Overmolded access port including anchoring and identification features
First Claim
1. A medical method, comprising:
- obtaining a power-injectable access port, comprising;
a body defining a fluid cavity accessible via a septum;
a continuous annular flange circumscribing the septum at a top section of the body proximal of the fluid cavity, the flange formed from a radiopaque material, the flange including one or more identification features that convey to a user that the power-injectable access port is capable of power injection; and
a compliant outer cover disposed about the body and in contact with the flange;
implanting the power-injectable access port in a patient;
connecting a catheter to the power-injectable access port such that a lumen of the catheter is in fluid communication with the fluid cavity; and
identifying the power-injectable access port as capable of power injection by viewing the one or more identification features.

Abstract
An access port for providing subcutaneous access to a patient is disclosed. In one embodiment, the port includes an internal body defining a fluid cavity that is accessible via a septum. A compliant outer cover including silicone is disposed about at least a portion of the body. A flange is included with the port body and is covered by the outer cover. The flange radially extends about a perimeter of the port body proximate the septum so as to impede penetration of a needle substantially into the outer cover in instances where the needle misses the septum. The flange can further include both an anchoring feature for securing the outer cover to the port body and an identification feature observable via x-ray imaging technology for conveying information indicative of at least one attribute of the access port. The outer cover provides a suitable surface for application of an antimicrobial/antithrombotic coating.
