    Abstract: The present disclosure relates to stents and methods of delivering and deploying the same. The stents include fasteners about their periphery and when the stent is radially compressed, the fasteners come into alignment such that a device may be placed through openings in the fasteners to hold the stent in the radially compressed configuration. When the device is removed from the openings, the stent may expand.

    Abstract: 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 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.

    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.

    Abstract: A prosthesis and a method of controlling flow through a bodily lumen are provided. The prosthesis includes a body having a proximal portion, a distal portion and a lumen extending therethrough. The prosthesis also includes a first valve and a second valve operably connected to the body. The first valve has a proximal portion, a distal portion, a distal end extending distally relative to the proximal portion of the body and a lumen extending through the first valve. The first valve is closed in the absence of a second and third pressure that are greater than a first pressure. The second valve has a proximal portion, a distal portion, a distal end extending distally relative to a proximal portion of the body and a lumen extending through the second valve, the distal end of the first valve extending distal to the distal end of the second valve.
