    摘要: A stent scaffold combined with amniotic tissue provides for a biocompatible stent that has improved biocompatibility and hemocompatibility. The amnion tissue can be variously modified or unmodified form of amnion tissue such as non-cryo amnion tissue, solubilized amnion tissue, amnion tissue fabric, chemically modified amnion tissue, amnion tissue treated with radiation, amnion tissue treated with heat, or a combination thereof. Materials such as polymer, placental tissue, pericardium tissue, small intestine submucosa can be used in combination with the amnion tissue. The amnion tissue can be attached to the inside, the outside, both inside and outside, or complete encapsulation of the stent scaffold. In some embodiments, at least part of the covering or lining comprises a plurality of layers of amnion tissue. The method of making the biocompatible stent and its delivery and deployment are also discussed.

    摘要: A stent deployment device includes a flexible, elongate interior catheter and a retaining structure cooperating with the catheter to support a stent along a distal end support region of the catheter. The stent is supported in a reduced radius delivery state to facilitate delivery to a treatment site in a body lumen, by advancing the device over a previously positioned guidewire. An opening at the distal end of the device receives the guidewire into a guidewire lumen of the interior catheter. A second opening through the catheter wall just proximally of the support region allows passage of the guidewire to the exterior of the catheter, whereby the guidewire is contained within the device only along the distal end region. The retaining structure can include an exterior catheter surrounding the interior catheter and stent, and moveable axially relative to the interior catheter. A portion of the guidewire proximally of the second opening is contained between the catheters, and can be removed from the exterior catheter through a slit running axially along the exterior catheter.

A portion of the guidewire proximally of the second opening is contained between the catheters, and can be removed from the exterior catheter through a slit running axially along the exterior catheter. Alternatively, the stent retainer can include a pair of spaced apart sleeves integral with the interior catheter and frictionally retaining opposite ends of the stent, to maintain the stent in the delivery state. In this case the catheter further supports a dilatation balloon surrounded by the stent. The balloon is expanded to free the stent from the sleeves.
