Abstract: A biopsy apparatus includes a biopsy probe having a biopsy cannula and a sample basket arranged coaxially about a longitudinal axis. The sample basket is movably disposed relative to the biopsy cannula along the longitudinal axis from a tissue harvesting position to a tissue sample retrieval region. The sample basket has a sample notch formed as an elongate recessed region for receiving a tissue sample. A tissue sample retrieval mechanism includes a sample collection tank configured for removable insertion into a sample tank receptacle. The sample tank receptacle permits movement of the sample collection tank in a direction perpendicular to the longitudinal axis and prohibits movement of the sample collection tank in a direction along the longitudinal axis. The sample collection tank is configured to retrieve the tissue sample directly from the sample notch as the sample basket is moving along the longitudinal axis at the tissue sample retrieval region.

Abstract: A biopsy system for harvesting tissue samples from a suspect tissue mass in a body of a living being, e.g. in per-cutaneous aspiration biopsy, comprises a hollow needle (50) and a sample-receiving device (52), which is movable in the hollow needle. A first user-operable firing mechanism (110) is provided for causing the hollow needle and the sample-receiving device to be substantially simultaneously displaced in a distal direction, so as to penetrate body tissue at or near the suspect tissue mass. A second user-operable firing mechanism (112) may cause the hollow needle solely to be longitudinally displaced in a distal direction from a position, in which the sample-receiving device (52) projects from the distal end of the hollow needle (50), to a position, in which the hollow needle essentially accommodates the sample-receiving device, so as to sever said tissue sample from remaining body tissue at the harvesting site.

Abstract: According to the present invention, there is provided a hearing aid insert module comprising a socket module, and a substantially closed-loop frame comprising electrically conductive portions, the closed-loop frame further comprising engaging means adapted to releasably couple the hearing aid insert module to a faceplate of a hearing aid. The invention is of advantage in that releasable coupling of the faceplate to the socket module via the frame is capable of rendering the insert module easier to manufacture, to user-customize and to repair. The frame is arranged to impart a majority of structural rigidity to the faceplate when inserted therein. Such rigidity is of benefit in that the faceplate is capable in use of applying a flexural component to the frame which could damage the frame if not of sufficiently substantial rigidity.
