Abstract: An applicator for use in the fitting of an occlusive plug of the screw in kind to a fallopian tube, said applicator comprising: a body member; an eyepiece fitted to one end of the body member; an elongate probe carried by, and projecting from the other end of the body member; a fibre optic cable extending from the eye-piece along the interior of the probe to a terminal end of the probe distal from the body member; a nose piece movably mounted at said distal end of the probe and adapted to releasably receive a rear, drive end of an occlusive plug; a mechanical connection extending between the body member and the nose-piece whereby the practitioner may, within limits, vary the angle of the nose-piece with respect to its carrier tube; and a rotational drive means extending between the body member and the nose-piece to apply torque & hence rotational movement to an occlusive plug temporarily held by the nose-piece.

Abstract: A plug (1) for use in occluding a fallopian tube hysteroscopically comprising an elongate body (2) having an external thread (3) characterised in that the body and/or external thread has/have a roughened and/or pitted external surface (4), or in that the thread is fenestrated (5), or in that the leading end (6) of the elongate body (2) is provided with an extension nose (7) having a smooth external surface (8) and a rounded terminal end (9), or in that the leading end (6) of the elongate body (2) is provided with a conic helix (11) of the same hand as the external thread (3), generally forming a continuation of the external thread (3). The invention also includes a drive tool, for inserting a plug (1) incorporating an integral flexible hysteroscope, and comprising an outer sleeve housing a flexible drive rod adapted, at one end to engage, and apply torque to, the trailing end (12,13) of the elongate body (2) of the plug (1), with the other end of the drive rod being manually rotatable by the surgeon.
