Classification: CPC A | IPC A

Claim 4:
5. A medical device system, comprising:
an elongate shaft having a lumen extending from a proximal end of the elongate shaft to a distal end of the elongate shaft;
a proximal release wire extending distally from a proximal end configured to remain outside a body to a distal end and slidably disposed within the lumen of the elongate shaft;
a distal stopper coupled to the distal end of the proximal release wire;
a proximal stopper coupled to the proximal release wire proximal to the distal stopper; and
a distal release wire extending distally from a proximal end to a linear distal end and slidably disposed within the lumen of the elongate shaft, the proximal end of the distal release wire comprising a plurality of windings slidably coupled over a linear portion of the proximal release wire, wherein the distal release wire releasably attaches a medical device to the distal end of the elongate shaft;
wherein proximal movement of the proximal release wire over a first distance moves the proximal release wire independent of the distal release wire and proximal movement of the proximal release wire over a second distance greater than the first distance is configured to move the distal release wire in concert with the proximal release wire to detach the medical device from the distal end of the elongate shaft.
