Abstract: A seal design provides positive compression to produce a hermetic seal around a feedthrough pin in a hermetically sealed device, including an implantable medical device. One embodiment of the seal design uses a plurality of “micro-flanges” placed along the length of a feedthrough pin, which micro-flanges grabs and compresses the insulator material to form a hermetic seal. Because the seal design produces positive compression of the insulator, the seal is relatively insensitive to changes in temperature and to differences in thermal expansion coefficients (“TCEs”) between the metal feedthrough and the insulator. It is therefore possible to use a wider variety of materials for the insulator and the feedthrough with the described sealing design, while achieving a superior hermetic seal.
