ABSTRACT:
An implantable medical device having a main body, and a port in the main body for receiving a medical instrument percutaneously. A resilient dome is mounted in the device for communicating with the medical instrument, and for flexing from a first rest position to a second position after contact with the medical instrument. The dome provides an extra corporeal response signal resulting from the flexion of the dome from the first position to the second position.
