摘要： A blood pump system includes a first implantable housing, an implantable blood pump independent from the first implantable housing, and a percutaneous extension. The first implantable housing includes a rechargeable power storage device. The implantable blood pump supplements the pumping function of a heart. The rechargeable power storage device supplies electrical power to the implantable blood pump. The percutaneous extension is coupled to the rechargeable power storage device and adapted to traverse the skin. The percutaneous extension is configured to releasably connect to an external power supply adapted to provide power for recharging or supplementing the rechargeable power storage device to power the implantable blood pump.

摘要： A method of transferring electrical power to a medical device implanted in a patient includes supporting a prosthetic rib segment via a rib of the patient. A percutaneous electrical connector is supported via the prosthetic rib segment so as to expose a connection port of the electrical connector via a skin aperture through a skin portion of the patient. Electrical power is transferred to the medical device via an external power cable connected to the connection port and an implanted power cable connected with the percutaneous electrical connector.

摘要： An implantable system includes a ventricular assist device (VAD), a cuff for attachment to a heart, and a latching mechanism attached to the VAD. The VAD includes an inlet cannula. The cuff defines an outward facing circumferential groove and an opening for the inlet cannula. The cuff includes a plurality of ridges disposed at least partially within the outward facing circumferential groove. The latching mechanism is reconfigurable between an unlatched configuration in which the latching mechanism accommodates insertion of the inlet cannula into the opening and a latched configuration in which the latching mechanism is engaged with the cuff to restrain the position of the inlet cannula relative to the cuff and engaged with at least one of the plurality of ridges to block rotation of the VAD relative to the cuff.

摘要： Mechanical circulatory assist systems and related methods produce a pulsatile blood flow in synchronization with heart activity. A mechanical circulatory assist system includes a continuous-flow pump and a controller. The continuous-flow pump is implantable in fluid communication with a left ventricle of a heart of a patient and an aorta of the patient to assist blood flow from the left ventricle to the aorta. The controller includes a sensor that generates a signal indicative of an activity of the heart. The controller is operatively connected to the continuous-flow pump and configured to operate the continuous-flow pump in an artificial pulse mode in synchronization with the activity of the heart.

摘要： The invention generally relates to improved medical blood pump devices, systems, and methods. For example, blood pumps may be provided that include a housing defining a blood flow path between an inlet and an outlet. A rotor may be positioned in the blood flow path. A motor stator may be driven to rotate the rotor to provide the blood flow through the pump. Axial and/or tilt stabilization components may be provided to increase an axial and/or tilt stabilization of the rotor within the blood flow path. In some embodiments, biasing forces are provided that urge the rotor toward a bearing component. The biasing force may be provided by adjusting drive signals of the motor stator. Additionally, or alternatively, one or more magnets (e.g., permanent/stator magnets) may be provided to bias the rotor in the upstream and/or downstream direction (e.g., toward a bearing (chamfer, step, conical), or the like).

摘要： A mechanical circulatory assist system includes a continuous-flow pump and a controller. The pump is implantable to assist blood flow from the left ventricle to the aorta The controller is operable to control a rotation speed of the pump over an operational cycle. The operational cycle includes a first segment over which the ventricular assist device is operated at first rotation speed, a second segment over which the rotation speed of the ventricular assist device is decreased from the first rotation speed to a second rotation speed, a third segment over which the ventricular assist device is operated at the second rotation speed, and a fourth segment over which the rotation speed of the ventricular assist device is increased from the second rotation speed. A contraction of the left ventricle that opens and closes the native aortic valve occurs during the third segment.

摘要： In one general aspect, a cuff for attachment to a heart includes an attachment component configured to engage a blood pump to attach the cuff to the blood pump and a sewing ring for attachment to the heart. The sewing ring is coupled to the attachment component, and the attachment component and the sewing ring each define a central opening configured to admit an inflow cannula of a blood pump. The sewing ring comprises a member that provides rigidity to flatten a portion of a myocardium of the heart when the cuff is attached to the heart.

摘要： In order to produce a pulsatile blood flow pattern that includes time periods of relatively high blood flow rates and time periods of relatively low blood flow rates, the operating speed of a blood pump can be selectively controlled to produce an operating speed pattern that includes time periods of relatively high rotation speeds and periods of relatively low rotation speeds. For example, the blood pump is rotated at a first speed for a first period of time. The speed of the blood pump is then decreased from the first speed to a second speed and is operated at the second speed for a second amount of time. The speed of the blood pump is then decreased to a third speed for a third amount of time. If desired, the operating speed pattern can be repeated to continue the pulsatile blood flow pattern.
