A system for placement in at least one blood vessel includes a main graft body, one or more inflatable channels, and a filling structure. The one or more inflatable channels are attached to the main graft body. The filling structure is inflatable around at least a portion of the main graft body and at least a portion of at least one of the one or more inflatable channels. Various systems further include a graft extension that is insertable into a lumen formed by the main graft body, where the filling structure is inflatable around at least a portion of the graft extension. A method includes inserting a main graft body into a blood vessel, filling an inflatable channel attached to the main graft body, and filling a filling structure to inflate around at least a portion of the main graft body and at least a portion of the inflatable channel.

Systems and methods with graft body, inflatable fill channel, and filling structure

Devices and methods divert blood flow from a first vessel to a second vessel and maintain blood flow in the first vessel. The device includes a first segment and a second segment. The first segment is configured to anchor in the first vessel. The first segment includes a window to allow blood to flow into the first segment, through the window, and distal in the first vessel. The second segment is configured to anchor in the second vessel. The second segment is configured to allow blood to flow into the first segment, through the second segment, and into the second vessel.

Devices and methods for increasing blood perfusion to a distal extremity

A catheter system can include a tubular body, and at least one of a targeting system coupled to the tubular body, an expandable member, or a fluid injection port. A method of identifying a bifurcation can include inserting a catheter system into a first vessel, positioning the catheter system at a first location, expanding an expandable member to occlude the first vessel, delivering contrast material so the contrast material pooling proximate to the expandable member, and reviewing a shape of the contrast material in the first vessel under fluoroscopy.

Methods for routing a guidewire from a first vessel and through a second vessel in lower extremity vasculature

A launching catheter for targeting a second vessel from a first vessel includes a catheter including a proximal portion and a distal portion including a needle aperture and a flat rectangular radiopaque marker. The flat rectangular radiopaque marker disappears under fluoroscopy upon rotation to provide information about rotational alignment of the launching catheter. The launching catheter includes a needle configured to extend through the needle aperture. A method of aligning the catheter includes rotating the catheter in a first blood vessel until the marker has a thickness (e.g., minimal thickness) under fluoroscopy. The thickness indicates rotational alignment of the catheter.

Method for accessing pedal veins for deep vein arterialization

Methods for accessing pedal veins

A system includes an inner filling structure around a stent-structure and an outer filling structure around the inner filling structure. The inner filling structure can be configured to produce a proximal seal with a first portion of an artery at a proximal end and a distal seal with a second portion of an artery at a distal end when the inner filling structure is in an inflacted state. The outer filling structure can have an inner surface surrounding at least a portion of the inner filling structure. The outer filling structure can be configured to be inflatable to occupy a space within an aneurysm at a lower pressure than a pressure in the inner filling structure.

Dual inflatable arterial prosthesis

A two-layered fenestrated vascular graft is provided for repair of diseased, damaged or aneurismal blood vessels. The fenestrated vascular graft is configured to be delivered transluminally and implanted within the lumen of a native blood vessel using catheter-based minimally-invasive surgical techniques. The vascular graft is fenestrated or perforated to facilitate making a fluid connection or anastomosis with one or more of the sidebranches of the vessel into which it is implanted. The vascular graft is adapted for implantation into blood vessels, such as the aorta, having tributary vessels or sidebranches along the section of the blood vessel to be repaired without occluding or obscuring the sidebranches. Methods are described for implanting the vascular graft into a patient's aorta for repairing thoracic or abdominal aortic aneurysms and for making a fluid connection or anastomosis with the tributary vessels or sidebranches of the aorta, such as the renal, hepatic and mesenteric arteries.

Fenestrated endovascular graft

Improved apparatus and methods are described for performing endarterectomy remotely via intraluminal techniques. A flexible blade dissector has a curved, diamond-shaped flexible dissecting blade mounted on a catheter shaft. The distal edge of the flexible dissecting blade is configured to form a dissecting edge for separating an atheromatous plaque from the medial layer of an artery wall. The flexible blade dissector may incorporate a steering mechanism to direct the flexible dissecting blade along a preferred path within the arterial wall. The endarterectomy method is performed by making an incision into an artery wall and initiating a plane of separation between an atherosclerotic plaque and the medial layer of the artery wall, inserting the flexible blade dissector into the plane of separation and advancing the flexible dissecting blade to longitudinally extend the plane of separation. Optionally, a second flexible blade dissector with a wider dissecting blade may be inserted coaxially over the catheter shaft of the first flexible blade dissector and advanced to laterally expand the plane of separation. Once the plaque has been freed from the entire inner circumference of the arterial lumen, the plane of separation is terminated on the distal and proximal ends, and the plaque is removed from the arterial lumen.
