Abstract: A medical device consists of a stent having a first surface and a second surface parallel to the first surface; a single expanded polytetrafluoroethylene (ePTFE) layer contacting the first surface of the stent; and an elastomeric layer applied to at least one surface of the stent. In at least one embodiment, the elastomeric layer is silicone. In at least one embodiment, the medical device is manufactured by positioning the ePTFE layer such that a first surface of the ePTFE layer contacts a first surface of the stent to form a stent-ePTFE assembly; and applying an elastomeric solution to the first surface of the ePTFE layer and at least one surface of the stent.

Abstract: Devices and methods for facilitating access to the pancreaticobiliary system are disclosed. In particular, the methods include bending a device having an elongate body with a first lumen, a second lumen, and respective first and second exit openings. The methods include inserting a first guidewire through the first lumen and out of the first exit opening to cannulate a pancreatic duct, and inserting a second guidewire through the second lumen and out of the second exit opening to cannulate a biliary duct.

Abstract: Low polymer stress balloons are made by expanding a tube radially while allowing the ends of the tube to move axially in response to the radial expansion.

Abstract: A mold for a medical device balloon has a cavity adapted to receive a hollow parison expandable therein to form the balloon. The cavity has a cone region and a body region. The cone region is heated to a higher temperature, or the mold wall is formed to deliver applied heat more efficiently to the cone region, relative to the body region of the mold.
