Abstract:
1. A reduced deployment force delivery device for intraluminal devices comprising: an inner tube having a proximal region, a distal region and a distal tip, the distal region configured to receive a self-expanding intraluminal device having proximal and distal ends and a lumen therethrough; a sheath having a proximal end and a distal end, the sheath mounted concentrically around the inner tube; a first outer layer having a proximal end and a distal end, the proximal end of the first outer layer is connected to a the distal end of the sheath; a second outer layer having a proximal end and a distal end, the distal end being connected to the distal tip of the inner tube; and an inner layer having a first end and a second end, the first end being connected to a distal end of the first outer layer at a folded region and configured to pass along a first portion of the outer surface of the self-expanding intraluminal device, wrapping around the proximal end of the self-expanding intraluminal device and passing through the lumen of the entire self-expanding intraluminal device, wrapping around the distal end of the self-expanding intraluminal device and proceeding proximally over a second portion of the outer surface of the self-expanding intraluminal device and connecting to the proximal end of the second outer layer at a folded region, wherein the reduced deployment force device is configured to release the proximal end of the self-expanding intraluminal device while maintaining the distal end of the self expanding intraluminal device in a compressed state under the second outer layer until the sheath is fully retracted.
