Access port identification systems and methods
DC CAFCFirst Claim
1. An access port for providing subcutaneous access to a patient, comprising:
- a body defining a cavity accessible by inserting a needle through a septum, the body including a plurality of side surfaces and a bottom surface bounded by a bottom perimeter, the bottom surface on a side of the port opposite the septum, the bottom perimeter including a concave portion, the side surfaces including a first side surface through which an outlet stem extends; and
at least one structural feature of the access port identifying the access port subsequent to subcutaneous implantation as a particular type of access port, the at least one structural feature comprising a concave side surface in a second side surface different from the first side surface, the concave side surface extending to the bottom perimeter concave portion.

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.

10. A method of identifying a subcutaneously implanted access port, comprising:
-
palpating a subcutaneously implanted access port, wherein the port comprises a body including a plurality of side surfaces, wherein one of the plurality of side surfaces includes an outlet stem extending therefrom; feeling at least one structural feature of the subcutaneously implanted access port, the at least one structural feature comprising one or more concave side surfaces in side surfaces different from the side surface through which the outlet stem extends, each of said one or more concave side surfaces extending to a concave portion in a bottom perimeter of a bottom surface; and identifying the type of subcutaneously implanted access port through the feeling of the at least one structural feature. - View Dependent Claims (11)
