  • Patent number: 10299950
    Abstract: A stent delivery system is provided that includes an inner elongate shaft with a lumen and an outer elongate shaft with a lumen, where the inner elongate shaft coaxially extends at least partially within the lumen of the outer elongate shaft. The stent delivery system also a pull member movably disposed along the the inner elongate shaft and first and second restraining members removably secured to the pull member. The stent delivery system also includes a self-expanding stent having an expanded configuration and a collapsed configuration, where the first restraining member is secured to a first portion of the self-expanding stent and the second restraining member is secured to a second portion of the self-expanding stent, thereby securing the self-expanding stent about the outer elongate shaft. Movement of the inner and elongate shafts relative to each other in a first direction applies a tension to the first and second restraining members to move the self-expanding stent to the collapsed configuration.

  • Patent number: 9889027
    Abstract: A stent delivery system is provided with an inner elongate shaft having a proximal portion and a distal portion and an outer elongate shaft having a lumen extending at least partially therethrough, wherein the proximal portion of the inner elongate shaft is at least partially movably disposed within the lumen. The system also includes a stent positionable about the inner elongate shaft having collapsed and expanded configurations. The system includes a proximal restraining member removably engaged with the outer elongate shaft and attached the stent, and a distal restraining member removably engaged with the inner elongate shaft and attached to the stent. The system also has a proximal biasing member operatively engaged with a distal portion of the outer elongate shaft, a distal biasing member operatively engaged with the distal portion of the inner elongate shaft, and an outer tube with a lumen movably disposed over the inner elongate shaft.
