  • Patent number: 11730426
    Abstract: Aspects of the disclosure relate to medical catheters, including electrophysiological catheters, comprising a catheter maintaining at least one electrode including a plurality of electrode segments. The catheter can include a plurality of slots in which the electrodes can be secured so that the electrodes are at least partially positioned within a center lumen of the catheter. Methods of manufacturing medical catheters are also disclosed. In various methods of assembling a catheter, a hollow, tubular catheter made of a compliant material having a very small, micro or nano outside diameter is provided. Then, the slots are formed in the catheter and the electrode segments are positioned within the slots.

  • Patent number: 11161165
    Abstract: One aspect relates to a method of producing a sleeve for a ring electrode for electrophysiological and neuro-medical applications from a biocompatible metallic tape. Repetitive structures are punched into the tape and each includes at least one surface that is connected by at least one fin to at least one external strip. The at least one external strip connects the repetitive structures to each other on the margin. A sleeve mold is formed from a multiple of the repetitive structures through multiple reforming steps by a reforming technique. The sleeve mold is punched off the such that the sleeve is formed with a first tube-shaped region with a larger diameter and a second tube-shaped region with a smaller diameter. The first region with the larger diameter has a larger external diameter and internal diameter than the second region with the smaller diameter, and the two regions are connected.

  • Patent number: 10933233
    Abstract: One aspect relates to a production method for a ring electrode, to a ring electrode, and to an electrode system. One method for the ring electrode includes providing an outer element, including an outer tube, providing a first inner element, including a first inner tube having a first core of a sacrificial material, providing a second inner element, including a second core of a sacrificial material, forming a composite tube by arranging the first inner element and the second inner element inside the outer element, the first inner element and the second inner element being arranged off-center with respect to one another, drawing the composite tube in a longitudinal direction of the composite tube, separating a composite tube disk from the composite tube, removing the sacrificial material of the first core, and removing the sacrificial material of the second core in order to obtain a contacting opening in the ring electrode.
