Methods of power injecting a fluid through an access port
DCFirst Claim
1. A method of power injecting a fluid through an access port, comprising:
- implanting in a patient an access port suitable for passing fluid therethrough at a rate of at least 1 milliliter per second, the access port including a body defining a cavity, a septum, and an outlet in fluid communication with the cavity, the body and septum structured for accommodating a pressure developed within the cavity of at least 35 psi;
providing an infusion set, comprising;
a non-coring needle having a burst pressure of at least 100 psi;
a polymer tubing in fluid communication with the needle, the tubing formed from a material substantially free of plasticizer, the tubing having a burst pressure of at least 100 psi; and
a connector having an inner surface affixed to an outer surface of the tubing, the connector formed from a material substantially free of plasticizer, the connector having a burst pressure of at least 100 psi; and
flowing a fluid through the infusion set into the access port at a rate of at least 1 milliliter per second.

Abstract
Methods of power injecting a fluid through an access port are described. One method includes implanting in a patient an access port suitable for passing fluid therethrough at a rate of at least about 1 milliliter per second, the access port including a body defining a cavity, a septum, and an outlet in fluid communication with the cavity, and flowing a fluid through an infusion set into the access port at a rate of at least about 1 milliliter per second, the infusion set including a needle in fluid communication with a tubing, the tubing in fluid communication with a connector, each of the needle, tubing, and connector constructed to have a burst pressure of at least about 100 psi.
