According to some embodiments, a system may treat blood outside the body of a patient. The system may include one or more pumps configured to draw blood from a patient into a fluid flow path at a rate, for example, of 5-7 liters per minute. The system may include one or more heat exchangers coupled to the fluid flow path and configured to heat the blood, for example, to a temperature above 42 degrees Celsius and below 43.2 degrees Celsius.

A fluid connector can include a first connector having a first passageway and a second passageway; and a second connector having a third passageway and a fourth passageway. The first connector can be attracted to the second connector through a magnetic force, thereby forming the fluid connector. Moreover, when the first connector abuts the second connector, the first passageway together with the third passageway can form a first fluid path, and the second passageway together with the fourth passageway can form a second fluid path that is different from the first fluid path.

Systems and methods for delivering a gas, such as nitric oxide, are provided. In some embodiments, systems and methods are provided for delivering a gas, such as nitric oxide, in the form of nanobubbles and/or a dissolved gas using a liquid medium.

An active implantable medical device (AIMD) is described. The AIMD comprises: a drug chamber that comprises a drug; a motor chamber that comprises a housing, a motor, and a driving component; a piston that is affixed to a first end of the driving component; and an electronic module that actuates the motor to operate the driving component and move the piston longitudinally to discharge the drug outside the AIMD through one or more orifices.
