A system for treating an aneurysm comprises an elongate flexible shaft and an expandable member. An expandable scaffold is disposed over the expandable member and may be expanded from a collapsed configuration to an expanded configuration. A double-walled filling structure is disposed over the scaffold and has an outer wall and an inner wall. The filling structure is adapted to be filled with a hardenable fluid filing medium so that the outer wall conforms to an inside surface of the aneurysm and the inner wall forms a substantially tubular lumen to provide a path for blood flow. In the expanded configuration the scaffold engages the inner wall of the filling structure. A tether is releasably coupled with the filling structure and the flexible shaft thereby constraining axial movement of the structures relative to each other.

Stent graft delivery system

A retrograde delivery catheter includes at its distal end an expandable member configured to at least partially occlude the coronary sinus of a patient's heart, and has a length and variable stiffness that allows the distal end to be selectively articulated so as to be positioned in the coronary sinus. The delivery catheter has a triple lumen construction with a primary lumen extending between the proximal and distal ends and configured to allow a cardioplegic fluid to be delivered to the coronary sinus. A second lumen provides for balloon inflation while a third lumen allows monitoring of a pressure within the coronary sinus. A torque may be applied and a reinforcement member within the delivery catheter provides improved torque transmission along the length of the catheter.

Retrograde cardioplegia delivery catheter and method for inducing cardioplegic arrest

Aneurysms are treated by filling a double-walled filling structure with a curable medium. The structures may be delivered over balloon deployment mechanisms in order to shape and open tubular lumens therethrough. The filling structures are preferably used in pairs for providing flow into the iliac arteries when treating abdominal aortic aneurysm.

Methods and systems for endovascular aneurysm treatment

A method and apparatus for working asphalt pavement, comprising one or both of a mechanical, hydraulic, electric, or pneumatic means for providing high-speed rotation; a rotary tool comprising a first end comprising a working surface and a second end adapted for connection to the means for providing high-speed rotation; and a screed, cooperatively arranged with the rotary tool, and comprising a working surface adjacent the working surface of the rotary tool, wherein the rotary tool is spun at high speed and applied to the asphalt pavement, frictionally heating the asphalt pavement to a temperature sufficient to work the pavement locally adjacent rotary tool and the screed. The screed and rotary tool comprising abrasion resistant materials selected from the group consisting of high-strength steel, hardened alloys, cemented metal carbide, polycrystalline diamond, and cubic boron nitride. The rotary tool and the screed apparatus may comprise a closed loop control system.
