Unilateral diaphragmatic pacer
First Claim
1. An apparatus to innervate a deinnervated lung diaphragm and pace the deinnervated diaphragm with a normal innervated lung diaphragm, comprising:
- a sensing device adapted to be located to produce a signal representative of a change resulting from normal operation of the innervated diaphragm;
means to modify the signal in accordance with a predetermined pattern to provide a modified signal representative of the rate and duration of inspiration for the normal innervated lung diaphragm;
pulse generator means fed by the modified signal to produce a pulse; and
stimulating means adapted to innervate the deinnervated diaphragm at the same rate and duration as the normal innervated lung diaphragm in response to the pulse.

Abstract
An apparatus to innervate a deinnervated lung diaphragm and pace the deinnervated diaphragm with a normal innervated lung diaphragm. The apparatus has a sensing device sense operation of normal innervated lung diaphragm. The device produces a signal representative of the operation of the normal innervated diaphragm. The signal is modified in accordance with a set pattern to provide a modified signal showing the rate and duration of inspiration for the normal, innervated diaphragm. A pulse generator is fed by the modified signal to produce a pulse. A stimulator innervates the deinnervated diaphragm at the same rate and duration as a normal innervated lung diaphragm. A method of operating the apparatus is also described.

7. A method of operating an apparatus to innervate a deinnervated lung diaphragm and pace the deinnervated diaphragm with a normal innervated lung diaphragm, comprising the steps of
sensing a function of the normal innervated lung diaphragm and producing a signal representative of that function; -
modifying the signal in accordance with a predetermined pattern to provide a modified signal representative of the rate and duration of inspiration for the normal innervated lung diaphragm; utilizing the modified signal with a pulse generator means to provide a pulse; and feeding the pulse to stimulating means to innervate synchronously the deinnervated diaphragm at the same rate and duration as the normal innervated lung diaphragm. - View Dependent Claims (8, 9, 10, 11, 12)
