A stent is positioned on the stent receiving portion of the elongate shaft, the stent having a first configuration and a second configuration. A proximal constraining arrangement is engaged with a proximal end of the stent. A distal constraining arrangement is engaged with a distal end of the stent. The stent delivery system includes a handle assembly comprising a first shuttle operably connected to the proximal constraining arrangement and a second shuttle operably connected to the distal constraining arrangement. A brake assembly positioned is within the handle assembly, the proximal constraining arrangement being coupled to a portion of the brake assembly. ## Claims ### Claim 1 A stent delivery system, comprising, an elongate shaft including a proximal portion, a distal portion, at least one lumen extending at least partially therethrough, and a stent receiving portion on the distal portion of the elongate shaft; a stent positioned on the stent receiving portion of the elongate shaft, the stent having a first configuration and a second configuration; a proximal constraining arrangement engaged with a proximal end of the stent, the proximal constraining arrangement comprising a first proximal constraining member having a proximal portion, a second proximal portion, and a distal portion and a second proximal constraining member having a first proximal portion and a distal portion, the distal portion of the first proximal constraining member engaged with a first proximal portion of the stent and the distal portion of the second proximal constraining member engaged with a second proximal portion of the stent; a distal constraining arrangement engaged with a distal end of the stent, the distal constraining arrangement comprising a first distal constraining member having a proximal portion, a second proximal portion and a distal portion, and a second distal constraining member having a proximal portion and a distal portion, the distal portion of the first distal constraining member engaged with a first distal portion of the stent and the distal portion of the second proximal constraining member engaged with a second distal portion of the stent; a handle assembly comprising a first shuttle operably connected to the proximal constraining arrangement and a second shuttle operably connected to the distal constraining arrangement; and, a brake assembly positioned within the handle assembly, the proximal constraining arrangement being coupled to the brake assembly; wherein the proximal constraining arrangement and the distal constraining arrangement applies an axial mechanical force to at least a portion of the stent in the first configuration. ### Claim 2 (depends on 1) The stent delivery system of claim 1, wherein the first proximal constraining member and the second proximal constraining member are interwoven into the proximal end of the stent. ### Claim 3 (depends on 1) The stent delivery system of claim 1, wherein a proximal suture arrangement is disposed at the proximal end of the stent and the first proximal constraining member and the second proximal constraining member are interwoven into the proximal suture arrangement. ### Claim 4 (depends on 1) The stent delivery system of claim 1, wherein the first distal constraining member and the second distal constraining member are interwoven into the distal end of the stent. ### Claim 5 (depends on 1) The stent delivery system of claim 1, wherein a distal suture arrangement is disposed at the distal end of the stent and the first distal constraining member and the second distal constraining member are interwoven into the distal suture arrangement. ### Claim 6 (depends on 1) The stent delivery system of claim 1, wherein the first shuttle and the second shuttle are axially moveable relative to the handle assembly. ### Claim 7 (depends on 1) The stent delivery system of claim 1, wherein the second shuttle is positioned within the first shuttle. ### Claim 8 (depends on 1) The stent delivery system of claim 1, wherein the handle assembly further includes a spring engaged with the second shuttle. ### Claim 9 (depends on 1) The stent delivery system of claim 1, wherein the elongate shaft further comprises a first lumen and a second lumen. ### Claim 10 (depends on 9) The stent delivery system of claim 9, wherein the distal constraining assembly is at least partially disposed in the first lumen. ### Claim 11 (depends on 1) The stent delivery system of claim 1, wherein a release wire is disposed through the elongate shaft and releasably engaged with the proximal constraining arrangement and the distal constraining arrangement. ### Claim 12 (depends on 11) The stent delivery system of claim 11, wherein the stent is in the first configuration upon proximal movement of the first shuttle and the second shuttle from a first position to a second position. ### Claim 13 (depends on 1) The stent delivery system of claim 1, wherein the first shuttle and the second shuttle are axially moveable from a first position and a second position. ### Claim 14 A stent delivery system, comprising, an inner elongate shaft including a proximal portion, a distal portion, at least one lumen extending at least partially therethrough, and a stent receiving portion on the distal portion of the inner elongate shaft; an outer elongate shaft including a proximal portion, a distal portion, at least one lumen extending at least partially therethrough, the inner elongate shaft extending coaxially at least partially within the lumen of the outer elongate shaft, the outer elongate shaft moveably positionable relative to the inner elongate shaft; a stent positioned on the stent receiving portion of the inner elongate shaft, the stent having a first configuration and a second configuration; a proximal constraining arrangement engaged with a proximal end of the stent, the proximal constraining arrangement comprising a first proximal constraining member having a proximal portion, a second proximal portion, and a distal portion, and a second proximal constraining member having a proximal portion and a distal portion, the distal portion of the first proximal constraining member engaged with a first proximal portion of the stent and the distal portion of the second proximal constraining member engaged with a second proximal portion of the stent;
