    摘要： A medical device for use in supporting a luminal surface of a human or animal body comprising a catheter, a stent mounted on the distal end of the catheter, the stent comprising a hollow cylindrical first wire segment and a hollow cylindrical second wire segment, and a means on the catheter for releasing the stent in the expanded diameter from the catheter. The first wire segment forms a plurality of spaced-apart first wire segment elements each extending 360 degrees around the hollow cylinder, each of the first wire segment elements having a plurality of extendible portions which permit the first wire segment elements to be expanded from the unexpanded diameter to a second, expanded diameter, the first wire segment proximal end having a straight tail extending proximally and longitudinally therefrom. The second wire segment forming a plurality of spaced-apart second wire segment elements each extending 360 degrees around the hollow cylinder, each of the second wire segment elements having a plurality of extendible portions which permit the second wire segment elements to be expanded from the unexpanded diameter to a second, expanded diameter, the second wire segment distal end having a straight tail extending distally and longitudinally therefrom.

    摘要： A method and apparatus for valving body fluids involving a flexible tubular body with a drainage canal therethrough, including collapsible means for blocking the passageway and thereby preventing the flow of urine. The length of the device is such that one end protrudes into the bladder and the other end terminates interior of the meatus. The device includes a means for anchoring to secure it in place and a plug device for deflating and releasing the anchoring means and for collapsing the blocking means to facilitate removal of the device from the body. The device is manually actuable to an open position and means are provided to delay the closing of the device for a sufficient period of time to allow voiding of the bladder. The collapsible and expandable nature of the device facilitates its insertion and removal, particularly while passing through areas of restricted diameter.

    摘要： The present invention relates to mucoadhesive drug delivery devices and their methods of preparation and use. More specifically the present invention relates to mucoadhesive drug delivery devices comprising one or more biocompatible purified proteins combined with one or more biocompatible solvents and one or more mucoadhesive agents. The mucoadhesive drug delivery devices may also include one or more pharmacologically active agents. The drug delivery devices of the present invention adhere to mucosal tissue, thereby providing a vehicle for delivery of the pharmacologically active agent(s) through such tissue.
