Abstract: An apparatus, device and method are provided for endoscopically extracting multiple tissue samples from multiple locations without needing to completely retract the apparatus or device from the target tissue in the process. In some embodiments the device includes a sheath for delivering the device through a body lumen wall, an outer needle, an inner needle extendable from and retractable into the outer needle, the inner needle having a rotational feature to enable sequential entry of the inner needle at multiple angles relative to the outer needle; and a rotational control mechanism for controlling rotation of the inner needle thereby enabling tissue extraction from multiple locations in a target tissue, without sequentially exiting the body lumen wall.
