Oxygenator with improved blood mixing

Abstract

An oxygenator may include a housing extending from a first end to a second end along a central longitudinal axis, a first end cap, a second end cap, and a bundle of hollow gas exchange fibers extending between the first end and the second end. The first end cap and the second end cap may each be rotatable about the central longitudinal axis. An oxygenator may include a bundle of hollow gas exchange fibers extending from the first end cap to the second end cap. An oxygenator may include a housing including a first axially expandable portion, a second axially expandable portion, and a rigid tubular portion disposed between and fixedly attached to the first and second axially expandable portions. An oxygenator may include a bundle of hollow gas exchange fibers may be axially movable relative to the housing.
