A vascular graft deployment tool may include a grip, an elongated mandrel positioned distal of the grip, a vascular graft, at least part of which is disposed coaxially about the mandrel, a sheath assembly including a distal sheath portion and a proximal sheath potion, wherein the distal sheath portion and the proximal sheath portion are configured to constrain the vascular graft against the mandrel in an insertion diameter and a actuator that is moveable relative to the grip and engages the sheath assembly, wherein operation of the actuator causes at least one of the distal sheath portion and the proximal sheath portion to separate longitudinally to free at least a portion of the vascular graft. Further, a vascular graft is expandable from an insertion state to a deployed state and at least two suture cuffs are located between opposed ends of the vascular graft.

A vascular graft may be configured to transition from an insertion state to a deployed state. The graft comprising a proximal end having an expandable mesh, a distal end having an expandable mesh, and at least one suture cuff positioned between the proximal and distal ends, wherein each suture cuff comprises additional material relative to the proximal and distal ends that is configured to form when the vascular graft transitions from the insertion state to the deployed state.

A vascular graft deployment tool may include a grip, an elongated mandrel positioned distal of the grip, a vascular graft, at least part of which is disposed coaxially about the mandrel, a sheath configured to be withdrawn proximally that constrains the vascular graft against the mandrel in an insertion diameter and an actuator that is moveable relative to the grip and engages the sheath assembly. A first operation of the actuator causing withdrawal of the sheath to free at least a distal portion of the vascular graft and a repeated operation of the actuator causing further withdrawal of the sheath to free a proximal portion of the vascular graft.

Various devices are described to provide filtering of flow from the aorta to the left carotid artery and the right carotid artery. The filters can be brought into a desired position through one or more peripheral arteries. A single filter device can provide the desired filtering or a plurality of devices can be used. In particular a single filter device can span between the brachiocephalic artery and the left carotid artery. These filter devices can be used effectively to capture emboli generated during procedures on the heart so that emboli do not travel to the patient's brain where the emboli can cause a stroke or other adverse event. In particular, these filters can be used during percutaneous procedures on the heart, such as endovascular heart valve replacement.

A drug supply device includes: a tube body; a first expansion member configured to be expanded to a first outer diameter and a second expansion member configured to be expanded to a second outer diameter that is greater than the first outer diameter, the first expansion member and the second expansion member being positioned on a distal-end side of the tube body; and a masking member that extends between the expansion members and that is connected to outer surfaces of the expansion members at two ends thereof. The tube body includes an outlet that opens between the expansion members and a channel that is in communication with the outlet, the masking member is formed in an arc shape in a lateral cross-section that is orthogonal to the longitudinal axis, and the masking member stretches between the expansion members in a state in which the expansion members are expanded.

One disclosed embodiment comprises a method for treating lesions in the carotid artery of a mammalian body. The method comprises transcervical access and blocking of blood flow through the common carotid artery (with or without blocking of blood flow through the external carotid artery), shunting blood from the internal carotid artery and treating the lesion in the carotid artery.

A balloon catheter for treating aneurysms or other intraluminal target sites, having at least one bypass window through which blood flows temporarily and out at least one end hole, and a balloon mounted near the end hole, such that there is no need for repeated inflation/deflation cycles. The invention has an elongated tube, a balloon disposed between the most distal said window and said end hole, and at least two channels. A first channel passes from the proximal end of said tube to the bypass window to allow blood to flow into said window and out said end hole, and a second channel passing from the proximal end of said tube to said balloon to allow inflation material to enter said balloon. In optional embodiments, a micro-catheter may pass through to treat a target site; the inner tube and balloon may be branched to facilitate treatment at a vascular branch, such as for a wide-neck aneurysm by balloon tamponade, a micro-catheter extension or other device passing through a bifurcation hole at the branch point.

There is provided with a method. A cardia and a pylorus of a stomach of a patient is blocked. The stomach is inflated. The stomach is secured within an abdominal cavity of the patient.

In one aspect, an arteriovenous access valve system may generally include a first valve configured to be positioned at or adjacent to an end of an arteriovenous graft and a second valve configured to be positioned at or adjacent to an opposite end of the arteriovenous graft. In addition, the system may include an actuator assembly in fluid communication with the first and second valves. The actuator assembly may include a housing, a driver assembly positioned within the housing and a drive magnet positioned within the housing. The drive magnet may be rotatably coupled to the driver assembly such that, when the drive magnet is rotated, the driver assembly is configured to be rotatably driven so as to supply fluid to the first and second valves or to draw fluid out of the first and second valves depending on a rotational direction of the driver assembly.

Disclosed is a treatment device for occluding a body lumen, including: an elongated body which can be inserted into the body lumen; a flat portion forming section which is supported by the elongated body, is expandable widthwise on a more distal side than the elongated body, and deforms the body lumen into a form having a flat portion at a distal portion of the flat portion forming section upon the expansion of the flat portion forming section within the body lumen; and an administering section which administers, toward the flat portion formed by the flat portion forming section, a treatment which acts to occlude the flat portion.
