CORONARY GUIDEWIRE

A coronary guidewire (10) includes a flexible elongated core (20) and a coil (40) comprising a plurality of helical coil turns wound around a distal end portion of the core. The coil (40) has a proximal end (50) and an opposite distal end (52). A weld joint (62) connects the distal end (52) of the c...

description A coronary guidewire (10) includes a flexible elongated core (20) and a coil (40) comprising a plurality of helical coil turns wound around a distal end portion of the core. The coil (40) has a proximal end (50) and an opposite distal end (52). A weld joint (62) connects the distal end (52) of the coil to the core (20) and defines a distal tip (80) of the guidewire. The distal end (52) can have a flexible bend radius as small as 0.2mm-0.6mm. L'invention concerne un fil-guide coronaire (10) qui comprend une partie centrale allongée, souple (20) et une bobine (40) comportant une pluralité de tours de bobine hélicoïdale, enroulés autour d'une partie d'extrémité distale de la partie centrale. La bobine (40) possède une extrémité proximale (50) et une extrémité distale opposée (52). Un joint soudé (62) relie l'extrémité distale (52) de la bobine à la partie centrale (20) et définit une pointe distale (80) du fil-guide. L'extrémité distale (52) peut avoir un rayon de courbure souple aussi petit que 0,2 mm à 0,6 mm.
