Abstract
An embodiment of the invention includes a device for collecting body tissue. The device may include an inner member comprising a hollow portion to collect body tissue and a distal end configured to both penetrate body tissue and define an opening of the hollow portion. The device may further include an outer member, co-axially and slidably disposed around the exterior of the inner member, comprising a distal end portion. The distal end portion of the outer member may be configured to penetrate body tissue, prevent body tissue from exiting the hollow portion of the inner member, and allow the distal end of the inner member to extend beyond the distal end of outer member. The opening of the hollow portion of the inner member may be disposed in a plane that is not perpendicular to the longitudinal axis of the inner member.
