The apparatus is provided with a connector part at which the affixing device is located to mate with the proximal end of the electrode cable. The affixing device includes a spring element which is disposed substantially perpendicularly to the longitudinal axis of the proximal end of the electrode cable when the proximal end is contained in the connector part. The spring element carries clamping elements, and the spring element is movable between first and second positions. When the spring element is in the first position, the clamping elements are caused to be disposed so as to permit the proximal end of the electrode cable to pass the clamping elements, and when the spring element is in the second position, the clamping elements are caused to engage the proximal end of the electrode cable to affix the proximal end in the connector part. The affixing device has a simple structure, which is inexpensive to manufacture, and which is simple to handle during implantation while still providing good and reliable electrical contact between the electrode cable and the apparatus.
I claim as my invention: 1. A device for affixing an electrode cable to an apparatus for emitting electrical pulses, said apparatus having a connector part and said electrode cable having a pin-shape proximal end having a longitudinal axis adapted to be received in said connector part and comprising:a spring element extending substantially perpendicularly to said longitudinal axis of said proximal end of said electrode cable; a plurality of clamping elements carried by said spring element; and said spring element being movable between a first position at which said spring element holds all of said clamping elements at respective first locations to permit said proximal end of said electrode cable to pass said clamping elements and being activatable into a second position by interaction with said electrode cable at which said spring element holds all of said clamping elements at respective second locations so as to engage and affix said proximal end of said electrode cable. 2. A device as claimed in claim 1 wherein said spring element comprises a convex disk having a bulge, said bulge in said first position facing said proximal end of said electrode cable and in said second position facing away from said proximal end of said electrode cable.
SUMMARY OF THE INVENTION It is an object of the present invention to provide an affixing device for affixing the proximal end of an electrode cable to an apparatus which emits electrical energy, which has a simple structure, is inexpensive to manufacture, and which can be operated in a simple manner while simultaneously providing good affixing of the electrode cable. It is a further object of the present invention to provide such an affixing device which achieves reliable electrical contact between the electrode cable and the apparatus.
DESCRIPTION OF THE DRAWINGS FIGS. 1 and 2 are side schematic views of a connector part of an apparatus for emitting electrical pulses, with a fixing device constructed in accordance with the principles of the present invention shown in cross-section, the spring element of the affixing device being respectively shown in first and second positions in the figures.
DESCRIPTION OF THE PREFERRED EMBODIMENTS In FIG. 1, the outline of an apparatus for emitting electrical pulses, in the form of a pacemaker 1, is shown in dashed lines. The outlined portion includes a stimulation pulse generator part 2 and a connector part 3. An affixing device 4 constructed in accordance with the principles of the present invention is contained in the connector part 3. The affixing device 4 is arranged for affixing the pin-like proximal end of an electrode cable 5 for a pacemaker electrode. The affixing device 4 includes a spring element 6, in the form of a convex, substantially spherical disk. The spring element or disk 6 is provided with spherical clamping elements 7, which are uniformly distributed around the edge of the disk 6. The affixing device 4 is contained in a hood 8, having the shape of a truncated cone, whose base is attached to the stimulation pulse generator part 2. The largest diameter of the hood 8 is only slightly larger than the outer dimension of the disk 6 when the disk assumes an extended, first position described below. The slope of the truncated cone, i.e., the orientation of the inner wall of the hood 8, is selected so that it roughly follows a curve describing the peripheral surface of the affixing element 4 when the affixing element 4 moves from the extended, first position to a second, clamping position. The hood 8 serves to hold the loosely arranged spring element 8 and the spherical clamping elements 7 inside the hood 8, so that the spring element 6 is always substantially perpendicular to the longitudinal axis of the proximal end of the electrode cable 5 introduced into the connector part 3. The affixing device 4 is made of an electrically conductive material, and is electrically coupled via a conductor 9 to an electrically contact 10 in the stimulation pulse generating electronics contained within stimulation generator part 2. If the pacemaker electrode is bipolar, a contact part 12, coupled to an electrical contact 14 in the stimulation pulse generator in the stimulation pulse generator part 2, is also arranged in a channel 11 of the connector part 3. Coupling the contacts 10 and 14 is achieved in a known manner, and will therefore not be shown or described in further detail.
