    摘要： A blood pump assembly has a balloon disposed at a distal region and a driveline disposed at a proximal region and is capable of being employed to provide mechanical circulatory support (e.g., counterpulsation). A blood pump support apparatus has a support structure with a head region and a tail region that is removably disposable in the blood pump assembly. When the support structure is disposed in the blood pump assembly, the head region is disposed within the balloon. When the blood pump assembly is implanted in the descending aorta and the support structure is disposed in the blood pump assembly, forces act on the balloon that would cause the balloon to roll or fold upon itself along an angle with respect to the balloon's longitudinal axis. The head region of support structure opposes these forces.

    摘要： The present disclosure is directed towards systems and methods built for predictively timing the inflation and/or deflation of an intra-aortic balloon pump. A controller operates in three states: (1) initialization state, (2) learning state, and (3) peak detection state. The controller decomposes a patient's electrocardiogram signal to a power signal. It then learns characteristics of the patient's electrocardiogram signal during the learning state and computes adaptive threshold parameter values. During the peak detection state, the controller applies the learnt threshold parameter values on a current electrocardiogram signal to identify occurrence and timings of R peaks in the electrocardiogram signal. The R-to-R peak timings are then used to trigger inflation of an intra-aortic balloon pump.

    摘要： A blood pump assembly comprises a balloon defining an elongated inflatable chamber with an opening at the proximal end. The proximal region of the balloon is substantially cylindro-conically shaped, and tapering toward the proximal end of the balloon, the central region of the balloon is substantially cylindrically shaped with a substantially uniform exterior diameter. The distal region of the balloon is substantially cylindro-conically shaped, the distal region of the balloon tapering toward the distal end of the balloon. The length of the distal region of the balloon is greater than approximately 15% of the combined length of the proximal and central regions of the balloon. A driveline may be coupleable to the opening and have a connection element disposed at a proximal end of the driveline. A radio opaque marker may be integrated into the driveline at a distal end of the driveline.

    摘要： A drive unit for intravascular circulatory support systems may include a motor, a ball nut, a ball screw, and a bellows. The motor may include a rotor and a stator. The ball nut may be affixed to the rotor. The bellows may have a first end and an second end and a bellows cavity located there between. The first end may be in fixed position and the second end may be defined by a dynamic flange having a recess carried by the bellows cavity. In turn, the recess of the dynamic flange may carry at least a portion of the motor. The second end may also receive the ball screw. Rotation of the rotor causes linear motion of the ball screw within the ball nut to actuate the bellows.
