    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.

    摘要： A device for sealing puncture wounds in blood vessels is open at one end and closed at the other end. The tube closure is generally flat and pivotable, and the tube region near the closed end is expandable. The device is initially contained in a sleeve, which is inserted through a cannula, so that the closed end is within the vessel to be sealed. After the cannula is removed, the closure is pivoted and the device withdrawn to a point where the closure abuts the puncture wound. After the sleeve is removed, the expandable region is expanded, so that the blood vessel wall around the puncture is sandwiched between the closure and the expanded region. The device prevents blood from seeping out of the punctured vessel during the healing process.

    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.
