(EN) CATHETER HAVING A DISTAL DRUG DELIVERY UNIT AND METHOD OF USING SAME
(FR) CATHETER PRESENTANT UNE UNITE DISTALE D'ADMINISTRATION DE MEDICAMENTS, ET PROCEDE D'UTILISATION DE CELUI-CI
Abstract
(EN)
A catheter having a drug delivery unit at the distal end thereof. The drug delivery unit includes an actuator capable of assuming an activated and an inactivated configuration. The drag delivery unit also includes a receptacle capable of accepting a therapeutic agent. The actuator and receptacle are in communication with each other such that the actuator transmits force to the receptacle and the receptacle accepts force from the actuator in an activated configuration of the actuator. Also provided is a method of delivering a therapeutic agent to a target site using the catheter of the present invention.
(FR)
L'invention concerne un cathéter présentant, à son extrémité distale, une unité d'administration de médicaments. L'unité d'administration de médicaments comprend un actionneur capable de prendre une configuration activée et inactivée. L'unité d'administration de médicaments comprend également un réceptacle destiné à recevoir un agent thérapeutique. L'actionneur et le réceptacle sont en communication entre eux, de telle sorte que l'actionneur transmette une force au réceptacle, et que le réceptacle reçoive une force de l'actionneur, en une configuration activée de l'actionneur. L'invention concerne en outre un procédé d'administration d'un agent thérapeutique à un site cible au moyen du cathéter selon l'invention.
