Catheter connector
First Claim
1. A connector for a catheter comprising:
- a base arrangement including;
a tube extending from the base arrangement and terminating at an end, the tube sized to be received inside the catheter; and
a concavely shaped surface surrounding the tube, the concavely shaped surface diverging away from the tube in a direction away from the base arrangement, the concavely shaped surface sized to engage an end of the catheter; and
a sleeve arrangement mounted to the base arrangement and engageable with the catheter, the sleeve arrangement defining an inside diameter smaller than an outside diameter of the end of the catheter when the end of the catheter is positioned on the end of the tube.

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.

11. A connector for a catheter comprising:
-
a base arrangement including; a tube extending from the base arrangement and terminating at an end, the tube sized to be received inside the catheter; a surface surrounding the tube positioned to engage an end of the catheter; and a bayonet extending from the base arrangement; and a sleeve arrangement engageable with the catheter, the sleeve arrangement defining an inside diameter smaller than an outside diameter of the end of the catheter when the end of the catheter is positioned on the end of the tube, the sleeve arrangement including a cam slot for receiving the bayonet, the cam slot including an angled portion, the cam slot including an overcenter portion. - View Dependent Claims (12)
