Patent ID: 7530998

Claim:
A method of treating a diseased heart including the steps of: a. creating a hollow plastic sac with two openings, said sac being soft and compliant so that it will fill easily with blood to a certain, predetermined volume, but when the sac has reached capacity, no further expansion is allowed; b. creating a volume compensating device shaped to surround a significant portion of said sac, said volume compensating device having a hollow interior enabling the device to expand and contract upon the increase or decrease of fluid inside said hollow interior; c. creating an access tube joined to said volume compensating device in continuity with said hollow interior; d. inserting said device in the ventricle of the heart; e. inserting the said sac inside said device; f. connecting one of said openings in said sac to the annulus of the inflow valve of the ventricle; g. connecting the other of said openings in said sac to the annulus of the outflow valve of the ventricle; h. placing a fluid inside said hollow interior; and i. periodically removing fluid from said hollow interior in an incremental, stepwise, manner to permanently decrease the size of said device.
