A SLIDE MECHANISM (26, 27, 28) IS PROVIDED ALONG THE EXTERIOR SURFACE OF THE INSERTION TOOL TO DRIVE THE CARTRIDGE ASSEMBLY WHICH APPLIES TENSION TO THE ELASTOMERIC BAND, INCREASING THE OPENING DIAMETER SECURING THE SHUNT (10) AND ALLOWING GENTLE RELEASE OF THE SHUNT WHEN DESIRED. ALTERNATIVE EMBODIMENTS OF THE INSERTION TOOL UTILIZE SEVERABLE FIBERS, A TRANSPARENT SPLIT-MYLAR SHEET OR DIAPHRAGM (132), A CANTILEVER FORK (138), A COLLET ASSEMBLY (140) OR AN ELASTOMERIC GRIP COLLET TO GENTLY HOLD AND RELEASE THE SHUNT DURING INSERTION.
