ABSTRACT:
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 tube 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.
