(EN) VASCULAR ACCESS INSTRUMENT HAVING A FLUID PERMEABLE STRUCTURE AND RELATED DEVICES
(FR) INSTRUMENT D'ACCÈS VASCULAIRE COMPORTANT UNE STRUCTURE PERMÉABLE AUX FLUIDES, ET DISPOSITIFS ET MÉTHODES ASSOCIÉS
Abstract
(EN)
A delivery device (12) to deliver a guidewire (48) through an intravenous catheter assembly including a housing (50), which includes a distal end (52), a proximal end (54), and a slot (56). The delivery device includes the guidewire (48), which includes a proximal end (58) and a distal end (60). The delivery device includes a guidewire hub (62) disposed within the housing. The guidewire is secured to the guidewire hub, and the guidewire hub is configured to move along the slot to advance the guidewire in a distal direction. The distal end of the guidewire includes a fluid permeable structure (64). For example, the fluid permeable structure may include an elongated core (66) and a coil (68) extending around the elongated core wherein a space between the elongated core and the coil is configured to receive blood in response to the guidewire being inserted into the vasculature.

L'invention concerne un dispositif de distribution pour distribuer un fil-guide à travers un ensemble cathéter intraveineux pouvant comprendre un boîtier, qui peut comprendre une extrémité distale, une extrémité proximale et une fente. Le dispositif d'administration peut comprendre un fil-guide, qui peut comprendre une extrémité proximale et une extrémité distale. Le dispositif d'administration peut comprendre un raccord de fil-guide disposé à l'intérieur du boîtier. Le fil-guide peut être fixé au raccord de fil-guide, et le raccord de fil-guide peut être conçu pour se déplacer le long de la fente pour faire avancer le fil-guide dans une direction distale. L'extrémité distale du fil-guide peut comprendre une structure perméable aux fluides. Par exemple, la structure perméable aux fluides peut comprendre un cœur allongé et une bobine s'étendant autour du noyau allongé. Dans certains modes de réalisation, un espace entre le cœur allongé et la bobine peut être conçu pour recevoir du sang en réponse à l'insertion du fil-guide dans le système vasculaire.
