摘要：
A stent delivery system includes 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 is positioned on the stent receiving portion of the elongate shaft, the stent having a first configuration and a second configuration. A sheath is positioned longitudinally around the inner elongate shaft, the inner elongate shaft extending coaxially at least partially within the lumen of the outer sheath, the outer sheath moveably positionable relative to the outer elongate shaft. 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. A handle assembly is connected to the proximal constraining arrangement, the distal constraining arrangement, and the outer sheath. A brake assembly is positioned within the handle assembly.
