Patent ID: 8192370

Claim:
A biopsy apparatus, comprising: a disposable cutting element and a reusable handpiece; wherein the disposable cutting element includes an outer cannula defining an outer lumen, a tissue-receiving opening proximate a distal end of the outer cannula communicating with the outer lumen, and an inner cannula slidably disposed within the outer lumen and defining an inner lumen from an open distal end to an open proximal end opposite the distal end, wherein the inner cannula includes a cutting edge at the open distal end operable to sever tissue projecting through the tissue-receiving opening, and a tissue aspiration path in the inner lumen, the tissue aspiration path extending from the open distal end of the inner cannula to the open proximal end of the inner cannula to allow a tissue sample to be aspirated from the open distal end of the inner cannula to the open proximal end of the inner cannula; and wherein the reusable handpiece includes a first MRI compatible device detachably coupled to the inner cannula to rotate the inner cannula within the outer cannula, and a second MRI compatible device detachably coupled to the inner cannula to translate the inner cannula within the outer cannula while the inner cannula rotates.
