Metallic housing for implant with recesses for eddy current reduction
First Claim
1. An implant for implanting into human tissue, comprising:
- a hermetically sealed, metallic housing for enclosing electronic means inside the housing for a high-frequency, telemetric information transfer between a programming device and the implant, the implant including a head for connecting a stimulation line, wherein the housing comprises a metallic wall including groove-shaped recesses arranged at least on an inside of the metallic wall and which reduce a thickness of the metallic wall so that in a region of the recesses on the housing wall a material thickness does not fall below that which is necessary under operating conditions to ensure that the housing is impermeable to fluids.

Abstract
An implant for implanting into human tissue includes a hermetically sealed, metallic housing for enclosing electronic means inside the housing for a high-frequency, telemetric information transfer between a programming device and the implant. The implant additionally includes a head for connecting a stimulation line. The housing comprises a metallic wall including groove-shaped recesses arranged at least on an inside of the metallic wall and which reduce a thickness of the metallic wall so that in a region of the recesses on the housing wall a material thickness does not fall below that which is necessary under operating conditions to ensure that the housing is impermeable to fluids.

18. An implant for implanting into human tissue, comprising:
a hermetically sealed, metallic housing for enclosing electronic means inside the housing for a high-frequency, telemetric information transfer between a programming device and the implant, the implant including a head for connecting a stimulation line, wherein the housing comprises;
a metallic wall including groove-shaped recesses arranged at least on one of an inside and outside of the metallic wall and which reduce a thickness of the metallic wall so that in a region of the recesses on the housing wall a material thickness does not fall below that which is necessary under operating conditions to ensure that the housing is impermeable to fluids; and
a material filling the recesses to effectively compensate for a mechanical instability caused by the recesses.- View Dependent Claims (19, 20, 21, 22)
