A connecting piece having a transfer apparatus for data transfer and/or for transferring electrical energy with the counter connecting piece. A connecting piece of this type is preferably used in an intelligent medical fluid conduction and transfer system, in which various components are interconnected by means of the connecting pieces not only fluidically but also for the purpose of transferring energy and/or data with each other, such that, for example, information regarding the medication can be exchanged or validated.

A percutaneous catheter includes an expansion portion, a shaft portion, and an intermediate portion. The expansion portion includes a first reinforcing body including wires braided so as to intersect with each other. The shaft portion includes a second reinforcing body including the wires braided so as to intersect with each other. The intermediate portion includes a third reinforcing body including the wires braided so as to intersect with each other. The third reinforcing body is configured to have a braiding angle as an inner angle in an axial direction among angles formed by the intersecting wires which is smaller than those of the first reinforcing body and the second reinforcing body.

A blood treatment system includes (i) a blood pump including a first blood pump chamber operable with a first inlet valve and a first outlet valve, and a second blood pump chamber operable with a second inlet valve and a second outlet valve; (ii) an arterial blood line; (iii) a dialyzer placed in fluid communication with the arterial blood line, wherein the blood pump is provided along the arterial blood line upstream of the dialyzer; and (iv) a venous blood line extending downstream from the dialyzer. The system also includes a processor configured to sequence the first and second blood pump chambers so as to achieve a pulsatile pattern of filling the first and second blood pump chambers and an at least substantially constant pattern of discharging blood from the first and second blood pump chambers to the dialyzer.

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.

Embodiments of the present invention provide an extra corporeal membrane oxygenation circuit, wherein a pump communicates blood from a patient to an oxygenator and thence back to the patient, comprising: (a) a medium diameter venous line configured to accept blood from the patient and communicate the blood to the pump; (b) a medium diameter arterial line configured to accept blood from the oxygenator and communicate the blood to the patient; (c) one or more shunts connected in a series, where each shunt comprises a medium diameter input connected to a medium diameter output, where the medium diameter output is configured to connect to a medium diameter input of a successive shunt; a small diameter outlet between the medium diameter input and the medium diameter output; and a stopcock connected to the small diameter output such that flow out of the small diameter outlet can be controlled by the stopcock; wherein a first of such shunts is connected to accept blood from the venous line in parallel with the pump and wherein a last of such shunts is connected to communicate blood to the arterial line.

An extension cannula and in-line connector for use with a conventional ECMO return cannula is provided. The extension cannula includes a flexible conduit transitionable between a collapsed insertion state and an expanded deployed state when in communication with blow flow from an ECMO machine via the ECMO return cannula. The extension cannula may be positioned through a conventional ECMO return cannula such that the proximal end of the flexible conduit is disposed within and proximal to the end of the ECMO return cannula, while the distal end of the flexible conduit is disposed in a patient's thoracic aorta to deliver oxygenated blood directly to the patient's thoracic aorta via one or more pores at the distal region of the flexible conduit to improve cerebral oxygenation, maintain systemic arterial pulsatility, and reduce the potential for end-organ injury.

An autologous perfusion fluid collection reservoir basin includes a basin body configured to receive an extracorporeal organ and blood and includes a sloped bottom. The sloped bottom is configured to channel fluid toward an outlet port. The autologous perfusion fluid collection reservoir basin also includes a connector that extends from the outlet port. The connector is configured to connect to tubing of a cardiopulmonary bypass system or to enable direct connection to a cardiopulmonary bypass system.

The present invention relates to a system (5) for temperature management for patients in stationary and mobile ECLS and/or ECMO therapy, with at least one disposable (7) and a fluid circuit (9), wherein the disposable (7) comprises at least one reservoir (10) or bag provided with at least one supply line (12) and a drain line (14), further provided at least one pumping unit element (11) as part of the disposable (7), by means of which liquid in the reservoir (10) or bag can be pumped through the fluid circuit (9).

Furthermore, the present invention relates to a disposable (7) for such a system (5).

A pump device includes an impeller and a housing that houses the impeller in a rotatable manner. The impeller includes a fin (vane) unit and a movable sleeve. The housing includes a fixed sleeve that houses the movable sleeve. A first gap is formed between an inner periphery of the movable sleeve and an opposing surface that faces the inner periphery. Since the inner periphery and the opposing surface are inclined relative to an axis of the impeller, the first gap is increased when the impeller ascends with rotation of the impeller.
