Abstract: The present invention relates to a surgical device (1) comprising: an elongate, flexible and tubular arm (3) having a distal end and a proximal end; a flexible pulling means (6) which is arranged inside the arm (3); a tool (4) which is arranged at the distal end of the arm (3) and which comprises at least two parts (11,12), which are operable by said pulling means (6); and an operating means (15) which is arranged at the proximal end of the arm to operate said pulling means (6) and, thus, said tool (4). The invention is characterised in that said arm (3) is made of a material, which resumes its shape by heating and which has a transformation temperature which allows the arm (3) to be deformable to the desired shape at room temperature and to keep the thus obtained shape at a patient's body temperature during use of the device (1), so as then to allow resumption of its original shape when exposed to a temperature exceeding the body temperature.

Abstract: A valve device to enable aseptic injection and withdrawal of medical fluids into/from an infusion container. The valve device comprises a valve body with self-sealing passage portion (2), a surrounding portion (3) and a peripheral portion (4), and has an adhesive application surface (5). Located at the underside of the passage portion is a pressure relief zone (6), and at the upper side an insert zone (7). The surrounding portion (3) has a pronounced upright edge. The valve device is manufactured in one piece of the same material and can be simply applied and handled on the occasion of use while retaining aseptic conditions even by persons of impaired sight.
