Claim:
A method of centering at least one valve within a valve seat of a medical device, comprising the steps of: positioning at least one valve within the valve seat of the medical device such that each of the at least one valve is transversely oriented within the valve seat with a diameter less than an inner diameter of the valve seat and a center opening to be aligned with a passageway of the medical device; positioning a cap on the medical device adjacent the valve seat in an initial position wherein an aperture defined by the cap is aligned with the device passageway and the at least one valve adjustably positioned between the device and the cap; positioning a mandrel of a centering tool through the aperture of the cap, through the center opening of the at least one valve and at least partially into the device passageway such that the at least one valve is transversely adjusted to a position within the device wherein the center opening is aligned with the device passageway; affixing the cap to the medical device in a second position such that the at least one valve is axially compressed between the cap and the device such that the at least one valve is fixed in position relative to the valve seat; and withdrawing the centering tool from the device.
