  • Publication number: 20150190255
    Abstract: An endoprosthesis for deployment within a body passage includes a framework and a metallic film, which can circumferentially surround the framework or be surrounded by the framework. The framework and metallic film can be attached without using a third material, e.g., without sewing. The framework can define a circumferential recess along at least a portion of its length and circumference. The recess accommodates at least a portion of the metallic film therein.

  • Patent number: 8632580
    Abstract: Medical devices, such as endoprostheses, and methods of making the devices are disclosed. The medical device can include a stent body and a cover including a deposited metallic film. The medical device can be delivered using a delivery device along a tortuous body passage to a treatment site without damaging the medical device, delivery device, or the body passage. In some cases, the stent body is a flexible helical stent body, which may be threaded through one or more fenestrations of the cover. The cover may include longitudinally extending slits or seams, which help the cover to pass through small radii passages without buckling.

  • Patent number: 7169177
    Abstract: A bifurcated stent comprises a body portion, a first branch portion, a second branch portion, a first pivot portion and a second pivot portion constructed from a common continuous sheet of stent material. The body portion, first branch portion and second branch portion provided with a substantially tubular shape, the tubular shape of each defines a lumen respectively therethrough. The lumen defined by the body portion is in fluid communication with the lumen defined by the first branch portion and the second branch portion. The first branch portion is pivotally engaged to an end of the body portion by the first pivot portion. The second branch portion is pivotally engaged to an end of the body portion by the second pivot portion.

  • Patent number: 7097620
    Abstract: A guide wire having pressure sensing capabilities for measuring the pressure of liquid in a vessel comprising a flexible elongate member and having proximal and distal extremities and having an outside diameter of 0.018? or less. The distal extremity of said flexible elongate member is adapted to be disposed in the liquid in said vessel. A housing is carried by the flexible elongate member and has a diameter substantially the same as the diameter of the flexible elongate member. The housing has a space therein with a pressure sensor mounted in the space in the housing. The pressure sensor has a diaphragm that is sensitive to changes of pressure in the liquid in the vessel. The diaphragm is rectangular in shape and is bordered by a rim surrounding the well. A backing plate is formed of an insulating material bonded to the crystal and serves to reinforce the rim of the crystal of semiconductor material.
