Abstract
The present invention provides an improved imaging catheter which is pre-filled with a fluid suitable for the transmission of imaging signals. Such a catheter eliminates the need for the user to fill and flush the catheter with fluid prior to its use. A catheter according to the present invention may be stored in a container which itself contains fluid to prevent fluid loss. Some embodiments will include reservoirs to hold a supply of fluid to replace that lost, for example, to evaporation. In some embodiments, these reservoirs will further include means for applying pressure to the fluid contained therein so that new fluid is forced into the catheter to replace any fluid lost.
