Venous access port assembly and methods of assembly and use

A venous access port for use with a catheter that is to be inserted intravascularly in a patient, comprising:

• a port assembly having a body, at least one septum for infusion by needle, a discharge port for connection with a catheter proximal end and having at least one passageway therethrough, a proximal port having a passageway therethrough, at least one chamber with which the at least one septum is associated establishing fluid communication with a respective at least one discharge port passageway and with the proximal port passageway, and a proximal port closure traversing the proximal port passageway, and
• an entry cannula insertable into the proximal port and through the proximal port closure, through the at least one chamber and extending partially into the discharge port, facilitating insertion of a guide wire through the venous access port by being inserted into and through the entry cannula and into the at least one discharge port passageway and into the catheter proximal end,
• wherein the proximal port is in line with the discharge port enabling a guide wire to extend linearly through the at least one chamber from the proximal port, through the proximal port closure, through the at least one chamber and into and through the at least one passageway of the discharge port into the catheter,
• whereby the venous access port is adapted to be placed into a patient over the guide wire after connection of the catheter proximal end thereto and insertion of the guide wire therethrough.
