Claim 0:
1. A soft tissue biopsy device comprising:
an elongated flexible shaft having an internal lumen and a distal end, wherein said elongated flexible shaft is shaped and sized to be introduced via a working channel of an endoscope into a body;
a distal cylindrical hollow sampling portion coupled to said elongated flexible shaft distal end, having a flat distal end, a wall defining and surrounding an enclosed internal lumen, a distal round front opening to said enclosed internal lumen at said flat distal end, and a circumferential round cutting edge surrounding said distal round front opening, wherein said circumferential round cutting edge is shaped and sized to form a round cut in said soft body tissue when penetrating into said soft body tissue, wherein said distal cylindrical hollow sampling portion is configured to cut through soft body tissue while penetrating into said soft body tissue, and to apply forces on tissue positioned inside said internal lumen of said distal cylindrical hollow sampling portion that are sufficient to separate tissue inside said internal lumen from the soft body tissue outside said distal cylindrical hollow sampling portion;
at least one motor functionally coupled to said elongated flexible shaft configured to rotate and axially advance in synchronization and in a fixed ratio said elongated flexible shaft and said distal cylindrical hollow sampling portion comprising said circumferential round cutting leading edge, into the tissue, wherein the rotation of the distal cylindrical hollow sampling portion separates a tissue sample from the soft body tissue.
