Title (EN) METHODS AND DEVICES FOR VASCULAR ACCESS
(FR) MÉTHODES ET DISPOSITIFS D'ACCÈS VASCULAIRE
Abstract:
(EN) Methods and devices to facilitate positioning of a catheter into a vessel. Devices include axially concentric assemblies of a piercing needle and a dilator that guides an outer catheter into a vessel, such as a blood vessel. The assemblies described herein can include retraction mechanisms and/or lock mechanisms to control needle positioning during catheterization processes as well as improved valves that prevent leakage of fluid from the proximal end of the devices. The devices and method include the use of novel valves to prevent undesired leakage of fluids through the proximal end of the catheter.
(FR) L'invention concerne des procédés et des dispositifs pour faciliter le positionnement d'un cathéter dans un vaisseau. Des dispositifs comprennent des ensembles axialement concentriques d'une aiguille de perçage et un dilatateur qui guide un cathéter externe dans un vaisseau, tel qu'un vaisseau sanguin. Les ensembles décrits ici peuvent comprendre des mécanismes de rétraction et/ou des mécanismes de verrouillage pour commander le positionnement de l'aiguille pendant des processus de cathétérisation, ainsi que des valves améliorées qui empêchent une fuite de fluide à partir de l'extrémité proximale des dispositifs. Les dispositifs et le procédé comprennent l'utilisation de nouvelles valves pour empêcher une fuite indésirable de fluides à travers l'extrémité proximale du cathéter.
