Implantable access port including a sandwiched radiopaque insert
First Claim
1. An implantable access port, comprising:
- a port body including a base portion and a cap portion that are cooperatively mated to one another;
a fluid cavity defined by at least one of the base portion and the cap portion;
a stem integrally formed with one of the base and cap portions and in fluid communication with the fluid cavity;
a needle-penetrable septum covering an opening of the fluid cavity; and
a radiopaque insert including;
an insert body including a radiopaque material and shaped to be fixedly interposed between the base and cap portions when the base and cap portions are mated, the insert body further defining at least one contoured portion that enables the radiopaque insert to fit about correspondingly shaped features of at least one of the base portion and the cap portion; and
at least one indicium observable via x-ray imaging technology subsequent to subcutaneous implantation of the implantable access port in a patient, the at least one indicium conveying to an observer a predetermined attribute of the access port.

Abstract
An access port for subcutaneous implantation is disclosed. The access port may include a body for capturing a septum for repeatedly inserting a needle therethrough into a cavity defined within the body. The access port may further 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. The subcutaneously implanted access port may be identified in response to perceiving the at least one feature. In one embodiment, an identification feature is included on a molded insert that is sandwiched between base and cap portions of the access port so as to be visible after implantation via x-ray imaging technology.

14. An implantable access port, comprising:
-
a port body including a base portion and a cap portion that are cooperatively mated to one another, the base portion and the cap portion including poly ether ether ketone; a fluid cavity defined by the base portion and the cap portion; a stem integrally formed with the base portion and in fluid communication with the fluid cavity; a needle-penetrable septum covering an opening of the fluid cavity defined by the cap portion; and a radiopaque insert including; an insert body including a bismuth-containing material and shaped to be fixedly interposed between the base and cap portions when the base and cap portions are mated, the insert body further defining at least one contoured portion that enables the radiopaque insert to fit about the stem of the base portion; and at least one indicium observable via x-ray imaging technology subsequent to subcutaneous implantation of the implantable access port in a patient, the at least one indicium conveying to an observer that the implantable access port is power injectable. - View Dependent Claims (15, 16, 17, 18)
