The first sub controller and the second sub controller are detachably connected by a first pipe joint and a fourth pipe joint.

A blood pump with an integrated flow sensor is provided. The blood pump may include an implantable pump for pumping blood having a housing, a flow path extending within the housing and at least one movable element within the housing for impelling blood along the flow path and a sensor for measuring the flow rate of blood through the pump. According to one embodiment, the sensor may be mounted to the housing of the pump. In accordance with a further embodiment, the housing may have an exterior surface defining a cavity, and the sensor may be located within the cavity.

A disclosed apparatus or method can include or use a non-transluminally implantantable blood pump housing, which can be sized and shaped to be implanted at an aortic valve of a human subject, the pump housing can include: a pump housing cross-sectional profile size that is larger than is passable via a blood vessel of the human subject; and a power connection, configured for being electrically connected to an intravascular lead that is sized and shaped to extend from the pump housing through a subclavian artery of the human subject.

A bearingless and sealless rotary blood pump is disclosed which provides multidirectional flow intended to provide low-pressure, high-volume right-sided partial assist circulatory support in a univentricular Fontan circulation on a permanent basis. The pump includes a housing and an impeller suspended in the center of the housing. The housing incorporates flow optimization features between inlet and outlet ends, as well as with the impeller surface. Large fluid gaps maintained between impeller and housing eliminate any potential for blood flow obstruction. The impeller contains some motor components. It includes a central stator and surrounding rotor. The motor includes a brushless DC outrunner electrical motor design. An electromagnetic stator core is surrounded by a circumferential passive magnetic ring. The rotor is further levitated about the stator spindle by a plurality of axially and radially located passive magnetic and hydrodynamic journal bearings on both ends of the spindle. The rotor is bearingless and sealless. During impeller rotation, blood entering the space between the rotor and stator is induced to flow by centrifugal pumping action and the fluid film separates the stator hydrodynamic bearings from the rotor so that there is no direct mechanical contact between the rotor and stator.

A cardiac assistance system is provided that comprises two pumps and cannulae connected thereto. A first pump of the two pumps is configured to connect to a right heart system via a first fluid channel. The first fluid channel formed at least partially by a first two cannulae of the cannulae. A second pump of the two pumps is configured to connect to a left heart system via a second fluid channel. The second fluid channel formed at least partially by a second two of the cannulae. The two pumps are configured as rotary pumps for arrangement outside a patient's body.

Various embodiments of a system for priming a catheter assembly are disclosed herein. For example, the system can include a catheter assembly including an elongate body and an operative device coupled thereto. The system can also include a priming vessel configured to receive insertion of the operative device therein. The priming vessel can include a proximal portion secured to the distal portion of the elongate body such that the elongate body is in fluid communication with the priming vessel. The priming vessel can also include a distal end through which air is expelled when a fluid is channeled through the elongate body and into the priming vessel to expel air from within the catheter assembly.

A disclosed apparatus or method can include or use a non-transluminally implantantable blood pump housing, which can be sized and shaped to be implanted at an aortic valve of a human subject, the pump housing can include: a pump housing cross-sectional profile size that is larger than is passable via a blood vessel of the human subject; and a power connection, configured for being electrically connected to an intravascular lead that is sized and shaped to extend from the pump housing through a subclavian artery of the human subject.

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.

An implantable pump system can deliver blood within the body of a patient, with a blood pump which delivers a fluid in an axial direction. The blood pump can include a rotatingly drivable rotor as well as a pump casing surrounding the rotor, as well as a support tube, in which the pump casing is arranged and held, wherein an annular gap is formed between the support tube and the pump casing. An almost physiological blood flow is rendered possible in this manner, by way of the combination of a flow through the pump casing on the one hand, and the annular gap on the other hand.
