Overmolded access port including anchoring and identification features
First Claim
1. An access port for providing subcutaneous access to a patient, comprising:
- a body defining a fluid cavity accessible via a septum;
a compliant outer cover disposed about at least a portion of the body; and
a flange independent from the body, the flange attached to the body proximate the septum, the flange including an identification feature observable via x-ray imaging technology, the identification feature conveying information indicative of at least one attribute of the access port.

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.

6. An access port for providing subcutaneous access to a patient, comprising:
-
a body defining a fluid cavity accessible via a septum, the body formed of a first material; a compliant outer cover disposed about at least a portion of the body; and a continuous annular flange attached to the body proximate the septum, the flange formed of a second material different from the first material, the flange and body being independent structures, the flange second material in contact with and covered by the outer cover, the flange impeding penetration of a needle past the flange within the outer cover when the needle is intended for penetration into the septum. - View Dependent Claims (7, 8, 9, 10, 11, 12, 13)

14. An access port for providing subcutaneous access to a patient, comprising:
-
a body including a cap and a base, the body defining a fluid cavity accessible via a septum; a compliant outer cover substantially covering the cap and the base to define an outer surface of the access port; and a flange separate from the body and attached to the cap proximate the septum, the flange including an identification feature observable via x-ray imaging technology, the identification feature conveying information indicative of at least one attribute of the access port. - View Dependent Claims (15, 16, 17, 18, 19, 20)

24. An access port for providing subcutaneous access to a patient, comprising:
-
a body including a base and an attachable cap that cooperate to define a fluid cavity accessible via a septum; and a continuous annular flange formed from a radiopaque material, the flange attached to the cap proximate the septum to impede penetration of a needle distally beyond the flange, the body and the radiopaque material in contact with and substantially covered by a compliant outer cover.
