oxide nano-structures is deposited on tips of the wire electrodes at a first end of the bundle. A functionalization layer is deposited on the impedance reducing layer at the first end of the bundle. Such a probe is particularly useful for electrochemical sensing applications such as neuronal scanning.

  • Patent number: 10758731
    Abstract: An external device transfers a key to an implantable medical device over a proximity communication and then establishes a first far field communication session with the implantable medical device where the key is used for the first communication session. This first communication session may occur before implantation while the implantable medical device is positioned outside of the sterile field so that using a proximity communication is easily achieved. Once the implantable medical device is passed into the sterile field for implantation, the external device may then establish a second far field communication session with the implantable medical device where the last key that was used for the first communication session is again used for the second communication session which avoids the need for another proximity communication to occur within the sterile field.

  • Patent number: 10743779
    Abstract: A system and method for controlling a monitoring mode or treatment mode of an implantable medical device based on the detection of an external signal. The system and related method allow for more frequent monitoring of medical parameters at times where more frequent monitoring is necessary, such as during or after a dialysis session, with less frequent monitoring at other times, allowing for a more efficient medical device. The invention also allows for the frequency or mode of treatment by the implantable medical device, or the transmission of data from the implantable medical device to be controlled based on the external signal.
