Medical implantable device and method for connecting an antenna to the same
First Claim
1. Medical implantable device comprising a hermetically sealed, radio shielded encapsulation, which is adapted to be implanted inside living tissue, and an RF-circuit board positioned inside the encapsulation for communication with an RF-device outside the tissue, the RF-circuit board being connectible to an antenna located outside of the encapsulation, via at least one hermetical feed through in form of at least one conductor passed through a wall portion of the encapsulation in a liquid and gas tight manner and electrically insulated from the encapsulation, the RE-circuit board comprising at least one connector pin which is resilient or resiliently mounted on the RF-circuit board, to cause the connector pin, in a mounted state of the RF-circuit board in the encapsulation, to resiliently engage the conductor and electrically connects the conductor with the RF-circuit board, and a shielding sleeve that surrounds the conductor and protrudes essentially the same distance as the conductor or longer, the shielding sleeve being connected to the RF-circuit board by at least one resilient or resiliently mounted connector pin.

Abstract
In a medical implantable device having a hermetically sealed, radio shielded encapsulations containing an RF circuit therein and having an antenna located outside of the encapsulation, and in a method for connecting the RF circuit to the antenna, at least one hermetical feedthrough connection is provided in the form of at least one conductor passing through a wall portion of the encapsulation in a liquid-tight and gas-tight manner, with the feedthrough being electrically insulated from the encapsulation. At least one connector pin is provided on an RF circuit board, which is resiliently mounted on the RF circuit board. The RF circuit is mounted in the encapsulation so as to cause the connector pin to resiliently engage the conductor and to electrically connect the conductor with the RF circuit board.
