Abstract
An implantable multi-lumen access port including indicators for ascertaining characteristics of the port is disclosed. In one embodiment, the access port comprises a housing that defines a first reservoir and a second reservoir. A first septum and second septum are respectively coupled with the housing to provide selective access to the first and second reservoirs. Each septum includes a plurality of protrusions defined about a periphery thereof that are palpable after implantation of the port in a patient to determine a relative position of the first septum with respect to the second septum. A radiographically observable indicator is also included on a base of the housing, so as to provide information relating to a characteristic of the dual-lumen port, such as suitability for power injection of fluids. The indicator in one embodiment includes a substantially rigid radiopaque component.
