Systems and methods for radiographically identifying an access port
A method for manufacturing an implantable access port, including forming a port body. The port body can include a fluid cavity located in a central region, the fluid cavity having a base surface lying in a first plane, and a plurality of recessed sections located in a peripheral region surrounding the central region, the plurality of recessed sections having a depth extending from a bottom surface of the peripheral region through the first plane. The method further includes locating a septum over the fluid cavity, and positioning a radiopaque insert in the plurality of recessed sections.
1. A method for manufacturing an implantable access port, comprising:
forming a port body comprising:
a fluid cavity located in a central region, the fluid cavity having a base surface lying in a first plane; and
a plurality of recessed sections located in a peripheral region surrounding the central region, the plurality of recessed sections having a depth extending from a bottom surface of the peripheral region through the first plane;
locating a septum over the fluid cavity; and
positioning a radiopaque insert in the plurality of recessed sections.
2. The method for manufacturing according to claim 1 , wherein the radiopaque insert positioned in the plurality of recessed sections comprises a pattern or an indicia for identification of an aspect or characteristic of the access port.
3. The method for manufacturing according to claim 2 , wherein the radiopaque insert positioned in the plurality of recessed sections further comprises an identification feature that is observable via x-ray imaging technology subsequent to subcutaneous implantation of the access port in a patient, the identification feature identifying the access port as a power-injectable port.
4. The method for manufacturing according to claim 3 , wherein the identification feature of the radiopaque insert positioned in the plurality of recessed sections includes alphanumeric indicia.
5. The method for manufacturing according to claim 4 , wherein the alphanumeric indicia of the radiopaque insert positioned in the plurality of recessed sections includes the letters “C” and “T”.
6. The method for manufacturing according to claim 1 , wherein the radiopaque insert positioned in the plurality of recessed sections comprises an identification feature that is observable via x-ray imaging technology subsequent to subcutaneous implantation of the access port in a patient, the identification feature identifying the access port as a power-injectable port.
7. The method for manufacturing according to claim 6 , wherein the identification feature of the radiopaque insert positioned in the plurality of recessed sections includes alphanumeric indicia.
8. The method for manufacturing according to claim 7 , wherein the alphanumeric indicia of the radiopaque insert positioned in the plurality of recessed sections includes the letters “C” and “T”.
9. The method for manufacturing according to claim 1 , wherein the positioning step comprises injection molding the radiopaque insert in the plurality of recessed sections.
10. The method for manufacturing according to claim 1 , wherein the positioning step comprises aligning a bottom surface of the radiopaque insert to be substantially flush with a bottom surface of the central region.
11. The method for manufacturing according to claim 1 , wherein the positioning step comprises preparing a mixture including a metal oxide.
12. The method for manufacturing according to claim 11 , wherein the mixture includes acetyl resin, and wherein the metal oxide is bismuth trioxide.
13. The method for manufacturing according to claim 12 , wherein the mixture includes about 70 percent by weight acetyl resin and about 30 percent by weight bismuth trioxide.
14. A method of manufacturing a power injectable access port, comprising:
forming a port base including one or more fluid cavities, the one or more fluid cavities having a base surface lying in a first plane;
positioning a port cap over the port base, the port cap including a recessed region in a bottom surface, the recessed region surrounding the one or more fluid cavities and having a depth extending through the first plane, the recessed region defining a pattern or indicia indicating that the power injectable access port is suitable for power injection; and
locating at least one septum over the one or more fluid cavities prior to the positioning step.
