Abstract

A housing for a medical implant, such as a cardiac pacemaker, defibrillator, cardioverter, or the like, the housing having a hollow housing and a terminal housing attached to the hollow housing, which has at least one electrical terminal, which is situated in an externally accessible cavity of the terminal housing, for connecting an electrode line. The terminal housing is glued to the hollow housing using an adhesive, the plastic of the terminal housing containing polyurethane and/or polycarbonate and the adhesive being an epoxide or polyurethane.

Claims

1. A housing for a medical implant, such as a cardiac pacemaker, cardioverter/defibrillator, or a combination of a cardiac pacemaker and cardioverter/defibrillator comprising:

a housing;

said housing comprising a hollow housing and a terminal housing attached to said hollow housing;

said terminal housing comprising at least one electrical terminal which is situated in an externally accessible cavity of said terminal housing and configured to connect an electrode line wherein said terminal housing is configured from plastic;

said terminal housing coupled with said hollow housing with an adhesive;

wherein said plastic of said terminal housing contains polyurethane and/or polycarbonate or epoxide resin and wherein said adhesive is quick-curing.

2. The housing according to claim 1 wherein said quick-curing adhesive may be processed further for up to 15 minutes.

3. The housing according to claim 1 wherein said quick-curing adhesive is an epoxide or polyurethane.

4. The housing according to one claim 1 wherein said terminal housing is multipart and wherein parts selected from said terminal housing are coupled together using an adhesive.

5. The housing according to claim 1 wherein said terminal housing is transparent and allows a view of said at least one electrical terminal from outside of said terminal housing.

6. The housing according to claim 5 wherein said transparent plastic of said terminal housing contains polyurethane.

7. The housing according to claim 1 wherein said adhesive cures with an introduction of energy.

8. The housing according to claim 1 wherein said adhesive cures at temperatures of 200°

to 85°

C.

9. The housing according to claim 1 wherein said adhesive is an adhesive which cures upon irradiation using electromagnetic radiation.

10. The housing according to claim 9 wherein said plastic of said terminal housing has a transparency which is sufficiently high in wavelength range required to cure said adhesive to allow said adhesive to cure at a given irradiation intensity in at most four times of a duration specified for this irradiation intensity.

11. The housing according to claim 10 wherein said cure of said adhesive is activated by energy action and then proceeds independently.

12. The housing according to claim 1 further comprising a spacer in a size from 0.1 mm to 0.5 mm that is added to said adhesive.

13. The housing according to claim 1 wherein said terminal housing comprises two cavities on a side facing toward said hollow housing wherein said two cavities are configured to receive anchors attached to said hollow housing which together with said cavities cause precise positioning of said terminal housing in relation to said hollow housing before and when said terminal housing is coupled with said hollow housing.

14. The housing according to claim 1 wherein said electrical terminal is formed by at least one plug socket and an electrical contact situated in said plug socket wherein said plug socket is configured to receive a terminal plug of said electrode line.
