Device and method to for independently stimulating hemidiaphragms
First Claim
Patent Images
1. An electrical stimulation device for increasing functional residual capacity of a subject comprising:
- an electrical stimulator comprising;
a first stimulation lead configured to electrically stimulate a first hemidiaphragm of a diaphragm; and
a second stimulation lead configured to electrically stimulate a second hemidiaphragm of a diaphragm,wherein each of said first stimulation lead and said second stimulation lead are independently controllable by the electrical stimulator, wherein the electrical stimulator is configured to provide stimulation to elicit a contraction of at least a portion of at least one of the first hemidiaphragm and the second hemidiaphragm to increase functional residual capacity.

Abstract
A device and method for treating a subject is provided where electrical stimulation may be separately provided to each hemidiaphragm to cause diaphragm contraction. Fatigue may be avoided among other possible benefits. Each hemidiaphragm may also be stimulated with different stimulation parameters. Stimulation may be smoothly transitioned between hemidiaphragms. Such stimulation may provide an increase in functional residual capacity or other therapeutic effects.
