Abstract:
1. A method of diagnosing fallopian tube patency comprising: inserting a distal end of a catheter within a uterus; coupling a dual-barreled syringe to the catheter, wherein the dual-barreled syringe comprises a first barrel containing a gas, a second barrel containing a liquid, a plunger, and a mixer, and wherein the gas contained in the first barrel and the liquid contained in the second barrel are not mixed when coupling the dual-barreled syringe to the catheter; plunging the gas from the first barrel and the liquid from the second barrel into the mixer to mix the gas and the liquid and create an echogenic contrast agent including microbubbles in the liquid; plunging the echogenic contrast agent from the dual-barreled syringe, through the distal end of the catheter and into the uterus and a pair of fallopian tubes adjacent the uterus; and evaluating the pair of fallopian tubes for patency utilizing a contrast enhanced ultrasonography procedure.
