Suture esophageal stent introducer

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, and first, second, and third lumens extending at least partially therethrough, the first and second lumens defined in a wall surface of the other elongate shaft and positioned on opposite sides of the outer elongate shaft, the third lumen centrally disposed and positioned between the first and second lumens, the outer elongate shaft concentric 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 engaged with a first proximal portion of the stent and a 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 engaged with a first distal portion of the stent and a second distal constraining member engaged with a second distal portion of the stent;
• and
• a release wire disposed through the inner elongate shaft and releasably engaged with a portion of the proximal constraining arrangement and the distal constraining arrangement,
• wherein when the stent is in the first position, the distal constraining arrangement applies an axial mechanical force to the stent, wherein the first proximal constraining member is positioned within the first lumen of the outer elongate shaft, the second proximal constraining member is positioned within the second lumen of the outer elongate shaft, and the distal constraining arrangement is positioned within the inner elongate shaft.
