Assemblies for identifying a power injectable access port
A method of performing a power injection procedure, including taking an x-ray of a subcutaneously implanted access port in a patient to determine whether the access port includes a radiographic feature indicating that the access port is suitable for flowing fluid at a rate of at least about 1 milliliter per second through the access port. The access port defines one or more fluid reservoirs, each fluid reservoir accessible through a cannula-penetrable septum. The method further includes identifying the indicating radiographic feature on the x-ray, and in accordance with the presence of the indicating feature on the x-ray, flowing a fluid through the access port at a rate of at least about 1 milliliter per second.

taking an x-ray of a subcutaneously implanted access port in a patient to determine whether the access port includes a radiographic feature indicating that the access port is suitable for flowing fluid at a rate of at least about 1 milliliter per second through the access port, the access port defining one or more fluid reservoirs, each fluid reservoir accessible through a cannula-penetrable septum;
identifying the indicating radiographic feature on the x-ray; and
in accordance with the presence of the indicating radiographic feature on the x-ray, flowing a fluid through the access port at a rate of at least about 1 milliliter per second.
2. The method according to claim 1 , wherein the identifying step comprises identifying a radiographic pattern included in the cannula-penetrable septum of the access port.
3. The method according to claim 1 , wherein the identifying step comprises identifying a radiographic letter.
4. The method according to claim 1 , further comprising a step of confirming that the access port is suitable for flowing fluid at a rate of at least about 1 milliliter per second by palpating to feel a structural feature of the access port indicating that the access port is suitable for flowing fluid at a rate of at least about 1 milliliter per second through the access port.
5. The method according to claim 1 , further comprising a step of confirming that the access port is suitable for flowing fluid at a rate of at least about 1 milliliter per second by visually perceiving information outside of a body of a patient included on an element selected from the group consisting 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, the element indicating that the access port is suitable for flowing fluid at a rate of at least about 1 milliliter per second through the access port.
6. The method according to claim 1 , further comprising a step of confirming that the access port is suitable for flowing fluid at a rate of at least about 1 milliliter per second by detecting a radiofrequency identification (RFID) tag associated with the implanted access port, the RFID tag signaling that the access port is suitable for flowing fluid at a rate of at least about 1 milliliter per second through the access port.
7. The method according to claim 1 , further comprising a step of confirming that the access port is suitable for flowing fluid at a rate of at least about 1 milliliter per second by detecting an ultrasound-detectable feature associated with the implanted access port, the ultrasound-detectable feature indicating that the access port is suitable for flowing fluid at a rate of at least about 1 milliliter per second through the access port.
8. A method of performing a power injection procedure, comprising:
providing an access port including a cannula-impenetrable housing and a radiographic feature indicating that the access port is suitable for flowing fluid at a rate of at least about 1 milliliter per second through the access port;
implanting the access port in a subcutaneous pocket formed under a patient's skin, resulting in an implanted access port;
taking an image of the implanted access port via imaging technology;
identifying the implanted access port as being suitable for flowing fluid at a rate of at least about 1 milliliter per second through the implanted access port via the image of the radiographic feature of the implanted access port; and
if the image of the implanted access port includes an image of the radiographic feature, injecting contrast media fluid through the implanted access port at a rate of at least about 1 milliliter per second.
9. The method according to claim 8 , wherein the identifying step comprises identifying a radiographic letter.
10. The method according to claim 8 , further comprising a step of confirming that the implanted access port is suitable for flowing fluid at a rate of at least about 1 milliliter per second by palpating to feel a structural feature of the implanted access port indicating that the implanted access port is suitable for flowing fluid at a rate of at least about 1 milliliter per second through the implanted access port.
11. The method according to claim 8 , further comprising a step of confirming that the implanted access port is suitable for flowing fluid at a rate of at least about 1 milliliter per second by visually perceiving information outside of a body of a patient included on an element selected from the group consisting 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, the element indicating that the implanted access port is suitable for flowing fluid at a rate of at least about 1 milliliter per second through the implanted access port.
12. The method according to claim 8 , further comprising a step of confirming that the implanted access port is suitable for flowing fluid at a rate of at least about 1 milliliter per second by detecting an RFID tag associated with the implanted access port, the RFID tag signaling that the implanted access port is suitable for flowing fluid at a rate of at least about 1 milliliter per second through the implanted access port.
13. The method according to claim 8 , further comprising a step of confirming that the implanted access port is suitable for flowing fluid at a rate of at least about 1 milliliter per second by detecting an ultrasound-detectable feature associated with the implanted access port, the ultrasound-detectable feature indicating that the implanted access port is suitable for flowing fluid at a rate of at least about 1 milliliter per second through the implanted access port.
14. A method of performing a power injection procedure, comprising:
implanting an access port including a fluid reservoir accessible through a septum and a radiographic feature, the radiographic feature indicating that the access port is capable of handling pressures associated with power injection, the implanting resulting in an implanted access port;
taking an image of the implanted access port via imaging technology;
if the image of the implanted access port includes a radiographic feature that identifies the implanted access port as capable of handling pressures associated with power injection, inserting a needle through a septum, the needle connected to tubing and in fluid communication therewith, the needle and the tubing structured to accommodate a fluid pressure of at least about 400 psi; and
injecting contrast media fluid through the tubing and the needle to induce a pressure within the implanted access port in a range of about 37 psi to about 65 psi.
