ABSTRACT:
A medical device for obtaining biopsy tissue samples is provided includes a flexible outer tubular member having proximal and distal ends, and an inner tubular member slidably and coaxially received within the outer tubular member and a stylet slidably and coaxially received within the inner tubular member. A spring member coaxially oriented about the stylet has a proximal end attached to the stylet and a distal end attached to an outer hollow needle member. The inner hollow needle is attached to the distal end of the stylet to effect reciprocal movement thereof. The device has a retracted position, a first extended position wherein the outer hollow needle and a first portion of the inner needle are deployed beyond the distal end of the device, and a second extended position wherein a second length of the inner needle is deployed beyond the distal end of the device.
