A balloon catheter includes a balloon extending in an axial direction (z). The balloon includes an expandable balloon wall that extends around the balloon in a circumferential direction (U) and surrounds a balloon interior space of the balloon. The balloon interior space is configured to be filled with a fluid inflation medium. A capacitive sensor is configured to measure a diameter (D) extending in a radial direction (R) of the balloon. The sensor includes a capacitor having two planar and expandable electrodes arranged on the balloon wall.

Capacitive sensor for precisely measuring high strain on the surface of a balloon of a balloon catheter

A method for producing a balloon for a balloon catheter includes providing the balloon that has an outer surface. A solution including a solvent and a polymer is used to deposit the polymer onto the surface and form a surface coating of the polymer.

Functionalized balloon surface

An arrangement of an expandable substrate and a strain sensor applied onto a surface of the substrate. The strain sensor is made from an ink composition that is a mixture of a conductive silver ink and a conductive carbon ink. A ratio between the conductive silver ink and the conductive carbon ink lies in a range between 30:70 and 70:30 in on arrangement and between 40:60 and 60:40 in another. A method for forming the arrangement directly prints the strain sensor on the substrate.
