Abstract
A self-contained pack assembly includes all of the disposable components of an extracorporeal support circuit for cardiac bypass surgery. The pack assembly comprises a blood reservoir, a blood oxygenator, and a carrier for vertically mounting the blood reservoir and blood oxygenator. Trays may be releasably attached to the carrier to serve as containers for coiled tubing used in the support circuit.
