Interface devices for instruments in communication with implantable medical devices
First Claim
1. In an external medical instrument in physical contact with a patient'"'"'s body to communicate with or test the function of implantable medical devices (IMDs) implanted in the patient'"'"'s body or to measure a physiologic condition of the patient'"'"'s body and capable of communicating with other medical instruments or systems located at a distance from the patient, a safety system for protecting the patient from harm due to hazardous electrical signals comprising:
- an expansion bay of the external medical instrument adapted to receive a module expanding the capabilities of the external medical instrument, the docking bay further comprising an expansion bay interface connector;
a module fitted into the expansion bay and connected with the expansion bay interface connector having a module operating system;
a cable coupling the module operating system with the patient'"'"'s body for conducting electrical signals to and from the patient'"'"'s body;
an instrument operating system that creates and transmits module control data through the expansion bay interface connector in a transmission data path to the module operating system and receives module test data through the expansion bay interface connector in a reception data path from the module operating system; and
an opto-isolator within the module and in the transmission data path and the reception data path for isolating the instrument operating system from the module operating system to block passage of hazardous electrical signals through the cable to the patient'"'"'s body.

Abstract
External medical instruments that are in physical contact with a patient'"'"'s body to communicate with or test the function of implantable medical devices (IMDs) implanted in the patient'"'"'s body or to measure a physiologic condition of the patient'"'"'s body and capable of communicating with other medical instruments or systems located at a distance from the patient, and, particularly, safety systems for protecting the patient from harm due to hazardous electrical signals or potentials. The external medical instrument operates pursuant to an instrument operating system that processes and generates electrical signals. A patient cable is coupled to a patient'"'"'s body for transmitting electrical signals from the instrument operating system to the patient'"'"'s body and for receiving electrical signals from the patient'"'"'s body. A data cable extends to a remote instrument or a network, e.g., through a modem and Internet network connection, for communicating signals between the instrument operating system and the remote instrument or network. A first electrical isolation circuit between the instrument operating system and the data cable blocks conduction of hazardous electrical signals imposed upon the data cable from being conducted through the instrument operating system to the patient cable. A further electrical isolation circuit between the patient cable and the instrument operating system blocks conduction to the patient cable of hazardous signals conducted from the data cable through the instrument operating system.
