Abstract
An electrode arrangement (10) comprising a first electrode cable (12) which is to be inserted into the coronary sinus and which has an electrode conductor (32) and at least one electrode (38, 40) for outputting and/or receiving electrical signals in the coronary sinus. Longitudinally slidably guidable in the lumen of the first electrode cable (12) at least in a longitudinal portion-wise manner is a second electrode cable (14) which can issue from the first electrode cable through an opening (52) at the distal end thereof and which is adapted for insertion into a cardiac vein which opens into the coronary sinus.
Claims60
An electrode arrangement for insertion into a coronary sinus and a cardiac vein of a user, the coronary vein opening into the coronary sinus, the arrangement comprising:
- an external sheathing having a distal end and a lumen;
- a first electrode cable in the lumen, having an electrode conductor and at least one electrode for outputting and/or receiving electrical signals in the coronary sinus;
- and
- a second electrode cable in the lumen and slidably guidable therein, in at least a longitudinal portion-wise manner, the second electrode cable being able to issue from an opening at the distal end thereof and which is adapted for insertion into the cardiac vein, the second electrode cable tapering towards the distal end.
An electrode arrangement for insertion into a coronary sinus and a cardiac vein of a user, the coronary vein opening into the coronary sinus, the arrangement comprising:
- an external sheathing having a distal end and a lumen;
- a first electrode cable in the lumen, having an electrode conductor of a two-coil nature, wherein two respectively electrically insulated wires extend in each of the two coils of the electrode conductor, and at least one electrode for outputting and/or receiving electrical signals in the coronary sinus;
- and
- a second electrode cable in the lumen and slidably guidable therein, in at least a longitudinal portion-wise manner, the second electrode cable being able to issue from an opening at the distal end thereof and which is adapted for insertion into the cardiac vein.
An electrode arrangement for insertion into a coronary sinus and a cardiac vein of a user, the coronary vein opening into the coronary sinus, the arrangement comprising:
- an external sheathing having a distal end and a lumen;
- a first electrode cable in the lumen, having an electrode conductor and at least one electrode for outputting and/or receiving electrical signals in the coronary sinus;
- and
- a second electrode cable in the lumen and slidably guidable therein, in at least a longitudinal portion-wise manner, the second electrode cable being able to issue from an opening at the distal end thereof and which is adapted for insertion into the cardiac vein;
- wherein the external sheathing has a receiving opening for the second electrode cable, with a clamping device for arresting the axial position of the second electrode cable relative to the external sheathing, the clamping device provided at the receiving opening and having an eccentric screw which extends in the lumen of the external sheathing perpendicularly to the longitudinal axis thereof between the first and the second electrode cables.
