Patent ID: 8798772

Claim:
An electrode connection for an electrode catheter, comprising: an electrode; a line for electrical signals configured as a coil having an electrode end connected to the electrode; and a fixation device for the electrode end of the coil on the electrode, wherein the fixation device comprises: an inner sleeve, on which the electrode end of the coil sits; and a squeeze ring, which acts upon the electrode end of the coil, establishing an electrical contact with the electrode and a mechanical clamping of the coil on the inner sleeve via a force acting in a radial direction with respect to a length of the coil, wherein the inner sleeve has an outer cone surface, which widens starting from an end engaging with the coil toward a distal end of the electrode catheter forming an outer cone angle and on which the coil end also sits with a conical widening, and wherein the squeeze ring has an inner cone surface which lessens starting from an end engaging with the coil toward a distal end of the electrode catheter forming an inner cone angle, such that the squeeze ring secures the coil end between the inner and outer cone surfaces, the squeeze ring pushed axially onto the widened coil end, and wherein the squeeze ring is connected mechanically and electrically to the electrode on a side of the squeeze ring facing radially outward.
