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.

Claims

1. A system for delivery of therapeutic and/or diagnostic agents into a living body, comprising

a. a port assembly including

(1) a base having a mounting side,

(2) a port opening away from the mounting side,

(3) a cannula extending from the mounting side and

(4) a resilient barrier with a hole therethrough between the port and the cannula controlling communication between the port and the cannula;

b. an inserter including

(1) a housing having

(a) a bore therethrough,

(b) a stop in the bore;

(2) a latch movably positioned in the bore against the stop;

(3) a port driver slidably mounted in the bore and having

(a) a seat receiving the port assembly and

(b) a cannula insertion member retained by the port driver and extending through the port, the hole in the resilient barrier and the cannula;

(4) a spring operatively between the housing and the port driver, the latch being selectively engageable with the port driver in a first position with the spring in a stressed state and disengaged with the port driver in a second position.

2. A system for delivery of therapeutic and/or diagnostic agents into a living body, comprising

a. a port assembly including

(1) a base having a mounting side,

(2) a port opening away from the mounting side,

(3) a cannula extending from the mounting side and

(4) a resilient barrier with a hole therethrough between the port and the cannula controlling communication between the port and the cannula;

b. an inserter including

(1) a housing having

(a) a bore therethrough,

(b) a stop in the bore;

(2) a latch movably positioned in the bore against the stop;

(3) a port driver slidably mounted in the bore and having

(a) a seat receiving the port assembly and

(b) a cannula insertion member retained by the port driver and extending through the port, the hole in the resilient barrier and the cannula;

(4) a spring operatively between the housing and the port driver, the latch being selectively engageable with the port driver in a first position with the spring in a stressed state and disengaged with the port driver in a second position;

c. an access hub including

(1) a connector positionable in the port at the resilient barrier with the port assembly separated from the inserter,

the hole in the resilient barrier being closed with the connector displaced from placement in the port and with the cannula insertion member withdrawn from the port and open with the connector fully positioned in the port.
