Abstract

Assemblies for identifying a power injectable vascular access port are described. One assembly includes a vascular access port, a first identifiable feature, a second identifiable feature, and a third identifiable feature. The first identifiable feature is incorporated into the access port and identifies the access port as suitable for flowing fluid at a fluid flow rate of at least 1 milliliter per second through the access port. The second identifiable feature is incorporated into the access port and identifies the access port as suitable for accommodating a pressure within the cavity of at least 35 psi. The third identifiable feature is separated from the access port and confirms that the implanted access port is both suitable for flowing fluid at a rate of at least 1 milliliter per second through the access port and for accommodating a pressure within the cavity of at least 35 psi.

Claims

1. An assembly for identifying a power injectable vascular access port, comprising:

a vascular access port comprising a body defining a cavity, a septum, and an outlet in communication with the cavity;

a first identifiable feature incorporated into the access port perceivable following subcutaneous implantation of the access port, the first feature identifying the access port as suitable for flowing fluid at a fluid flow rate of at least 1 milliliter per second through the access port;

a second identifiable feature incorporated into the access port perceivable following subcutaneous implantation of the access port, the second feature identifying the access port as suitable for accommodating a pressure within the cavity of at least 35 psi, wherein one of the first and second features is a radiographic marker perceivable via x-ray; and

a third identifiable feature separated from the subcutaneously implanted access port, the third feature confirming that the implanted access port is both suitable for flowing fluid at a rate of at least 1 milliliter per second through the access port and for accommodating a pressure within the cavity of at least 35 psi.

2. The assembly according to claim 1, wherein the other of the first and second features is a structural feature of the body or septum of the access port perceivable via palpation.

3. The assembly according to claim 2, wherein the structural feature comprises a body having a particular geometric shape.

4. The assembly according to claim 1, wherein the radiographic marker is a radiographic pattern included in the septum of the access port.
