Abstract

Systems and methods are provided for updating medical devices. An exemplary system includes a medical device and a remote device. The medical device is operable to regulate a condition of a user. The remote device receives measurement data correlative to the condition of the user, determines control information for the medical device based at least in part on the measurement data, and transmits the control information via a first peer-to-peer communication session. The medical device receives the control information via a second peer-to-peer communication session and thereafter regulates the condition of the user based at least in part on the control information and subsequent measurement data.

First claim

What is claimed is:

1. A system comprising:
a medical device to regulate a condition of a user and maintain first network identification information for an intermediate device paired with the medical device over a first communications network; and
a remote device to establish an association between the medical device and the intermediate device, maintain second network identification information for the intermediate device on a second communications network, receive measurement data correlative to the condition of the user, determine updated control information for the medical device based at least in part on the measurement data, autonomously initiate establishment of a first peer-to-peer communication session with the intermediate device over the second communications network by transmitting a connection request to the intermediate device via the second communications network, and automatically transmit the updated control information to the intermediate device via the first peer-to-peer communication session in response to receiving an acknowledgment from the intermediate device in response to establishing a second peer-to-peer communication session with the medical device over the first communications network, wherein:
the medical device receives the updated control information via the second peer-to-peer communication session with the intermediate device over the first communications network and thereafter autonomously regulates the condition of the user based at least in part on the updated control information and subsequent measurement data; and
the first communications network and the second communications network are distinct.

2. The system of claim 1 , wherein:
the medical device transmits the measurement data to the intermediate device via a third peer-to-peer communication session; and
the intermediate device transmits the measurement data to the remote device via a fourth peer-to-peer communication session.

3. The system of claim 2 , wherein:
the medical device initiates the third peer-to-peer communication session with the intermediate device over the first communications network;
the intermediate device establishes the fourth peer-to-peer communication session with the remote device over the second communications network; and
the medical device transmits the measurement data via the third peer-to-peer communication session in response to the intermediate device establishing the fourth peer-to-peer communication session with the remote device.

4. The system of claim 1 , wherein:
the updated control information includes a target value for the condition of the user and one or more control parameters;
the subsequent measurement data comprises one or more measured values correlative to the condition of the user; and
the medical device regulates the condition of the user based on the one or more control parameters and a difference between the target value and the one or more measured values.

5. The system of claim 1 , wherein:
the medical device establishes a third peer-to-peer communication session on the first communications network and transmits the measurement data via the third peer-to-peer communication session;
the remote device receives the measurement data via a fourth peer-to-peer communication session on the second communications network; and
after determining the updated control information:
the remote device establishes the first peer-to-peer communication session on the second communications network; and
the medical device receives the updated control information via the second peer-to-peer communication session on the first communications network.

6. The system of claim 1 , wherein:
the medical device uploads the measurement data and delivery data characterizing delivery of a fluid to the user, the fluid influencing the condition of the user; and
the remote device determines the updated control information based at least in part on the measurement data and the delivery data.

7. The system of claim 1 , wherein the medical device comprises an infusion device including:
a motor operable to deliver fluid to the user, the fluid influencing the condition of the user;
one or more data storage elements to maintain the updated control information and the first network identification information; and
a control module coupled to the motor and the one or more data storage elements to operate the motor based on the updated control information and the subsequent measurement data to regulate the condition of the user.

8. The system of claim 1 , wherein:
the remote device initiates the first peer-to-peer communication session with the intermediate device over the second communications network;
the intermediate device establishes the second peer-to-peer communication session with the medical device over the first communications network in response to the remote device initiating the first peer-to-peer communication session; and
the remote device transmits the updated control information in response to the intermediate device establishing the second peer-to-peer communication session with the medical device.

9. The system of claim 1 , wherein the intermediate device streams the updated control information from the remote device via the first peer-to-peer communication session to the medical device via the second peer-to-peer communication session.

10. A method of updating a medical device, the method comprising:
maintaining, at the medical device, first network identification information for an intermediate device paired with the medical device on a first communications network;
maintaining, at a remote device, second network identification information for the intermediate device on a second communications network, wherein the first communications network and the second communications network are distinct;
uploading measurement data from the medical device to a remote device, the measurement data comprising one or more measured values correlative to a condition of a user associated with the medical device;
determining, by the remote device based at least in part on the measurement data, updated control information for regulating the condition of the user;
autonomously initiating, by the remote device via the second communications network, a peer-to-peer communication session with the medical device over the first communications network via the intermediate device previously paired with the medical device by transmitting a connection request to the intermediate device via the second communications network;
receiving, by the remote device via the second communications network, an acknowledgment from the intermediate device in response to the intermediate device establishing the peer-to-peer communication session on the first communications network; and
in response to the acknowledgement, automatically transmitting, by the remote device, the updated control information to the intermediate device via the second communications network, wherein the intermediate device provides the updated control information to the medical device via the peer-to-peer communication session.

11. The method of claim 10 , wherein:
initiating the peer-to-peer communication session comprises initiating, by the remote device, a first peer-to-peer communication session with the intermediate device over the second communications network, the intermediate device establishing a second peer-to-peer communication session with the medical device over the first communications network; and
providing the updated control information comprises the remote device transmitting the updated control information to the intermediate device via the first peer-to-peer communication session over the
