Patent ID: 8889406

Claim:
An apparatus for cultivating cells in a container utilizing wave motion of a liquid medium comprising: a container for cultivating cells; a retaining member configured to retain the container and be positioned and operated above a first plane; a substantially horizontal pivot axis about which the retaining member pivots, the substantially horizontal pivot axis extending parallel to the first plane; and a drive assembly configured to drive the container with respect to the substantially horizontal pivot axis, wherein the drive assembly is configured to swivel the container such that during said swiveling said substantially horizontal pivot axis follows a cyclical closed-loop path that extends along a second plane, the second plane extending perpendicular to the substantially horizontal pivot axis and perpendicular to the first plane; and a movement vector of the substantially horizontal pivot axis along the closed loop path is in a plane that is the same as a movement vector of waves generated in the container when the container is swiveled.
