Abstract
Abstract A system for administering medical therapy includes an implantable medical apparatus containing an audio transmitter and an audio receiver for respectively transmitting and receiving extracorporeally audible audio signals. The system also includes an extracorporeal programming and control apparatus, which also includes an audio transmitter and an audio receiver. The medical apparatus can thus communicate directly, in both directions, with the extracorporeal programming and control apparatus by means of audio signals. Such communication can take place, for example, via a telephone line, so that the patient in whom the medical apparatus is implanted need not be physically present at the location of the extracorporeal programming and control apparatus in order to establish communication.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
247 words
A medical therapy system comprising: an implantable medical apparatus for administering therapy to a patient, said implantable medical apparatus including audio transmitter means for transmitting extracorporeally audible audio signals having a frequency in a range of 250 to 8,000 Hz, programmable control means for operating according to a program employing data for controlling administration of therapy to said patient and for supplying a first signal to said audio transmitter means containing information relating to said data for transmission by said audio transmitter means in said audible audio signals, and an audio receiver means connected to said control means for directly receiving extracorporeally generated audio signals also having a frequency in said range for operating said control means; and an extracorporeal programming and control apparatus including audio receiver means for receiving said audio signals from said audio transmitter means of said implantable medical apparatus, audio transmitter means for generating said extracorporeally generated audio signals receivable by said audio receiver means in said implantable medical apparatus, and control means for generating a second signal containing programming instructions and data for use by said implantable medical apparatus said audio transmitter means and said audio receiver means of said implantable medical apparatus and said audio transmitter means and said audio receiver means of said extracorporeal programming and control apparatus forming, in combination means for audibly transmitting data, in said frequency and programming instructions between said control means in said implantable medical apparatus and said control means extracorporeal programming and control apparatus.
Claim 2
Dependent Claim
247 words
A medical therapy system comprising: an implantable medical apparatus for administering therapy to a patient, said implantable medical apparatus including audio transmitter means for transmitting extracorporeally audible audio signals having a frequency in a range of 250 to 8,000 Hz, programmable control means for operating according to a program employing data for controlling administration of therapy to said patient and for supplying a first signal to said audio transmitter means containing information relating to said data for transmission by said audio transmitter means in said audible audio signals, and an audio receiver means connected to said control means for directly receiving extracorporeally generated audio signals also having a frequency in said range for operating said control means; and an extracorporeal programming and control apparatus including audio receiver means for receiving said audio signals from said audio transmitter means of said implantable medical apparatus, audio transmitter means for generating said extracorporeally generated audio signals receivable by said audio receiver means in said implantable medical apparatus, and control means for generating a second signal containing programming instructions and data for use by said implantable medical apparatus said audio transmitter means and said audio receiver means of said implantable medical apparatus and said audio transmitter means and said audio receiver means of said extracorporeal programming and control apparatus forming, in combination means for audibly transmitting data, in said frequency and programming instructions between said control means in said implantable medical apparatus and said control means extracorporeal programming and control apparatus.
Claim 3
Dependent Claim
28 words
A system as claimed in claim 1 wherein said audio transmitter means and said audio receiver means of said implantable medical apparatus comprise, in combination, an audio transceiver.
Claim 4
Dependent Claim
77 words
A system as claimed in claim 1 wherein said control means of said implantable medical apparatus includes a magnetically actuated switch, wherein said system comprises means for temporarily causing said switch to be disposed in a magnetic field which actuates said switch, and wherein said control means comprises means for enabling transmission of said first signal from said control means to said audio transmitter means in said implantable medical apparatus in the presence of said magnetic field.
Claim 5
Dependent Claim
108 words
A system as claimed in claim 1 wherein said implantable medical apparatus includes signal modulator means for modulating said first signal to form said audible audio signals transmitted by said audio transmitter means and a signal demodulator means for demodulating signals received by said audio receiver means in said implantable medical apparatus, and wherein said extracorporeal programming and control apparatus includes means for modulating said second signal to form said audible audio signals transmitted by said audio transmitter means in said extracorporeal programming and control apparatus and signal demodulator means for demodulating said audio signals received by said audio receiver means in said extracorporeal programming and control apparatus.
Claim 6
Dependent Claim
70 words
A system as claimed in claim 4 wherein said signal modulator means in said implantable medical apparatus and in said extracorporeal programming and control apparatus respectively comprise means for frequency-modulating said first and second signals to form frequency-modulated audible audio signals, and wherein said signal demodulator means in each of said implantable medical apparatus and said extracorporeal programming and control apparatus comprises means for demodulating said frequency-modulated audible audio signals.
Claim 7
Dependent Claim
70 words
A system as claimed in claim 4 wherein said signal modulator means in said implantable medical apparatus and in said extracorporeal programming and control apparatus respectively comprise means for pulsecode-modulating said first and second signals to form pulsecode-modulated audible audio signals, and wherein said signal demodulator means in each of said implantable medical apparatus and said extracorporeal programming and control apparatus comprises means for demodulating said pulsecode-modulated audible audio signals.
