Abstract

An assembly for identifying a power injectable vascular access port, including a vascular access port and an identification feature. The port is structured for power injection and includes a housing and a septum together defining a reservoir. A radiographic feature incorporated into the port is perceivable via x-ray following subcutaneous implantation, the radiographic feature identifying the port as suitable for flowing fluid at a fluid flow rate of at least 1 mL/sec therethrough. A structural feature of the port is perceivable via palpation following subcutaneous implantation, the structural feature identifying the port as suitable for accommodating a pressure within the reservoir of at least 35 psi. The identification feature is separated from the port and confirms that the port is both suitable for flowing fluid at a rate of at least 1 mL/sec therethrough and suitable for accommodating a pressure within the reservoir of at least 35 psi.

Claims

1. A method of power injecting a fluid through an access port, comprising:

providing a power-injectable access port suitable for injecting contrast media therethrough at a rate of at least 1 milliliter per second, the power-injectable access port including;

a housing;

a septum;

a reservoir; and

an outlet stem in fluid communication with the reservoir, the power-injectable access port structured for accommodating a pressure developed within the reservoir of at least 35 psi;

attaching a catheter to the outlet stem;

implanting the power-injectable access port and the catheter into a patient;

inserting a distal end of a needle through the septum and into the reservoir; and

injecting contrast media through the needle at a rate of at least one milliliter per second.

2. The method according to claim 1, wherein the step of injecting contrast media through the needle includes inducing a pressure within the reservoir in a range of about 37 psi to about 65 psi.

3. The method according to claim 1, wherein the needle is constructed to have a burst pressure of at least 100 psi.

4. The method according to claim 3, wherein the needle is constructed to have a burst pressure of at least 400 psi.

5. The method according to claim 1, wherein the power-injectable access port is suitable for injecting contrast media therethrough at a rate of between 2 milliliters per second and 5 milliliters per second.

6. The method according to claim 1, further comprising providing an identification feature separate from the power-injectable access port comprising visually perceptible information provided on an element selected from the group consisting essentially of a key chain, a bracelet, a wrist band, a sticker provided on a patient'"'"'s chart, a patient ID card, a label provided on packaging of the access port, and combinations thereof.

7. The method according to claim 1, further comprising consulting an identification feature separate from the power-injectable access port prior to the inserting step, the identification feature comprising visually perceptible information provided on an element selected from the group consisting essentially of a key chain, a bracelet, a wrist band, a sticker provided on a patient'"'"'s chart, a patient ID card, a label provided on packaging of the access port, and combinations thereof.

8. A method of power injecting a fluid through a power-injectable access port, comprising:

inserting a distal end of a needle through a septum and into a reservoir of a power-injectable access port suitable for injecting contrast media therethrough at a rate of at least 1 milliliter per second, the power-injectable access port structured for accommodating a pressure developed within the reservoir of at least 35 psi, the power-injectable access port including an outlet stem in fluid communication with the reservoir, the outlet stem attached to a catheter implanted into a patient along with the power-injectable access port; and

injecting contrast media through the needle at a rate of at least one milliliter per second.

9. The method according to claim 8, wherein the step of injecting contrast media through the needle includes inducing a pressure within the reservoir in a range of about 37 psi to about 65 psi.

10. The method according to claim 8, wherein the needle is constructed to have a burst pressure of at least 100 psi.

11. The method according to claim 10, wherein the needle is constructed to have a burst pressure of at least 400 psi.

12. The method according to claim 8, wherein the power-injectable access port is suitable for injecting contrast media therethrough at a rate of between 2 milliliters per second and 5 milliliters per second.
