1. An integrated access port assembly comprising in combination:
- a catheter; and
an access port attached to the catheter, the access port including a reservoir within the port, said catheter being in continuous, unimpeded fluid communication with said reservoir, and multiple sealable entry sites for entry into said reservoir within said port, said multiple entry sites including a first entry site comprising a first self sealing septum, and at least one second entry site comprising a second self sealing septum aligned opposite said catheter and adapted to accept and permit withdrawal of a guidewire or stylet and direct it into said catheter to thereby facilitate placement of the catheter.
