    摘要: The present invention is an occlusion device adapted for implantation into a fluid flow-supporting body lumen. The occlusion device comprises a flexible support structure and a flexible fluid flow-occluding membrane that is positioned concentric with the flexible support structure. The support structure is formed from a plurality of interwoven filaments that form an axially flexible and radially compressible structure that, in its expanded state, engages the lumen. The membrane generally includes a constricted region and constriction means, such as a mechanical seal, for closing the membrane at one end. The membrane is formed from a plurality of filaments, and in one embodiment, the membrane filaments are tightly interbraided with the structure filaments to form the occlusion device. Alternatively, the membrane is separately fabricated of interwoven filaments, and is positioned either within the support structure or without the structure so as to surround the support structure.

    摘要: In at least one embodiment, the invention is directed to an endoluminal device comprising a stent and a sleeve. In one embodiment, the endoluminal device is implanted in a portion of the gastrointestinal tract. In some embodiments, the stent has a first region and a second region where the first and second regions provide different levels of radial force. In one embodiment, the first region is made from a plurality of first wires having a first diameter and the second region is made from a plurality of second wires having a second diameter which is smaller than the first diameter. In other embodiments, the endoluminal device has at least one engagement mechanism engaging the stent to the sleeve, the endoluminal device to a body lumen, and any combination thereof. In at least one embodiment, the endoluminal device has a wall with at least one opening therein.

    摘要: The present invention is a visualization system including a small gauge vision catheter that is designed to be stand-alone or received within an instrument channel of a larger endoscope. The vision catheter has imaging means disposable within an imaging channel, a working channel, and an electromagnetic sensor element insertable into the working channel of the catheter to provide position tracking. The working channel of the catheter also provides access for therapeutic and diagnostic tools.

    摘要: The invention relates to an implantable radiopaque stent adapted to be disposed in a body lumen. In one aspect of the invention, at least one radiopaque filament is arranged for permanent attachment to a hollow tubular structure. The filament is desirably arranged in a linear direction traverse to a longitudinal length of the structure, the structure having a tubular wall that defines an inner surface and an outer surface and opposing first open end and second open end. The radiopaque filament improves external imaging of the tubular structure on fluoroscope or x-ray imaging equipment.

    摘要: An endoprosthesis includes a structure which is self-expandable from a reduced profile to an expanded profile. The structure has one or more longitudinal portions and a transverse central plane about which the one or more longitudinal portions are symmetric. A removable sheath retains the one or more longitudinal portions in the reduced profile. A release structure is coupled to the sheath for removal thereof from the one or more longitudinal portions to provide the self-expansion thereof to the expanded profile. A method for implanting the endoprosthesis into a body of a patient includes inserting the structure which is covered by the sheath into the body of the patient such that the structure has the reduced profile. The release structure is then actuated for removing the sheath from the one or more longitudinal portions to provide the self-expansion to the expanded profile.

    摘要: A delivery handle and assembly are provided which allow for deployment and reconstrainment of a stent. The delivery assembly may include a catheter having a lumen extending therethrough; and, a housing having an aperture, the catheter extending through the aperture. A driver is movably coupled to the housing such that the driver can selectively move in different first and second directions relative to the housing. The driver is disposed to engage the catheter such that movement of the driver in the first direction causes a distal end of the catheter to move distally, and that movement of the driver in the second direction causes the distal end of the catheter to move proximally.
