Abstract
A pacemaker or similar cardiac and cardiomyoplasty muscle stimulator is provided which during a training period of said muscle, defining alternating training and augmentation phases. During training phases training pulses are provided for the muscle until the muscle is capable of performing cardiac assistance for relatively extended time periods. During the augmentation phases, augmentation pulses are applied to the muscle to provide cardiac assistance even with a muscle with no, or limited training.
Claims7
An cardiomyoplasty control device for controlling an implanted muscle arranged and constructed to provide cardiac assistance, said control device comprising:
- electrode means for delivering stimulation pulses to said muscle;
- and
- timing means for controlling the timing of said stimulation pulses, said timing means defining a sequence of training periods, each training period including augmentation phases interlaced with training phases, wherein in said training phases said stimulation pulses are applied at a first interval selected to train said muscle;
- and wherein in said augmentation periods, said stimulation pulses are applied at a second interval selected to augment the cardiac function.
An implantable pacemaker for providing pulses to a patient's heart and to a muscle arranged to assist said heart, said pacemaker comprising:
- cardiac pulsing means for generating cardiac pulses for said heart;
- muscle pulsing means for generating muscle pulses for said muscle;
- and
- control means for controlling said cardiac and muscle pulsing means, said control means including timing means for defining a sequence of training periods consisting of training phases during which training pulses are selectively generated to train said muscle, and augmentation phases interspace with said training phases, wherein during said augmentation phases augmentation pulses are generated for said muscle for augmenting the cardiac function.
