What changed
USPTO has issued Patent US12594414B2 for a heart support apparatus to Imam Abdulrahman Bin Faisal University. The invention comprises a heart wrap with four inflatable compartments designed to cover the atriums and ventricles, an electrical stimulation system with negative and positive charge pads connected via lead cables to a power source, external piston pump devices for fluid circulation, suction tubes for fluid removal, and a programmable controller. The patent covers 20 claims including the multi-compartment structure, electrical stimulation methodology, and integrated fluid management system.
For medical device manufacturers and healthcare technology developers, this patent establishes intellectual property protection around cardiac support technology combining mechanical compression with electrical stimulation. Universities and research institutions developing similar cardiac assist technologies should conduct freedom-to-operate analyses to avoid potential infringement. The patent's broad claim scope covering both the mechanical and electrical aspects of heart support systems may limit competitive development in this specific technical approach.

Abstract
A heart support apparatus includes a heart wrap having a shape configured to conform with a heart of a patient. The heart wrap includes four inflatable compartments, each inflatable compartment is configured to cover one of a pair of atriums and a pair of ventricles. The apparatus includes a negative charge pad configured to deliver an electrical stimulus to the heart and a positive charge pad configured to receive the electrical stimulus. The negative and the positive charge pads are connected to a power source through negative and positive lead cables, respectively. An external device with four piston pumps is used to circulate fluids to the inflatable compartments. A first suction tube and a second suction tube remove a first fluid and a second fluid, respectively, from the heart wrap. A controller with program instructions controls the piston pumps.
