Patents Assigned to Johan Willem Pieter Marsman
  • Patent number: 8900216
    Abstract: A guidewire for antegrade guidance of vascular interventions of a lower limb artery via a common femoral artery into a superficial femoral artery of a human patient. When in unloaded condition, the guidewire has, at its distal end, a rounded or floppy tip (4). A curved deflection section (5) is located closely proximal of the tip (4) and extends over an angle of curvature such that the rounded tip (4) is spaced from a continuation of an axis of a section proximally neighboring the curved deflection section (5). The curved deflection section (5) has a flexibility causing the curved deflection section (5) to spring back to substantially its original shape after elastic deformation to a straightened condition. A rotation preventer, a kit and a method for facilitating insertion of a guidewire into the superficial femoral artery are also described.
