Abstract
A sensor connection element of a catheter or an electrode line, which has a plate-like substrate including at least one recess and layer-like electrical conductors with sensor connection faces and/or actuator connection faces on or beneath at least one sensor surface.
Claims15
A sensor connection element of a catheter or an electrode line comprising:
- a plate-like substrate, comprising at least one recess and layer-like electrical conductors with sensor connection faces and/or actuator connection faces on or beneath at least one sensor surface,
- wherein the plate-like substrate is formed of a material that is rigid in compression and has at least one recess in both side edges, said recesses providing the sensor connection element with a predetermined flexural resilience.
A sensor connection element of a catheter or an electrode line comprising:
- a plate-like substrate, comprising at least one recess and layer-like electrical conductors with sensor connection faces and/or actuator connection faces on or beneath at least one sensor surface,
- wherein a conductor lug for providing a sensing and/or stimulation electrode of an electrode line is fitted on at least one actuator connection face.
An electrode line comprising:
- a line body;
- a sensor connection element comprising:
- a plate-like substrate, comprising at least one recess and layer-like electrical conductors with sensor connection faces and/or actuator connection faces on or beneath at least one sensor surface,
- wherein the plate-like substrate is formed of a material that is rigid in compression and has at least one recess in both side edges and in at least one surface, said recesses providing the sensor connection element with a predetermined flexural resilience,
- wherein recesses that are offset relative to one another in the longitudinal direction of the substrate and that extend over the central line are provided in the side edges in such a way that the sensor connection element has a predetermined compressive resilience with respect to forces acting in the longitudinal direction,
- wherein a Fiber Bragg Grating (FBG) sensor is fitted on the plate-like substrate so as to be arranged parallel to the side edges and is connected via the sensor connection faces in such a way that the sensor connection element forms a 3D force sensor, and
- wherein the line body is compressible and flexible in a distal portion, in which the sensor connection element is arranged, in such a way that it does not falsify the response of the 3D force sensor or strain gauge to external forces;
- and
- a sensor provided or connected by means of the sensor connection element and/or a sensing and/or stimulation or ablation electrode provided by means of the sensor connection element.
