Abstract:
1. A biopsy device, comprising: a handpiece; a cannula operatively coupled with the handpiece, the cannula having a distal end; a sampling portion of the biopsy device operatively coupled with the distal end of the cannula, the sampling portion comprising a first component and a second component moveable relative to the first component, a wall of the first component defining an interior channel between outer and inner surfaces of the wall of the first component, wherein in a first position the sampling portion is closed, and in a second position the sampling portion is open; a first device configured to form a pressure gradient in the biopsy device, the first device being in fluid communication with at least one orifice in the sampling portion through the interior channel of the first component, so that, during use of the first device, the first device forms a pressure gradient in a direction non-parallel to a longitudinal axis of the sampling portion; and a second device configured to form a pressure gradient in the biopsy device, the second device being operatively coupled with the sampling portion so that, during use of the second device, the second device forms a pressure gradient in a direction substantially parallel to the longitudinal axis of the sampling portion.
