ABSTRACT:
A needle assembly for use with a catheter. The needle assembly includes a valve disposed in a first shaft; the valve seals, when closed, fluid flow from a first side of the valve to a second side of the valve. The needle assembly further includes a needle system having a second shaft disposed parallel to the first shaft. The second shaft has a first dimension at a first position on the second shaft and has a second dimension at a second position on the second shaft. The second position corresponds to a position of the valve when the needle system is inserted into the valve such that the second position aligns with the position of the valve. In this manner, the valve is stressed less during storage when the needle system remains inserted through the valve. The valve is typically part of an introducer member which includes the first shaft and a flexible sheath which encloses a portion of the second shaft of the needle system.
