    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 cardiac assist device (1) with a cup element (2), an inner balloon element (5) and a tube element (6). The cup element (2) has a cup wall (2a), one or more in-flow openings (3), and an outflow element (4 having an aperture (4a). The inner balloon element (5) is positioned inside the cup element (2) free from the outflow element (4). The tube element (6) is arranged for inflating and deflating the inner balloon element (5) during operation. During operation in a pumping operational mode, the combination of first material, dimensions of the cup wall (2a), and dimensions of the outflow element (4) provides a containment force by the cup element (2) counteracting an outward directed force of the inner balloon element (5).

    摘要： A method for providing a treatment recommendation to a physician for treating a patient is disclosed. The method comprises determining, from a processor in communication with a patient data repository, a first treatment recommendation based on a combination of selected patient demographics from the patient data repository applicable to the patient, and operational parameters of a plurality of ventricular assist devices (VADs) suitable for treating the patient, the first treatment recommendation having a first survival rate and comprising the use of a first VAD. The method then obtains a first signal from using the first VAD on the patient. The method then determines a second treatment recommendation based on the first signal and the first treatment recommendation, the second treatment recommendation having a second survival rate. The method then provides the second treatment recommendation to the physician if the second survival rate is higher than the first survival rate.
