METHOD AND APPARATUS FOR PROVIDING HERMETIC ELECTRICAL FEEDTHROUGH |
摘要 |
A method and apparatus suitable for forming hermetic electrical feedthroughs in a ceramic sheet having a thickness of = 40 mils. More particularly, the method yields an apparatus including a hermetic electrical feedthrough which is both biocompatible and electrochemically stable and suitable for implantation in a patient's body. The method involves: (a) providing an unfired, ceramic sheet having a thickness of = 40 mils and preferably comprising = 99 % aluminium oxide; (b) forming multiple blind holes in said sheet; (c) inserting solid wires, preferably of platinum, in said holes; (d) firing the assembly of sheet and wires to a temperature sufficient to sinter the sheet material but insufficient to melt the wires; and (e) removing sufficient material from the sheet lower surface so that the lower ends of said wires are flush with the finished sheet lower surface. |
