Abstract:
A method for power injection of fluids through an access port includes implanting the access port in a patient, palpating the access port, imaging the access port, and introducing contrast media into the patient through the access port at a rate in a range from about two milliliters per second to about five milliliters per second. The access port may include a housing, a first septum, a second septum, and a radiographic indicator. The first septum and the second septum may respectively cover a first reservoir and a second reservoir of the access port. The first septum may include a first sub-pattern of protrusions and the second septum may include a second sub-pattern of protrusions. The radiographic indicator may include a first portion including information pertaining to the first sub-pattern, and a second portion including information pertaining to the second sub-pattern. The imaging identifies the radiographic indicator.
