Abstract: An exemplary infusion system for accessing an implanted device is disclosed comprising an insertion assembly, a hub comprising a sealable path configured to receive at least a portion of the insertion assembly, a flexible catheter attached to the hub and configured to receive at least a portion of the insertion assembly, and an extension tube attached to the hub. The hub may comprise a manifold element configured to provide fluid communication between the flexible catheter and the extension tube. The hub may also comprise a septum configured to seal the sealable path upon removal of the insertion assembly from the flexible catheter. The extension tube may also be configured to receive at least a portion of the insertion assembly. Exemplary methods of providing a fluid communication path to an implanted device are also disclosed.

Abstract: A locking luer fitting for connecting fluid lines. In one variation the connection interface includes a male luer connector and a corresponding female luer connector. The female luer connector includes a rotatable collar which engages the male luer connector. In another variation the female luer connector includes a cam configured to prevent inadvertent disconnection of the male luer connector. The locking luer fittings described herein may be implemented in various medical and industrial applications where secured fluid line connection interfaces are desirable.
