Abstract
An apparatus is described for moving a probe (12) that engages moving living tissue such as a heart or an artery that is penetrated by the probe, which moves the probe in synchronism with the tissue to maintain the probe at a constant location with respect to the tissue. The apparatus includes a servo positioner (18) which moves a servo member (20) to maintain a constant distance from a sensed object (30) while applying very little force to the sensed object, and a follower (26) having a stirrup (28) at one end resting on a surface of the living tissue and another end carrying a sensed object (30) adjacent to the servo member. A probe holder (34) has one end mounted on the servo member (20) and another end which holds the probe (12). The probe is held adjacent to the stirrup (28) of the follower assembly, so that movements of the tissue and therefore of the follower assembly (26) result in corresponding movement of the probe (12) to follow the surface of the tissue.
