TISSUE ACQUISITION SYSTEM AND METHOD OF USE

摘要

A tissue acquisition system (100) includes radio frequency cutter loops (138 ) which are extendable out a cannula (116) to cut cylindrical tissue samples from a tissue of interest in a patient. The cannula includes inner and outer cannulae (116, 152) which are mutually rotatable and include cutouts (124) through which the cutting loop (138) can be rotated, and longitudinally extended to perform the cuts. The tissue samples are then aspirated proximal ly through the cannula for collection.
