Venous access port assembly and methods of assembly and use
First Claim
1. 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,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.

Abstract
An implantable venous access port for a catheter. The port assembly (100) includes a body (102), a septum (134) for needle insertion, a discharge port (150) having a passageway (154) and to which a catheter proximal end (202) is connected, and a proximal port (170) with a proximal passageway (172,116) that is in line with the discharge port passageway (154). A chamber (118) of the port body (102) fluidly connects the proximal port passageway and the discharge port passageway, and a proximal septum (174) traverses and seals the proximal passageway (172,116). An entry cannula (190) is insertable into the proximal opening and penetrates the proximal septum (174) and extends to the discharge port passageway (154) enabling a guide wire (198) to be inserted therethrough after the port (100) has been connected to the catheter (200), whereafter the entire assembly is implantable into a patient over the guide wire. A method of over-the-wire venous port placement is disclosed, and also a method for assembling the port.

27. A method of assembling a venous access port, comprising the steps of:
-
providing an upper port body portion and a complementary lower port body portion having respective distal and proximal semicylindrical flanges that upon assembly define respective circular distal and proximal flanges; providing a distal cap and a proximal cap having respective proximal and distal openings complementary to the circular distal and proximal flanges; and affixing the distal cap and proximal cap to the circular distal and proximal flanges respectively by being placed thereover.

28. A method of placing a venous access port into a patient, comprising the steps of:
-
providing a venous port assembly having at least a proximal port passageway, a distal port passageway and at least one chamber in fluid communication with the proximal port passageway and the distal port passageway; connecting a catheter proximal end to the venous port assembly in fluid connection with the distal port passageway; inserting a guide wire through the proximal port passageway, through the at least one chamber, through the distal port passageway, through the catheter and into vasculature of a patient; and placing the venous port assembly and catheter connected thereto into a patient over the guide wire. - View Dependent Claims (29, 30)
