The Hepatic Infusion Pump is surgically implanted into the abdomen and a catheter is inserted into a vein/artery (I always mix them up) that leads directly to the tumor. After 3 embolizations we finally got my pump to work. It is used when the cancer is still contained to a single tumor, as far as I can tell, because it feeds the FUDR chemo directly into the tumor with very little side effects. I am still receiving systemic chemo, although it is only Gemzar now, as it was discovered that my lymph nodes were also affected. That, and the fact that it took 4 months to get the pump and my body to cooperate.
It is not widely used, nor is it often a good option, especially if the cancer has spread.
My oncologist is Dr. Nancy Kemeny, the oncologist who perfected the Codman Pump, the one that is implanted in me. There are 1 or 2 other brands that are used in various clinics, but they aren't common.
I hope this answered your questions? I do have a thread called "Liver Infusion Pump?" if you want to read more.
