A portal assembly includes a port with at least one resealable septum, and a tube extending from the port with the tube being sized to be received inside a catheter, an angled surface surrounding the tube wherein the angled surface diverges away from the tube in a direction away from the port, and sleeve structure for forcing the end of the catheter into the angled surface, thereby forcing the end of the catheter radially inwardly toward the tube and forming a thickened portion adjacent the end of the catheter to seal and hold the catheter. In a dual port construction, the outlet tubes are parallel to one another at their distal ends, and the sleeve structure forces the end of the catheter into the angled surface, thereby forcing the end of the catheter radially inwardly toward the tubes and forming a thickened portion adjacent the end of the catheter to seal and hold the catheter and to prevent cross-talk between lumens of a dual lumen catheter.
Porte de perfusion comportant un orifice muni d'au moins un septum retirable et un tube s'étendant à partir de l'orifice et dimensionné pour recevoir un cathéter intérieur, une surface inclinée entourant le tube et s'éloignant à la fois du tube et de l'orifice et un manchon permettant d'amener l'extrémité du cathéter sur la surface inclinée et à le centrer dans le tube de façon à constituer une portion épaissie touchant l'extrémité du cathéter qui se trouve ainsi obturé et maintenu. Dans sa variante à deux orifices, les tubes de sortie sont parallèles à leur extrémité distale et le manchon amène l'extrémité du cathéter dans le tube et l'y centre de façon à constituer une portion épaissie touchant l'extrémité du cathéter qui se trouve ainsi obturé et maintenu, et à empêcher toute communication entre les deux lumières du cathéter double.
