Abstract: 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.

Abstract: A method for forming a balloon provides a preform that encloses an internal space. The preform is pre-heated to a shaping temperature by passing a heated gas or fluid via an inlet of the preform into the internal space. The preform is then shaped the preform into a balloon. A device is configured to heat a preform using heated gas or fluid to decouple heating from the temperature of a shaping tool.

Abstract: A process for fixing an implant to a balloon includes providing, in an interior of a sleeve, a heated balloon having a pressurizable balloon interior and an implant crimped to the balloon. The implant has a supporting structure with a multiplicity of through openings. A negative pressure is applied in the interior of the sleeve and a positive pressure is applied to the balloon interior, so that the balloon is deep-drawn into the openings of the implant, producing a form-locking connection between the balloon and the implant. A configuration for carrying out the process and an apparatus for fixing an implant to a balloon are also provided.

Abstract: A method fixes an implant on a balloon. The balloon, together with an implant, which is crimped onto a balloon surface of the balloon such that the implant by an inner side contacts a contact region of the balloon surface, is provided in the interior of a mold. The balloon interior is acted on by a pressure and the implant is inductively heated so that the contact region over the implant is heated and plastically deformed. The inner side of the implant is embedded in the balloon surface. Additionally, an assembly is produced by the method and an apparatus are provided for carrying out the method.

Abstract: A structure for a catheter sleeve is characterized by a particularly high flexural elasticity. The tubular structure has at least one S-shaped profiled strip which is arranged along the structure in a helix. The at least one S-shaped profiled strip has a U-shaped longitudinal section in the region of each side edge. A respective U-shaped longitudinal section of the profiled strip engages with an opposing, U-shaped longitudinal section of a directly adjoining turn of the helix of the same profiled strip or of a further S-shaped profiled strip adjoining in the helix. The structure may further be used in a corresponding catheter.
