A guidewire manufacturing assembly and method of forming an improved distal tip on a guidewire are disclosed. A guidewire may be an elongate shaft (12),a coil (16) disposed along the length of the shaft (12), a holding fixture (20) coupled to the shaft (12), a solder ball (22) disposed 5 to flux (24), and a heat source (26) disposed proximate the solder ball (22) to partially melt the solder ball (22) and allow formation of an atraumatic distal tip.

L'invention concerne un ensemble et un procédé de fabrication de fil-guide servant à former une extrémité distale améliorée sur un fil-guide. Un fil-guide peut être une tige allongée (12) sur la longueur de laquelle est placé un enroulement (16) et à laquelle est couplé un appareil de maintien (20). Selon l'invention, un globule de soudure (22) est couplé à une quantité de fondant (24) et une source de chaleur (26) est placée à proximité du globule de soudure (22) pour faire partiellement fondre le globule de soudure (22), une extrémité distale non traumatique étant ainsi formée.
