Title
(EN) TWO-PIECE CATHETERS AND METHODS THEREOF
(FR) CATHÉTERS EN DEUX PARTIES ET MÉTHODES ASSOCIÉES
Abstract
(EN) A two-piece catheter 100 includes a proximal catheter piece 102 and a distal catheter piece 110. The proximal catheter piece includes a proximal catheter-hub piece 104 and one or more extension legs 108. The distal catheter piece 110 includes a distal catheter-hub piece 112 and a catheter tube 114 including one or more catheter- tube lumens. The catheter tube is coupled to the distal catheter-hub piece by a proximal-end portion of the catheter tube. The two-piece catheter has a connected state in which the proximal catheter-hub piece is connected to the distal catheter-hub piece such that the one- or-more catheter-tube lumens are respectively fluidly connected to the one-or-more extension-leg lumens across a two-piece catheter hub.
(FR) La présente invention concerne un cathéter en deux parties 100 incluant une pièce proximale de cathéter 102 et une pièce distale de cathéter 110. La pièce proximale de cathéter inclut une pièce proximale de raccord de cathéter 104 et une ou plusieurs pattes d'extension 108. La pièce distale de cathéter 110 inclut une pièce distale de raccord de cathéter 112 et un tube de cathéter 114 incluant une ou plusieurs lumières de tube de cathéter. Le tube de cathéter est couplé à la pièce distale de raccord de cathéter par une partie d'extrémité proximale du tube de cathéter. Le cathéter en deux parties a un état connecté dans lequel la pièce proximale de raccord de cathéter est reliée à la pièce distale de raccord de cathéter de sorte que la ou les lumières de tube de cathéter sont respectivement reliées fluidiquement à la ou aux lumières de pattes d'extension à travers un raccord de cathéter en deux parties.
