Abstract: The device comprises a guide element and an applicator which has a capsule adapted to accommodate an intravenous filter, a number of springs being located at the capsule base, said springs being so fashioned that their free ends are curved to define a pyriform body of revolution which encompasses the capsule. The applicator comprises also a conducting catheter, a sleeve installed on the catheter and so traversable as to get in contact with the springs, a stylet and a collet grip.

Abstract: The device includes a cathode assembly (1) having a housing (3) and an electrode (6) with a tapering portion (19), and an anode assembly (2) having a housing (20) and a nozzle (12) receiving the tapering portion (19) of the electrode (6), the nozzle (12) successively defining a cylindrical chamber (11), a tapering chamber (21), an arcing chamber (7) and a plasma jet forming chamber (23). The smaller end of the frustoconical tapering portion (19) of the electrode (6) is the end face of the electrode (6) received in the cylindrical and tapering chambers (11 and 21) so that the distance from the end face of the electrode (6) to the arcing chamber (7) equals 0.1 to 0.5 of the length of the tapering chamber (21), and the length of the tapering portion (19) of the electrode (6) is 3.5 to 4.5 times the diameter of the electrode (6).

Abstract: Disclosure is made of a surgical instrument, comprising a supporting body with a replaceable die, a magazine with staples, a carriage-holder, a staple ejector, a carriage-holder mechanical actuator, and a staple ejector mechanical actuator.The replaceable die is provided with a shaped guide plate corresponding to each of the suture types.The end surface of the magazine and of the staple ejector are also shaped so as to suit the type of suture being applied and to conform to the shape of a respective die.
