The hearing aid interconnection system comprises an abutment provided with means for being attached to a fixture for anchoring the hearing aid interconnection system to a skull bone. The hearing aid interconnection system comprises means for attaching a hearing aid device to the abutment. The hearing aid interconnection system comprises an extension member attached to the abutment in such a manner that the extension member extends the length of the abutment. ## Claims ### Claim 1 A hearing aid interconnection system comprising an abutment having a fixture end and a hearing aid attachment end, where the fixture end is attachable to a bone integrated fixture thereby anchoring the hearing aid interconnection system to a skull bone, and the hearing aid attachment end of the abutment comprises hearing aid coupling surfaces adapted for engagement with a hearing aid coupling; an extension member attachable to the abutment at the hearing aid attachment end where the extension member further comprises hearing aid coupling surfaces, whereby the extension member allows an extension of the length between the fixture and the hearing aid coupling. ### Claim 2 (depends on 1) A hearing aid interconnection system according to claim 1, wherein the extension member is movably mounted to the abutment via a head of a connection screw which passes through a through going hole in the abutment and into the fixture. ### Claim 3 (depends on 1) A hearing aid interconnection system according to claim 1, wherein the hearing aid coupling surfaces of the extension member differs from the hearing aid coupling surfaces of the abutment. ### Claim 4 (depends on 1) A hearing aid interconnection system according to claim 1, wherein the hearing aid coupling surfaces of the extension member are functionally identical to the coupling surfaces of the abutment. ### Claim 5 (depends on 1) A hearing aid interconnection system according to claim 1, further comprising a tool grip structure provided in the extension member. ### Claim 6 (depends on 5) A hearing aid interconnection system according to claim 5, wherein the extension member is a one-piece body with the hearing aid coupling surfaces at one part thereof and with abutment connection parts, movably connecting the extension member to the head of connection screw, at another part thereof. ### Claim 7 (depends on 2) A hearing aid interconnection system according claim 2, wherein the extension member comprises a coupling part with hearing aid coupling surfaces and a fixation part movably mounted to the abutment and fixating the coupling part to the abutment via the head of connection screw. ### Claim 8 (depends on 7) A hearing aid interconnection system according to claim 7, further comprising a tool grip structure provided in the movable fixation part of the extension member. ### Claim 9 (depends on 1) A hearing aid interconnection system according to claim 1, wherein the hearing aid coupling surfaces of the extension member are arranged for being detachably gripped by gripping jaws belonging to a hearing aid device. ### Claim 10 (depends on 1) A hearing aid interconnection system according to claim 1, wherein the hearing aid coupling surfaces of the extension member are permanently joined to a hearing aid device output vibration member. ### Claim 11 (depends on 1) A hearing aid interconnection system according to claim 1, wherein the extension member has essentially the same width as the top portion of the abutment. ### Claim 12 (depends on 1) A hearing aid interconnection system according to claim 1, wherein the extension member extends along the longitudinal axis of the abutment and that the extension member comprises an abutment contact surface which sealingly matches a corresponding contact surface of the top portion of the abutment. ### Claim 13 (depends on 1) A hearing aid interconnection system according to claim 1, wherein the extension member extends the abutment with a distance which is at least 1 mm. ### Claim 14 (depends on 1) A hearing aid interconnection system according to claim 1, wherein the extension member comprises a snap fit extension member. ### Claim 15 (depends on 14) A hearing aid interconnection system according to claim 14, wherein the snap fit extension member comprises a side section that is adapted to expand or retract under force and to snap couple with the hearing aid attachment end of the abutment. ### Claim 16 (depends on 2) A hearing aid interconnection system according to claim 2, wherein the hearing aid coupling surfaces of the extension member are arranged for being detachably gripped by gripping jaws belonging to a hearing aid device. ### Claim 17 (depends on 3) A hearing aid interconnection system according to claim 3, wherein the hearing aid coupling surfaces of the extension member are arranged for being detachably gripped by gripping jaws belonging to a hearing aid device. ### Claim 18 (depends on 4) A hearing aid interconnection system according to claim 4, wherein the hearing aid coupling surfaces of the extension member are arranged for being detachably gripped by gripping jaws belonging to a hearing aid device. ### Claim 19 (depends on 5) A hearing aid interconnection system according to claim 5, wherein the hearing aid coupling surfaces of the extension member are arranged for being detachably gripped by gripping jaws belonging to a hearing aid device. ### Claim 20 (depends on 6) A hearing aid interconnection system according to claim 6, wherein the hearing aid coupling surfaces of the extension member are arranged for being detachably gripped by gripping jaws belonging to a hearing aid device.
