Apparatus and methods for obtaining biopsy samples using an endoscope
assembly are disclosed. In one embodiment, an assembly adapted for use
with an endoscopic insertion tube includes a sheath having a body portion
adapted to at least partially encapsulate a distal portion of the
insertion tube, and a biopsy sampling device attached to the sheath and
including a collection member proximate an end of the body portion. The
biopsy sampling device may be attached to the body portion of the sheath,
or alternately, may be attached to an enclosed distal end of the sheath.
The assembly may also include a cover attached to the sheath and
positionable proximate the biopsy sampling device. An actuation member
may be attached to the cover and may extend along the sheath, allowing
the operator to actuate the cover between a covered position and a
collecting position.
