Abstract
A peristaltic pump for an implantable medical device includes a pump tube defining an axis lying along a path in a first plane. Spherical rollers compress the tube at one or more points along the path in a direction non-parallel to the first plane, and preferably perpendicular to the first plane. Means for driving the rollers are provided so that liquid is moved through the tube.
