Access port identification systems and methods
DCFirst Claim
1. A power injectable port assembly for use with a power injector system, comprising:
- a power injectable port comprising a housing, a septum, a reservoir, and an outlet stem having a lumen in fluid communication with the reservoir, wherein;
the housing comprises;
a first side surface from which an outlet stem extends;
a second side surface different from the first side surface, the second side surface having a concave portion extending along a vertical axis of the power injectable port, at least a portion of the concave portion positioned at the same location along the vertical axis as at least a portion of the reservoir; and
a bottom surface bounded by a bottom perimeter including a concave portion coextensive with the second side surface concave portion;
the power injectable port is adapted to be pressurized by mechanical assistance; and
the power injectable port is adapted to be injected with contrast media at a desired flow rate.

Abstract
An access port for subcutaneous implantation is disclosed. Such an access port may comprise a body for capturing a septum for repeatedly inserting a needle therethrough into a cavity defined within the body. Further, the access port may include at least one feature structured and configured for identification of the access port subsequent to subcutaneous implantation. Methods of identifying a subcutaneously implanted access port are also disclosed. For example, a subcutaneously implanted access port may be provided and at least one feature of the subcutaneously implanted access port may be perceived. Further, the subcutaneously implanted access port may be identified in response to perceiving the at least one feature.
