Claim:
A method of treating a patient's heart by partitioning a chamber of the patient's heart into functioning and non-functioning portions, comprising: a. providing a first partitioning component which has an expandable reinforced membrane having a pressure receiving face in an expanded, deployed configuration; b. providing a second partitioning component having a second partitioning component which has an expandable reinforced membrane having a pressure receiving face in an expanded deployed configuration; c. deploying the first partitioning component in a partially expanded configuration within the chamber of the patient's heart to form in part a primary productive portion of the patient's heart chamber; d. securing the periphery of the reinforced membrane of the first partitioning component to the patient's heart wall; e. deploying the second partitioning component in a partially expanded configuration within the chamber of the patient's heart to cover a region of the patient's heart wall which is not covered by the first partitioning component to form in part the primary productive portion of the patient's heart chamber; f. securing the periphery of the reinforced membrane of the second partitioning component to the patient's heart wall.
