Abstract: A device for fastening an electrode in the pacemaker bed before the entry of the electrode into a vein is provided, and includes a sheath having two parts and, with a hose extending through their interior. The two parts and of the sheath are profiled at the contacting edges of a common separating point so that they are fixed in reference to one another in the rotational direction until a user pulls them apart beyond the axial extension of the profiling. In this pulled-apart position the parts of the sheath can be rotated in reference to one another under torsion of the hose and subsequently, due to the restoring force of the hose, will be again guided together axially, which reduces the interior cross-section of the hose and allows a form-fitting grasping the electrode extending therethrough.

Abstract: A device (1) serves for creating perforations, borings or perfusion channels in the heart wall (2), especially in the myocardium, for generating channels running in the heart wall (2) for supplying it with blood. So that the chest cavity need not be opened in an operation for introducing such perforations, the device (1) has a catheter (4) introducible intracardially into the heart (3), which has at least one electrode or pole on its operating end and has a connection of this electrode or pole to a high frequency generator (5). Moreover, this distal operating end has at least one needle (6) insertible into the heart wall (2) from the inside, which needle functions as a coagulation tool, so that the lumen of the channel generated by it remains open and can be supplied with fresh blood from the interior of the heart (3).

Abstract: A balloon-free dilatation catheter has an elongated flexible sheath which is insertable into an animal body so that its distal end is located at or within a selected portion of an internal passage, such as in a blood vessel. The distal end normally confines an elongated cage-like expander having elongated at least partially resilient expanding elements which store energy when confined within the distal end but expand and bear against the tissue surrounding the selected portion of the internal passage when expelled from the distal end by one or more sleeve-like displacing elements confined in and movable circumferentially and/or longitudinally of the sheath. The expanding elements can carry one or more thermometers and/or the discharge end(s) of one or more conduits for a medication or another flowable substance and/or they can be connected to an energy source, e.g., to cool or heat and/or otherwise treat the tissue.

Abstract: The electrical connector (1) with a socket section (2) and a plug section (3) contains a clip (4) by which the pin (5) of the plug section (3) can be clamped in the axial direction and secured against unintentional withdrawal. In addition there is protection against contact with the live parts of the connector (1) which nevertheless permits the rotation of the clip (4) so that it can be closed and opened. Essentially, the plug section (2) has a sleeve (13) which surrounds the pin (5) externally and in spaced relationship to it and is rotatable in relation to the plug section (2), which sleeve (13) is of such an axial length and inner dimensions that, with the pin (5) inserted into the clip (4), the sleeve (13) is axially movably pushed in an axial direction onto the component serving to rotate the conical section (6) of the clip (4) and at the same time is coupled thereto in the direction of rotation.
