ABSTRACT:
A preassembled PBY circuit includes a blood pump, an oxygenator, a blood line, a filter/trap, a cannulae line subassembly, and a return line. The blood pump, oxygenator, blood line, filter/trap, cannulae line subassembly, and return line are serially arranged in a closed loop configuration, and a prime line is attached in fluid communication with the circuit. The cannulae line subassembly includes a first cannula line attached to the return line, a second cannula line attached to the filter/trap, and a removable connector for connecting the first and second cannulae lines in fluid communication. Each of the cannulae lines is prearranged in a helical configuration. The circuit is arranged for suspension, such that, when suspended, the filter/trap is located at a high point of the circuit, and the prime line is attached at a low point of the circuit. In this manner, priming fluid is introduced through the prime line, enters at a low point of the circuit, and fills the circuit in a bottom-to-top priming operation.
