Assignee: BOSTON SCIENTIFIC SCIMED, INC.
Field: Medical technology (Instruments)
Classification: CPC A | IPC A

Claim 0:
1. 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 including a distal stopper, the distal stopper having a greater cross-sectional dimension than an intermediate region of the proximal release wire and slidably disposed within the lumen of the elongate shaft; and
a distal release wire extending distally from a proximal end including a helical coil to a linear distal end and slidably disposed within the lumen of the elongate shaft, the helical coil of the distal release wire slidably disposed over the intermediate region 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.
