摘要： An introduction arrangement for a fenestrated or branched stent graft (13) intended for deployment into the lumen of a vessel having a blind vessel extending from it. The introducer (1) has a distal end intended to remain outside a patient in use and a proximal end with a nose cone dilator (11) and an arrangement to retain the branched stent graft distally of the nose cone dilator. A sheath (15) on the introducer extends over the branched stent graft to the nose cone dilator. An indwelling catheter (21) extends from the distal end of the introducer and enters the fenestration or side arm and through to the nose cone dilator, the indwelling catheter has a guide wire (29) extending through it. The guide wire can be extended beyond the nose cone dilator in use before the sheath is withdrawn from the branched stent graft so that it can be snared from the contra-lateral artery.

摘要： An endovascular graft delivery system includes an endovascular prosthetic device and one or more trigger wires deployably engaging portions of the endovascular prosthetic device. An electrical element is positioned at a proximal end of a trigger wire. The electrical element is in signal communication with the trigger wire to communicate operational signals over the trigger wire. The operational signals may be power or control signals to assist with positioning the endovascular prosthetic device at a desired deployment location.

摘要： A delivery system for percutaneously delivering and deploying a stented prosthetic heart valve. The delivery device includes a delivery sheath slidably disposed over an inner shaft, and a capture assembly. The capture assembly includes a spindle and a biasing member. The spindle is attached to the inner shaft and defines slot. The biasing member is disposed within the slot and self-transitions from a deflected condition to a normal condition. In a delivery state, the delivery sheath retains the prosthesis over the inner shaft and coupled to the spindle via the capture slot, including a portion of the prosthetic valve being engaged within the slot and the biasing member forced to the deflected condition. In a deployment state, the delivery sheath is proximally withdrawn and the biasing member self-transitions toward the normal condition to eject the prosthetic valve from the capture slot.

摘要： In a method of accessing and closing a vessel, a vessel is percutaneously accessed through a first opening in the vessel wall at a first location. A stent-graft is delivered through the first opening to a second location. The stent-graft is deployed at the second location. The vessel is then accessed through a second opening through the vessel wall at the second location, wherein the second opening is generally aligned with a fenestration through the graft material of the stent-graft. A delivery device is advanced through the second opening, the fenestration, and the stent-graft lumen to a third location spaced from the first location and the second location. After the delivery device is retracted through the lumen of the stent-graft and out of the fenestration and the second opening, the stent graft is rotated or translated such that the fenestration is not aligned with the second opening.

摘要： A dual lumen catheter may be provided with one or more stents in a stent-deployment lumen and a wire guide disposed through a wire guide lumen. The wire guide may be directed to a target site in a patient body such as a biliary stricture. The catheter may be directed along the wire guide until it is in or adjacent the target site. A distalmost stent may be advanced out a distal side-facing aperture of the stent-deployment lumen into the target site by a pusher member that advances the stent or that holds the stent in place while the catheter is proximally withdrawn from around the stent. With the wire guide remaining substantially in place, the stent-deployment lumen can be reoriented and the steps repeated to place a second (and, if desired, subsequent) stent(s) next to—and generally parallel with—the first stent.

摘要： Catheter including an inner tubular member having a fluid lumen defined therein and an exterior surface. The exterior surface defining a first distal flow port and a second distal flow port. An outer tubular member is movable relative to the inner tubular member in a proximal direction and having an interior surface. A first pressure chamber is defined between the exterior surface and the interior surface, and between a first distal seal assembly and a first proximal seal assembly. A second pressure chamber is defined between the exterior surface and the interior surface, and between a second distal seal assembly and a second proximal seal assembly. Fluid introduced through the fluid lumen pressurizes the first pressure chamber and the second pressure chamber to generate a respective force at the first proximal seal assembly and to the second proximal seal assembly to urge the outer tubular member in the proximal direction.

摘要： Catheter comprising an inner tubular member defining a fluid lumen and inflation lumen therein. An exterior surface of the inner tubular member defines a fluid flow port in fluid communication with the fluid lumen and located along a region of the inner tubular member. Catheter further includes an outer member having a distal section movable relative to the inner tubular member and having an interior surface. A piston balloon is coupled to the inner tubular member distal to the fluid flow port and is in fluid communication with the inflation lumen. A pressure chamber is in fluid communication with the fluid flow port. Fluid introduced through the inflation lumen inflates the piston balloon to seal against the interior surface and fluid introduced through the fluid flow port and into the pressure chamber applies a force to urge at least the distal section of the outer member in a proximal direction.

摘要： Described herein are flexible implantable devices or stents that can, for example, navigate the tortuous vessels of the neurovasculature. The devices can also conform to the shape of tortuous vessels of the vasculature. In some embodiments, the devices can direct blood flow within a vessel away from an aneurysm or limit blood flow to the aneurysm. Methods and structures are provided for adjusting, along a length of the device, the porosity of the device while maintaining a cross-sectional dimension. In some embodiments, small hooks releasably engage the stent at a proximal end and are able to resheath the stent by retracting a proximal retaining member where the hooks are coupled to. The hooks straighten, unfurl, or otherwise disengage the stent when either unrestrained by a catheter or when coming into contact with an external stimulus found in the patient's vasculature.
