1. A needleless valve system comprising:
a cannula comprising a cannula tip, a central lumen, and a radially extending opening in fluid communication with the central lumen; a resiliently compressible valve comprising a valve tip, wherein said valve is disposed around said cannula and a protrusion of the valve is received radially within the radially extending opening, and a housing comprising a housing tip, wherein said cannula tip, said valve tip, and said housing tip comprise a flat surface when said needleless valve system is in a sealed position; wherein when the needleless valve system changes from the sealed position to an open position, the valve deforms and withdraws the protrusion of the valve out of the opening.
