摘要： Defining proximal as toward the heart and distal as away from the heart, a sheath includes a proximal opening and multiple fenestrations maintainable in position slightly beyond a site or point of sheath entry into a vessel by way of an anchoring assembly having a set of radially displaceable anchoring elements configured for abutting a superficial vessel wall. The fenestrations and/or anchoring element(s) are arranged obliquely or non-obliquely around peripheral portions of the sheath. The sheath can receive blood from a pumping source at a proximal opening, and channel the blood toward, to, and through the fenestrations. The fenestrations, in combination with the proximal opening, enable the perfusion of blood into the cannulated vessel in a set of distal directions for perfusing a distal tissue or organ. Flow of blood out of fenestrations directs blood distally towards the limb, head, or other distal region, mitigating the risk of or preventing ischemia.

摘要： An aspiration system includes a plurality of catheters located at least partially within the lumen of an outer sheath. The outer sheath and the catheters are configured to slide relative to each other between a first state in which the distal ends of the catheters are located within the lumen of the outer sheath, and a second state in which the distal end and an end length section of each catheter is extended through the distal end of the outer sheath and outside of the lumen of the outer sheath. The end length section of each catheter is configured to spring or flare outward relative to the first state, when the outer sheath and the plurality of catheters are in the second state. The distal end of the outer sheath may be placed in an inferior vena cava or iliac vein in a transplant kidney patient, adjacent at least one renal vein, with the outer sheath and the plurality of catheters in the first state. Then, the system may be transitioned to the second state to cause the end length sections of the catheters to spring or flare outward adjacent the renal vein. The catheters are connected to a suction source for aspiration through the catheter end length sections.

摘要： The present disclosure relates to a motor for an extracorporeal blood pump, an extracorporeal blood pump, and an extracorporeal blood pump system. The motor for an extracorporeal blood pump comprises: a housing; an actuator located in the housing and used for driving an impeller in a pump head of the extracorporeal blood pump; at least one sensor located in the housing; and a motor driving-control assembly located in the housing and used to control operation of the motor. Integrating the motor driving-control assembly into the housing of the motor can significantly reduce the dependence of the motor on the control host of the extracorporeal blood pump, the risk of communication failure between the motor and the control host, and the risk of malfunction of the motor driving-control assembly, thereby greatly improving the safety and reliability of the extracorporeal blood pump.

摘要： A cardiac assist system includes a pneumatic effector which is implanted beneath a pericardial sac and over a myocardial surface overlying the patient's left ventricle. A port is implanted and receives a percutaneously introduced cannula. The port is connected to supply a driving gas received from the cannula to the pneumatic effector. An external drive unit includes a pump assembly and control circuitry which operate the pump to actuate the pneumatic effector in response to the patient's sensed heart rhythm. A connecting tube has a pump end connected to the pump and a percutaneous port-connecting end attached to the implantable port.

摘要： Provided is a chamber configuration for a reverse flow centrifuge, and a reverse flow centrifuge system configured for low fluid volume and small radius rotation. The compact reverse flow centrifuge system has a reusable subsystem and a single use replaceable subsystem. The replaceable subsystem comprises a separation chamber, fluid delivery manifold and rotational mounting connecting the separation chamber to the fluid manifold. The single use replaceable subsystem provides a closed environment for execution of reverse flow centrifugation processes. The separation chamber has a substantially conical fluid enclosure portion connected to a neck portion, and a dip tube extends centrally through the conical fluid enclosure to provide a fluid path to the tip of the conical fluid enclosure.

摘要： A blood pump system for persistently increasing the overall diameter and lumen diameter of peripheral veins and arteries by persistently increasing the speed of blood and the wall shear stress in a peripheral vein or artery for a period of time sufficient to result in a persistent increase in the overall diameter and lumen diameter of the vessel is provided. The blood pump system includes a blood pump, blood conduit(s), a control system with optional sensors, and a power source. The pump system is configured to connect to the vascular system in a patient and pump blood at a desired rate and pulsatility. The pumping of blood is monitored and adjusted, as necessary, to maintain the desired elevated blood speed, wall shear stress, and desired pulsatility in the target vessel to optimize the rate and extent of persistent increase in the overall diameter and lumen diameter of the target vessel.
