  • 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: 8685079
    Abstract: A stent may comprise a plurality of serpentine bands and connectors. A first connector may overlap a second connector when the stent is unexpanded. The first connector may also overlap the second connector in an unexpanded state when the stent is subject to compressive forces in the local area of the connectors, such as when the connectors are located on the inside of a curve. The second connector may be shaped according to a rotation of the first connector about the centroid of the cell between the first connector and the second connector.

  • 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.

  • Publication number: 20100222864
    Abstract: A stent designed for catheter delivery to a target neurovascular site via a tortuous path, in a contracted state, and deployment at the target site, in an expanded state, is disclosed. The stent includes a plurality of expandable tubular members, where member is composed of a continuous wire element forming a plurality of wave segments, and segment contains a pair of opposite looped peaks having a wave shape such that the distance between adjacent sides of a wave, on proceeding from a peak toward opposite peaks, increases monotonically with an inflection point therebetween. The expandable tubular members are joined through adjacent peaks by axial connectors. Radial expansion of the stent from a contracted to expanded state is accommodated by movement of adjacent wave-segment peaks away from one another, without significant change in the axial dimension of the stent. Also disclosed are a system incorporating the stent, and a method of treating a neurovascular abnormality.

  • Patent number: 7294137
    Abstract: A device and method for permitting multi-modal treatment of vascular lesions are disclosed. The device includes an outer delivery catheter, an inner delivery catheter, and a guidewire. The catheter is designed to pass through the inner lumen of the outer delivery catheter, and the guidewire is designed to pass through the inner lumen of the inner delivery catheter. A stent may be loaded inside the outer delivery catheter, with the distal tip of the inner delivery catheter abutting against the proximal end of the self-expanding stent, for pushing the stent distally through the outer delivery catheter.

  • Publication number: 20060142838
    Abstract: A method of handling an endoprosthesis includes providing an endoprosthesis having a deposited metal film with a thickness of about 50 microns or less and reducing the diameter of the endoprosthesis by sequentially collapsing different portions of the prosthesis. The collapsed endoprosthesis can be positioned with a lumen of an endoprosthesis delivery device. Different portions of the endoprosthesis can be sequentially and radially collapsed. For example, the endoprosthesis can be disposed within a hollow form of varying diameter.
