A storage and dispensing apparatus for a springy guide wire used in medical procedures includes a coiled tubular portion defined by elongate tubing with a bore for receiving the guide wire. A ring section includes a tangential portion of the tubing defining an open end from which the guide wire may be dispensed. Adjacent to the tangential portion, the tubing defines a pair of spaced apart openings from which the guide wire respectively exits and reenters the tubing. Intermediate the pair of openings the tubing defines a curved external surface across which the guide wire runs externally of the tubing and is manually accessible for advancing and retracting movements impelled by a user's thumb, for example. The guide wire defines a pair of gentle S-shaped bends adjacent to the ends of the externally-exposed curved section, which bends cause the guide wire to engage sufficiently with the storage and dispensing apparatus to resist self-ejection.

Un dispositif de rangement et de distribution pour guides métalliques utilisés dans les interventions médicales comprend une partie tubulaire enroulée, définie par un tube allongé présentant un orifice destiné à recevoir le guide. Une section annulaire présente une partie tangentielle du tube qui définit une extrémité ouverte permettant la distribution des guides. Le tube définit une paire d'orifices distincts adjacents à la partie tangentielle, par lesquels le guide entre et sort. Entre la paire d'orifices, le tube définit une surface externe courbe que le guide suit par l'extérieur et qui est accessible manuellement aux mouvements d'avancée et de recul impulsés par le pouce de l'utilisateur, par exemple. Le guide métallique définit une paire de courbures en S peu marquées adjacentes aux extrémités de la section courbe externe, par lesquelles le guide entre suffisamment en contact avec le dispositif de rangement et de distribution pour ne pas être éjecté spontanément.
