A biopsy device includes a longitudinal element sufficiently flexible to permit insertion into a body. The longitudinal element extends from a proximal end to a distal end and includes a lumen extending therethrough. The device also includes a stylet slidably received within the lumen having a distal end split into a pair of arms biased away from one another so that, when distal end of the stylet is advanced out of a distal end of the longitudinal element, the arms separate from one another into a tissue receiving configuration, the stylet including a tissue receiving space between the arms. The stylet is coupled to a handle via which the stylet is drawn proximally into the lumen of the longitudinal element so that contact between the longitudinal element and the arms draws the arms toward one another into a tissue capture configuration in which tissue is gripped therebetween. |
