  • Publication number: 20260025919
    Abstract: An elongate conductor arrangement for electrical connection to a medical device is proposed, including an elongate sheet substrate and at least two conductor lines. Therein, the elongate sheet substrate comprises a support layer consisting of a LCP material. The conductor lines are arranged along a surface of the sheet substrate. The sheet substrate is twisted around a longitudinal axis of the sheet substrate into a spiral configuration. The conductor arrangement is easily bendable in various directions and allow a simple electrical connection to e.g. a circuitry of a medical device beneficially using LCP technology.

  • Publication number: 20250135195
    Abstract: A paddle lead for implantation in the epidural space through an insertion tool, the paddle lead comprising a paddle structure with a first paddle wing, a second paddle wing and at least one resilient element connected with at least one of the first paddle wing and the second paddle wing, wherein the at least one resilient member biases at least one of the first paddle wing and the second paddle wing to an expanded state. According to an aspect of the invention, the at least one resilient element has a longitudinal extension direction that runs exclusively along the longitudinal extension direction of the paddle structure and in that the at least one resilient element has a wall that surrounds alone or with another part of the paddle structure a hollow space, wherein the hollow space also extends exclusively along the longitudinal extension direction of the paddle structure.

  • Publication number: 20250001190
    Abstract: An implantable medical device for implantation into a patient comprises a body having a distal end and an electrode device for at least one of emitting an electrical stimulation signal and sensing an electrical sense signal, said electrode device being arranged at said distal end of the body and comprising a helix element to be screwed into tissue. A blade section is configured to cut into tissue when said helix element is screwed into tissue.

  • Publication number: 20240371546
    Abstract: In a method for fabricating a medical electrode device for implantation into a patient a sleeve element having an inner lumen is provided, and an electrical supply line is inserted into the lumen of the sleeve element. The sleeve element is deformed to obtain a contact element for the medical electrode device, a portion of the sleeve element forming a contact face of the contact element for electrically contacting tissue, wherein as a result of deforming the sleeve element a crimp connection between the contact element and the electrical supply line is established.
