Overmolded access port including anchoring and identification features
First Claim
1. A method for manufacturing an access port for providing subcutaneous access to a patient, the method comprising:
- forming a port body defining a fluid cavity to be accessible via a septum coupled to the port body, the forming including bonding a cap to a base, the septum captured between the cap and the base, the cap including a first keyed feature;
forming a flange including an anchoring feature, the flange including a second keyed feature corresponding to the first keyed feature of the cap;
attaching the flange to the port body proximate the septum, the attaching including aligning the second keyed feature with the first keyed feature; and
covering at least the flange with a compliant outer cover such that the outer cover envelops the anchoring feature included on the flange to anchor the outer cover to the port body.

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.
