Abstract

A signal generator assembly having a signal generator and a preformed connector mechanically secured to each other. Posts extend from the signal generator into apertures in the connector. Orifices in the connector intersect the apertures and means are provided to engage the posts within the apertures through the orifices. In a preferred embodiment, the posts are provided with keyways and keys are inserted through the orifices to engage the keyways. The keys may be formed as wedges, preferably having a locking taper, to urge the connector and signal generator into firmer contact. A resilient cushion may be provided between the connector and the signal generator to enhance the interaction of the components.

Claims

1. In a body implantable signal generator assembly of the type having signal generator means having a surface, preformed connector means and mechanical securement means securing said connector means to the surface of said generator means, the improvement wherein said mechanical securement means comprises:

means extending from said signal generator means surface, said extending means including keyway means;

aperture means within said preformed connector means configured to accept said extending means;

orifice means angularly intersecting said aperture means; and

key means inserted in said keyway means through said orifice means, said key means comprising wedge means for urging said connector means toward said generator means surface with the degree of urging being in accordance with the depth of insertion of said key means within said keyway means.

2. The signal generator of claim 1 wherein there are at least first and second extending means, aperture means and orifice means, said aperture means being generally parallel and said orifice means being non-parallel to each other and said aperture means.

3. The signal generator of claim 2 wherein said extending means comprises post means.

4. The signal generator of claim 3 wherein said post means are generally parallel to each other, said orifice means being generally orthogonal to each other and said post means.

5. The signal generator of claim 2 wherein said orifice means are generally orthogonal to each other and said aperture means.

6. The signal generator assembly of claim 1 wherein said wedge means comprises locking taper means.

7. The signal generator assembly of claim 6 wherein said keyway means comprises an aperture through said extending means.

8. The signal generator of claim 1 further comprising resilient means intermediate said signal generator means surface and said connector means, said resilient means being in compression with the degree of the compressing force being dependent on the depth of insertion of said key means.

9. The signal generator of claim 1 wherein there is at least one extending means, aperture means, orifice means and engaging means.
