Abstract

A biopsy device includes a cutter defining a cutter lumen and a tissue sample holder for collecting tissue samples. In one example, the tissue sample holder includes a rotatable manifold, and has a plurality of chambers that are each configured to separately hold tissue samples. A tissue sample holder rotation mechanism is operable to rotate the manifold to successively index each of the chambers with the cutter lumen. A sensing system is configured to sense the rotational position of the manifold. A controller in communication with both the sensing system and the rotation mechanism is operable to control the rotation mechanism based at least in part on the position of the manifold as sensed by the sensing system. The sensing system may include a sensor in a fixed position and a rotating encoder wheel on a shaft that is used to rotate the manifold.
