Abstract
This is a device for percutaneous tissue sampling or excision. In particular, it uses a rotating cutter which produces a helically cut, discrete tissue mass that is removable through a comparatively much smaller access member. The tissue mass is easily reconstructed to its original form and orientation once taken from the body for further study.
