Abstract: A biopsy needle assembly includes a mandrel within a cannula, the needle assembly is fired into a target tissue to obtain a tissue sample using a force source imparting movement to the needle assembly. The mandrel and cannula design, and force source characteristics minimize needle deflection, and allow the needle assembly to excise extended length tissue samples. The mandrel forms tissue retention ridges within a tissue sample region to reduce fragmentation of the tissue sample.

Abstract: A biopsy needle actuator includes an adjustable stop plate setting the distance a needle and cannula move when the actuator is fired, a shot counter tracking the number of shots taken with the actuator during a biopsy procedure, and a lifecycle indicator tracking the cumulative number of shots of the actuator during a recommended service life. A threaded rod sets the throw distance of the needle and cannula allowing the actuator to excise a biopsy tissue specimen of between 20 mm and 60 mm. A number wheel in the shot counter is moved upon firing of a needle carrier. The lifecycle indicator registers arming of the actuator and indicates when the mechanical components of the actuator need servicing. A biopsy needle within a cannula is mounted in the actuator where by the core bed of the needle is orientated downward when in use aiding in extraction of the tissue sample.

Abstract: Disclosed is a biopsy specimen carrier adapted for tissue biopsy samples where the specimen need not be removed or handled once housed within and including a backer board, a media removable secured to the backer board, a media carrier removable secured to the media and receptive to hold a tissue biopsy sample, a first strip of adhesive material on the media adjacent to the media carrier, and a release strip covering the first strip of adhesive material. The media is foldable to cover the media carrier carrying a tissue biopsy sample and is secured to the first strip of adhesive material with the release strip removed.
