A valved sheath introducer for venous cannulation, including a valve, sheath, handle and cap. The valve is configured to permit safe introduction and removal of medical instruments through the sheath introducer. The valve may have one or more anchoring members and a thickened central portion through which a slit is formed. The central portion may have one or more concave surfaces and the slit can be angled with respect to the top surface of the valve. The cap is attached to the handle, compressing a portion of the valve therebetween.

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.

Infusion apparatuses and methods of use

A reinforced multi-lumen catheter and method of manufacturing the same. An assembly for manufacturing the multi-lumen catheter includes a proximal catheter body substrate including a septum, a first and second distal catheter body substrate, a first and second mandrel, a reinforcing element and a sleeve. The reinforcing element is positioned over the proximal catheter body substrate and at least a proximal region of the first and second distal catheter body substrates.

A reinforced multi-lumen catheter and method of manufacturing the same. An assembly for manufacturing the multi-lumen catheter includes a catheter body substrate including a septum, one or more mandrels, a reinforcing element and one or more sleeves. The septum may have a distal region with a cross-sectional thickness greater than that of a proximal region. The septum can be separately formed. The septum can be split along a length of the distal region. The reinforcing element can be positioned over at least a proximal region of the catheter body substrate.
