Patent ID: 8678843

Claim:
A connector ( 10 ) for a generator of an active implantable medical device, comprising a substantially cylindrical cavity ( 11 ) for receiving a multipolar lead for an active implantable medical device, said cavity comprising a stack ( 200 ) of annular elements ( 210 ) including a first number of annular electrical contacts and a second number of annular isolation elements ( 220 , 320 ), said annular isolation elements being interposed between said annular electrical contacts and isolating said electrical contact elements, wherein: Each isolation element ( 220 , 320 ) comprises: an annular rigid sleeve ( 221 ) having an internal annular side, an internal region, and two lateral sides, and an annular flexible seal ( 222 , 322 ) having two lateral sides and an external annular side disposed against said internal annular side in said internal region of the annual rigid sleeve; Each flexible seal extends axially from one lateral side of the annular rigid sleeve to the other laterial side of the annular rigid sleeve in said interior region of the annular rigid sleeve, each of said lateral sides ( 2225 , 2226 ) of the flexible seal projecting with respect to the corresponding lateral sides of the annular rigid sleeve; and The annular rigid sleeve and the flexible seal of an isolation element further comprise respective mating surface profiles defined on a respective inner annular face ( 2211 ) of the annular rigid sleeve and on said external annular side ( 2221 ) of the flexible seal, thereby immobilising the flexible seal relatively to the annular rigid sleeve in an axial direction.
