A device for gathering tissue samples includes a needle defining a distal tissue penetrating tip. The needle includes an increased diameter proximal portion extending proximally from the distal tip. An outer diameter of the distal tip is smaller than an outer diameter of the proximal portion. The needle defines a lumen extending therethrough from a distal opening in the distal tip thereof to a proximal opening at a proximal end thereof. The lumen includes a distal portion having a first inner diameter and a proximal portion having a second diameter greater than the first diameter. The device also includes a stylet slidably received within the lumen. An outer diameter of a distal portion of the stylet is substantially equal to the inner diameter of the distal portion of the lumen so that, when the stylet is in an extended position extending to the distal opening of the lumen, the lumen is substantially sealed thereby, and when, in a retracted position in which a distal end of the stylet is received within the proximal portion of the lumen, an annular space surrounding the stylet defines an aspiration path for samples exiting the distal portion of the lumen.
