Patent ID: 7558630

Claim:
An electrode device that is an implantable cardiological electrode device, comprising: an electrode body ( 2 , 15 ) that is oblong and hose-like and made of an insulating material; an electrode ( 1 ) that is rotationally-symmetric, and annular wherein said electrode ( 1 ) is coupled with said electrode body ( 2 , 15 ) and wherein said electrode ( 1 ) comprises an internal thread ( 11 ); an electrical line ( 4 , 5 ), which runs through said electrode body ( 2 , 15 ), having a core ( 6 ) comprising at least one electrically conductive core and insulation ( 7 ) respectively wrapped individually around each of said at least one electrically conductive core ( 6 ); a support sleeve ( 8 , 8 ′) that is rigid and comprises at least one axially parallel longitude slot ( 19 ) that is open on at least one end of said support sleeve ( 8 , 8 ′) and wherein said support sleeve is configured to hold a line section ( 21 ); a cutting zone between said support sleeve ( 8 , 8 ′) and said internal thread ( 11 ) wherein said cutting zone is configured to hold said line section ( 21 ) between said support sleeve ( 8 , 8 ′) and said internal thread ( 11 ) without severing said core ( 6 ) of said line section ( 21 ) to be contacted of said electrical line ( 5 ); wherein said core ( 6 ) is removably connected to said electrode ( 1 ) via the internal thread ( 11 ) to produce an electrical contact and wherein said electrical contact is a contact connection (K) that is purely mechanical between said electrode ( 1 ) and said electrical line ( 5 ), wherein removal of said core ( 6 ) from said electrode ( 1 ) occurs without severing said core ( 6 ) and allows said core ( 6 ) to be reconnected to said electrode ( 1 ) via axial rotation of said electrode ( 1 ) with respect to said support sleeve ( 8 , 8 ′) wherein: said support sleeve ( 8 , 8 ′) in said electrode body ( 2 , 15 ) on which said line section ( 21 ) of said electrical line ( 5 ) to be contacted is wound without said insulation removed from said electrical line ( 5 ) and on which said electrode ( 1 ) is seated while enclosing said line section ( 21 ); and, said cutting zone on an interior of said electrode ( 1 ) configured to break through said insulation ( 7 ) wherein said electrode ( 1 ) is in contact electrically with said core ( 6 ) of said electrical line ( 5 ).
