摘要： A minimally invasive circulatory support platform that utilizes an aortic stent pump or pumps. The platform uses a low profile catheter-based techniques and provides temporary and chronic circulatory support depending on the needs of the patient. Also described is a catheter-based temporary assist pump to treat patients with acute decompensated heart failure and provide circulatory support to subjects undergoing high risk percutaneous coronary intervention (“PCI”). Further described is a wirelessly powered circulatory assist pump for providing chronic circulatory support for heart failure patients. The platform and system are relatively easy to place, have higher flow rates than existing systems, and provide improvements in the patient's renal function.

摘要： A minimally invasive system for a wireless circulatory support pump that utilizes a low profile catheter-based techniques and provides temporary and chronic circulatory support depending on the needs of the subject. The system includes a wireless circulatory assist pump, a deployment catheter, and a retrieval catheter for inserting and removing the wireless circulatory assist pump from a subject. The wireless circulatory support pump is relatively easy to place, has high flow rates, and provide improvements in the subject's renal function.

摘要： A minimally invasive circulatory support device, system, and related methods. The circulatory assist devices, systems, and methods use low profile catheter-based techniques and provide temporary and chronic circulatory support depending on the needs of the patient. The circulatory assist device, systems, and methods include a stent cage and an impeller. The stent cage is formed of a first material that is sufficiently rigid to expand radially outward and press against an artery wall is sufficiently deformable to collapse within the outer sheath. The impeller includes at least one blade formed of a second material that is sufficiently rigid to expand and retain shape while rotating and assisting blood to flow within the artery and is sufficiently deformable to collapse within the outer sheath with the stent cage.

摘要： A minimally invasive circulatory support platform that utilizes an aortic stent pump or pumps. The platform uses a low profile catheter-based techniques and provides temporary and chronic circulatory support depending on the needs of the patient. Further described is a wirelessly powered circulatory assist pump for providing chronic circulatory support to, for example, heart failure patients. The platform and system are relatively easy to place, have higher flow rates than existing systems, and provide improvements in the patient's renal function.

摘要： A coupling for a circulatory assist device includes a first coupler and a second coupler. The first coupler including a first inner portion configured to be secured to a first shaft, a first body extending from the inner portion, and first magnets joined to the body. The second coupler offset from and separate from the first coupler with a gap therebetween. The second coupler including a second inner portion configured to be secured to a second shaft, a second body extending from the second inner portion, and second magnets joined to the body. The second magnets magnetically coupled to the first magnets and configured to transfer a torque applied to one of the first shaft and the second shaft to an other of the first shaft and the second shaft.
