A system for delivering a vaso-occlusive device, comprising: a catheter, a delivery assembly configured to pass within a catheter, comprising a delivery tube having proximal and distal ends, an intermediate spring coil secured to said distal end of the delivery tube,and a gripper assembly secured to a distal coil portion of the intermediate spring coil, wherein the gripper assembly comprises a tip wherein the tip comprises two jaws (122, 123), wherein said tip is formed from a shape-memory alloy, wherein the shape-memory alloy is any metal alloy or polymer that when heated or warmed takes a heat treated shape and when cooled takes another shape, wherein the deliver assembly comprises a core wire and ground wire disposed inside the delivery tube and the intermediate spring coil, the wires (116, 118) forming an electrical circuit, wherein the jaws (122, 123) are configured to move to an open position when the tip warms and to move to a close position when the tip cools so as to connect or disconnect said vaso-occlusive device, wherein the jaws are configured to move to the open position when a current is applied by the core and ground wires thereby heating the tip and to move to the closed position after the electrical current is halted, wherein the vaso-oclusive device is a coil assembly comprising an embolic coil formed with a looped proximal end, a curled proximal end or a T-bit, wherein the gripper assembly is configured to hold the coil assembly so as to deploy the embolic coil, wherein the jaws are configured to open at a hinge to the open position, wherein one or more circular recess is disposed in jaws (122, 123) and the one or more recess is configured to capture the looped proximal end, the curled proximal end or the T-bit. a catheter, a delivery assembly configured to pass within a catheter, comprising a delivery tube having proximal and distal ends, an intermediate spring coil secured to said distal end of the delivery tube,and a gripper assembly secured to a distal coil portion of the intermediate spring coil, wherein the gripper assembly comprises a tip wherein the tip comprises two jaws (122, 123), wherein said tip is formed from a
