| 20110245582 | Method and System for Closed Chest Blood Flow Support - A method of providing a pumping system for assisting a human patient's heart and providing a blood pump to be disposed outside the patient's body is disclosed. The blood pump has an inlet and an outlet. An inlet cannula is provided for insertion percutaneously into the vascular system of the patient, and is adapted to be placed in fluid communication with the blood pump inlet to provide blood to the blood pump. An outlet perfusion cannula is provided for insertion percutaneously into the vascular system of the patient, and is adapted to be placed in fluid communication with the blood pump outlet to provide blood to the patient's vascular system. The blood pump includes a control system to control the blood pump. The control system includes at least two control units for redundant control of the blood pump, and each control unit includes a watchdog for monitoring the control unit. | 10-06-2011 |
| 20110160518 | Method and System for Closed Chest Blood Flow Support - A system for assisting flow of blood by a patient's heart. The system includes a transseptal cannula adapted to be inserted percutaneously in the vascular system and extend through the atrial septum from the right atrium to the left atrium. The system includes a blood pump mechanism having a blood pump for pumping blood received from the transseptal cannula that has been oxygenated at specified flow rates over a range of physiological pressures. The blood pump is connected to the transseptal cannula. The system includes a perfusion cannula adapted to be inserted percutaneously in the vascular system for returning oxygenated blood to the atrial system of the patient. The perfusion cannula is connected to the blood pump. | 06-30-2011 |
