20120041256 | APPARATUS FOR PROVIDING SHORT-TERM CARDIAC SUPPORT - An apparatus provides short-term cardiac support after cardiac surgery using a cardiopulmonary bypass (CPB) pump (or heart-lung machine) having a pump coupled to a pump controller for pumping oxygenated blood through a cannula into the patient The pump controller controls the pump in a first mode to generate pulsatile flow of the oxygenated blood to the patient, and in a second mode to provide counter-pulsatile flow of blood through the cannula synchronized with the heart of the patient, whereby, when the heart of the patient is in diastole, the pump forces blood from the cannula into the patient, and when the heart is in systole, the pump removes blood from the patient via the cannula. | 02-16-2012 |

20090114056 | ADJUSTABLE STEERING COLUMN ASSEMBLY - An adjustable steering column assembly including a column jacket moveable in at least one of a telescoping direction and a raking direction is disclosed. First and second gears are coupled to a rake bracket and mesh with each other with the first gear rotatable about a first pivot axis transverse to a longitudinal axis and the second gear rotatable about a second pivot axis transverse to the longitudinal axis and spaced above the first pivot axis such that rotation of the first gear causes rotation of the second gear. A cam mechanism is coupled to the rake bracket and to each of the first and second gears with the cam mechanism movable along the first and second pivot axes during rotation of the first and second gears for selectively engaging the rake bracket to prevent movement of the column jacket in at least one of the telescoping and raking directions. | 05-07-2009 |
