Abstract

In a process for manufacturing a female connector for a pacemaker, a tubular ceramic insert is formed with a longitudinal bore and with two radial holes connecting internal contact surfaces with external contact surfaces. The radial holes are filled with conductive material and the internal and external contact surfaces are metallized. The ceramic insert is covered with a layer of metal except for an area around each of the external contact surfaces.

Claims

1. A process for manufacturing a female connector for a pacemaker, comprising the steps of:

forming a tubular ceramic insert with a longitudinal bore therein, and having internal contact surfaces and external contact surfaces, and with two radial holes connecting said internal contact surfaces with said external contact surfaces;

filling said radial holes with conductive material;

metallizing said internal contact surfaces and said external contact surfaces; and

covering said ceramic insert with a layer of metal except for an area around each of said external contact surfaces.

2. A process as claimed in claim 1 wherein the step of covering said ceramic insert with a layer of metal comprises covering said ceramic insert with a soldering agent, and comprising the additional steps of:

inserting said ceramic insert covered with said soldering agent into a metallic tube; and

soldering said metallic tube to said ceramic insert.

3. A process as claimed in claim 1 wherein the step of covering said ceramic insert with a layer of metal comprises covering said ceramic insert with a brazing agent, and comprising the additional steps of:

inserting said ceramic insert covered with said brazing agent into a metallic tube; and

brazing said metallic tube to said ceramic insert.

4. A female connector for a pacemaker, comprising:

a tubular ceramic insert having a longitudinal bore therein and having internal contact surfaces and external contact surfaces and two radial holes connecting said internal contact surfaces with said external contact surfaces;

conductive material filling said radially disposed holes;

a metallization on said internal and external contact surfaces; and

a layer of metal covering said ceramic insert except for an area around each of said external contact surfaces.

5. A female connector as claimed in claim 4 wherein said layer of metal covering said ceramic insert comprises a soldering agent and said female connector further comprising a metallic tube into which said ceramic insert is inserted, said metal tube being soldered to said ceramic insert.

6. A female connector as claimed in claim 4 wherein said layer of metal covering said ceramic insert comprises a brazing agent and said female connector further comprising a metallic tube into which said ceramic insert is inserted, said metal tube being brazed to said ceramic insert.
