Abstract
A roller pump includes a roller pump rotor including a first roller arm having a first roller rotatably coupled thereto and a second roller arm having a second roller rotatably coupled thereto, a raceway disposed around the rotor, a pump motor configured to rotate the rotor relative to the raceway, and an electronic actuator disposed on the rotor, wherein the actuator is configured to change a radial position of the first and second rollers. The actuator may be couplable to the motor such that the motor is capable of rotating the rotor and changing the radial position of the first and second rollers. An extracorporeal perfusion system includes a fluid reservoir, an oxygenator, flexible tubing coupling the reservoir to the oxygenator, and the roller pump, wherein the flexible tubing is disposed within the raceway. The motor is configured to rotate the rotor to cause fluid to flow within the tubing.
