Catheter for dilating and destroying vascular stenosis
The patent US12064135B2 describes a specialized catheter designed for the dilation and/or destruction of stenosis in a patient's blood vessels. The catheter features a shaft with a cavity that houses at least one active element, which is fixedly connected to the shaft's wall. This active element is engineered to respond to an axially movable component, enabling the catheter shaft to radially expand. This expansion facilitates the protruding scoring elements on the catheter's exterior to apply pressure on the stenosis. The active element includes a convex bearing surface that interacts with an inclined surface of the movable element, allowing for effective radial expansion during the advancement of the movable component.
Further details of the catheter include the design of the scoring elements, which may have an elongated configuration and can feature a helical structure, potentially in a double helix form. The scoring elements are designed with varying widths, being narrower at the outer regions compared to their fixation points on the catheter shaft. The materials used for the catheter shaft include various polymers such as polypropylene and silicone, while the scoring elements may be constructed from nitinol, stainless steel, or polycarbonate. Additionally, the patent outlines a catheter system that incorporates multiple axially movable elements with different radial widths, enhancing the catheter's functionality in treating vascular stenosis.
