AI Technical Summary
Technical Problem
Current guide wire systems, particularly pigtail guide wires, can cause damage to heart tissue during implantation of replacement heart valve prostheses, potentially leading to serious injuries or death.
Method used
A guide wire design featuring one or more threads with atraumatic distal end regions, such as cages, loops, or coils, that unfold from a sheath to minimize tissue contact and damage, with adjustable stiffness and geometry to suit different procedural needs.
Benefits of technology
The atraumatic guide wire design reduces the risk of heart tissue damage, ensuring safe and effective deployment of replacement heart valve prostheses, particularly in minimally invasive procedures like tricuspid and mitral heart valve replacements.

Abstract
The application relates to a guide wire device comprising or consisting of one or more threads (001), one or more distal end regions or tips, and optionally a sheath (010) entirely or essentially entirely covering the one or more threads, and wherein the one or more threads are movable within a sheath and wherein the one or more threads are characterized by a non-invasive tip or end region at the distal end of the one or more threads.
