摘要： Implantable tubular devices have a fenestration in a wall of the tubular device and a conductive coil positioned around the fenestration such that the coil is operable to generate a magnetic field when electrical current flows through the coil. The magnetic field can be used to draw a ferrous or magnetically tipped guidewire or other device to and through the fenestration. In the example of a fenestrated endovascular graft, the coil can be used to draw a guidewire out through a fenestration into a branch blood vessel, such that the guidewire can be used to deliver a branch of the graft through the fenestration into the branch vessel. A power source can be contained in a nosecone.

摘要： A covered stent (100A), including a mesh-shaped support structure, and further including a first section (10A) and a second section (20A) connected to a proximal end and/or a distal end of the first section. The first section includes a plurality of first corrugated rings (11A), and a first covering film (12A) which covers surfaces of the first corrugated rings; the second section includes a plurality of second corrugated rings (21A), two adjacent second corrugated rings being fixedly connected to each other; a plurality of windows (201A) are formed between the plurality of second corrugated rings; and the plurality of first corrugated rings and the plurality of second corrugated rings form the support structure. The second section of the covered stent will not block an opening of a branch vessel (400), and thus it is not necessary to reduce the length of the covered stent in a main branch vessel, such that the covered stent has a sufficiently long anchoring area in the main branch vessel so as to ensure that the covered stent has sufficient anchoring force and thus prevent the displacement or endoleak of a distal end of the covered stent, thereby ensuring a good occluding effect.

摘要： Endovascular prostheses used to treat diseased blood vessels, such as arteries, are disclosed. In some embodiments, an endovascular prosthesis is configured to be implanted within a diseased blood vessel adjacent a diseased section. The endovascular prosthesis may include a fenestration tube through which a guidewire extends in a sealed configuration. The fenestration tube can be selectively openable and configured to sealingly receive an expandable endovascular prosthesis that extends into a side branch vessel of the diseased blood vessel.

摘要： A prosthesis for monitoring a characteristic of flow includes a first tubular prosthesis having a lumen and a sensor for detecting the characteristic of flow through the lumen. The sensor may be covered with another tubular prosthesis or by a layer of material in order to insulate the sensor from the fluid flow. A pocket may be formed between the tubular prosthesis and the adjacent layer of material or prosthesis and the sensor may be disposed in the pocket.

摘要： Vascular prosthesis includes a luminal graft component defining a graft fenestration, at least one support disk fenestration, and a moveable disk defining a moveable disk opening, wherein the graft fenestration, the support disk fenestration and the moveable disk opening are all aligned, and the moveable disk is sandwiched between the support disk and the luminal graft component or between two of the support disks. The moveable disk is moveable between the support disk and the luminal graft component. The support disk is fixed to the luminal graft component. The vascular prosthesis is implanted by a method that includes directing the vascular prosthesis to an aneurysm site of a patient, and then implanting a branch prosthesis through the graft fenestration and into an arterial branch, whereby the moveable disk opening moves within the support disk fenestration to properly align the branch prosthesis with the arterial branch.

摘要： Described herein are flexible implantable occluding devices that can, for example, navigate the tortuous vessels of the neurovasculature. The occluding devices can also conform to the shape of the tortuous vessels of the vasculature. In some embodiments, the occluding devices can direct blood flow within a vessel away from an aneurysm or limit blood flow to the aneurysm. Some embodiments describe methods and apparatus for adjusting, along a length of the device, the porosity of the occluding device. In some embodiments, the occluding devices allows adequate blood flow to be provided to adjacent structures such that those structures, whether they are branch vessels or oxygen-demanding tissues, are not deprived of the necessary blood flow.
