Claim 15:
16. A method for sampling soft tissue, comprising:
introducing an elongated flexible shaft and a sampling needle coupled to said elongated flexible shaft into a body via a working channel of an endoscope, wherein said sampling needle comprises a distal cylindrical hollow sampling portion having a flat end, an internal lumen and a distal opening, and a circumferential round cutting leading edge at the flat end and surrounding said distal opening, wherein said circumferential round cutting leading edge is shaped and sized to cut through soft body tissue when advancing said sampling needle into soft body tissue;
rotating said elongated flexible shaft and said sampling needle;
axially advancing said elongated flexible shaft and said sampling needle during said rotating into soft tissue in synchronization with said rotating and in a fixed ratio between said rotating and said axially advancing, while introducing a portion of said soft body tissue into said internal lumen through said distal opening;
sampling said soft body tissue by applying forces on said soft body tissue portion during said rotating, wherein said rotating and said forces separate a tissue sample from said soft tissue.
