APPARATUS AND METHOD FOR DELIVERY OF THERAPEUTIC AND/OR DIAGNOSTIC AGENTS
First Claim
1. A system for delivery of therapeutic and/or diagnostic agents into a living body comprising a port assembly including a base having a mounting side, a port opening away from the mounting side, a cannula extending from the mounting side and a resilient barrier between the port and the cannula controlling communication between the port and the cannula;
- an access hub including a connector positionable in the port at the resilient barrier, a fitting and a passage extending in the access hub through the fitting and the connector, the resilient barrier being open with the connector positioned in the port, the resilient barrier being in sealing contact with the connector about the passage with the connector positioned fully into the port.

Abstract
A system for delivery of therapeutic and/or diagnostic agents into a living body includes a port assembly having a cannula extending from the mounting side, a port opening away from the mounting side and a resilient barrier between the port and the cannula. An access hub includes a connector positionable at the port for opening the resilient barrier. The access hub is movable in the port assembly, is engaged therewith through a resilient ring coupling and forms a seal with the resilient barrier, reducing the amount of volume to be primed. Inserters, both disposable and reusable, include the cannula insertion member as part of the assembly. A spring loaded port driver is operatively mounted within the housing with movement controlled by a latch. The driver includes a seat for receipt of a port assembly. The cannula insertion member is nonremovably fixed in a socket in the port driver in the disposable assembly. In the reusable inserter, the cannula insertion member is slidably mounted within a socket associated with the latch. Slidable movement is limited by locking shoulders. The socket is split and may be splayed to release the cannula insertion member following use.
