1. A method of providing collateral blood flow through a patient'"'"'s skeletal muscle to a patient'"'"'s myocardial tissue, comprising:

  • a) operatively connecting a skeletal muscle pedicle of the patient to said myocardial tissue, the muscle pedicle retaining its source of blood flow;

    b) attaching a stimulator to said skeletal muscle and delivering stimulus pulses from said stimulator to said skeletal muscle; and

    c) controlling said stimulator to deliver chronic stimulus pulses to said muscle in accordance with a chronic pattern so as to provide chronic collateral blood flow from said muscle to said myocardium, and changing the pattern of delivering stimulus pulses for acute periods during increased levels of patient cardiac demand, said controlling providing for increased collateral flow from said skeletal muscle to said myocardial tissue.
