Abstract
A biopsy device for acquiring more than one tissue sample is disclosed. The biopsy device can have at least two tissue engaging elements, where at least one element contains a helical feature. A control mechanism can be used to spin an outer element relative to an internal element, resulting in transport of multiple tissue samples from the mass of tissue to an accessible collection chamber. The outer element may have a sharp distal end which may sever the samples from the mass of tissue. Samples may be stored sequentially in the collection chamber and be removed by the operator.
