Radiopaque and septum-based indicators for a multi-lumen implantable port
First Claim
1. A method for identifying a position and an orientation of a subcutaneously implanted multi-lumen access port, the multi-lumen access port including a first septum and a second septum coupled to a housing, the method comprising:
- palpating the subcutaneously implanted multi-lumen access port to locate a first sub-pattern of protrusions on the first septum covering a first reservoir;
palpating the subcutaneously implanted multi-lumen access port to locate a second sub-pattern of protrusions different from the first sub-pattern of protrusions on the second septum covering a second reservoir; and
imaging the subcutaneously implanted multi-lumen access port to identify a radiographic indicator included with the subcutaneously implanted multi-lumen access port, the radiographic indicator comprising a first portion and a second portion, wherein the first portion includes information regarding the first sub-pattern, wherein the second portion includes information regarding the second sub-pattern, and wherein the first and second portions together indicate that the subcutaneously implanted multi-lumen access port is suitable for power injection.

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.
