Title
(EN) COILED VASCULAR ACCESS INSTRUMENT AND RELATED SYSTEMS
(FR) INSTRUMENT D'ACCÈS VASCULAIRE ENROULÉ ET SYSTÈMES ASSOCIÉS
Abstract
(EN) A vascular access instrument configured to be inserted through a vascular access device, such as a catheter assembly. The vascular access instrument includes a wire (42), which is monolithically formed as a single unit. The wire (42) includes a coil portion (44), which includes multiple loops (46) wound around a central coil axis (48). The wire (42) includes a core portion (50) extending through the coil portion (44) and aligned with the central axis (48). The wire (42) includes a bent portion (52) connecting a distal end of the coil portion (44) with a distal end of the core portion (50). The bent portion (52) may be blunt and atraumatic.
(FR) L'invention concerne un instrument d'accès vasculaire configuré pour être inséré dans un dispositif d'accès vasculaire, tel qu'un ensemble cathéter. L'instrument d'accès vasculaire comprend un fil (42), qui est formé de manière monolithique comme une seule unité. Le fil (42) comprend une partie bobine (44), qui comprend de multiples boucles (46) enroulées autour d'un axe central de bobine (48). Le fil (42) comprend une partie noyau (50) s'étendant à travers la partie bobine (44) et alignée avec l'axe central (48). Le fil (42) comprend une partie courbée (52) reliant une extrémité distale de la partie bobine (44) à une extrémité distale de la partie noyau (50). La partie courbée (52) peut être émoussée et atraumatique.
