    摘要： A system for restoring blood flow through an occluded vessel in the cerebrovasculature is disclosed. The system includes a tubular element constructed of shape memory material eccentrically mounted on the distal end of an introducer. The walls of the tubular element are defined by standards and connectors, and the standards are oriented at an angle to the longitudinal axis of the tubular element. A method of manufacture of the system includes cutting a tube of shape memory material, conferring a twist on the cut tube, and heat setting the tube. The method further includes affixing the shape set tube to an introducer. A method of treatment using the system is also described.

    摘要： A thin film device, such as an intravascular stent, is disclosed. The device is formed of a seamless expanse of thin-film (i) formed of a sputtered nitinol shape memory alloy, defining, in an austenitic state, an open, interior volume, having a thickness between 0 5-50 microns, having an austenite finish temperature Af below 37° C.; and demonstrating a stress/strain recovery greater than 3% at 37° C. The expanse can be deformed into a substantially compacted configuration in a martensitic state, and assumes, in its austenitic state, a shape defining such open, interior volume. Also disclosed is a sputtering method for forming the device.

    摘要： A thromboembolic removal system for treating ischemic stroke includes an elongate member and a receiver on a distal portion of the elongate member. The receiver includes structural members arranged to form a sleeve having a central lumen. A plurality of the structural members form engaging elements having apex regions that extend into the central lumen. During use of the thromboembolic removal system, the receiver is advanced over a body of thromboembolic material within a blood vessel, causing the body to be received into the central lumen, and causing the engaging elements to engage the body within the lumen.

    摘要： Embolic coil implant systems and methods whereby coils are mechanically detachable are disclosed. The coils include a retention element that may be releasably retained within the distal end of an implant tool. The implant tool may include a fulcrum configured to engage a first filament and prevent the release of the coil when the first filament is engaged. Alternatively, an urging means and aperture may be disposed within the sidewall of the implant tool, and a first filament may, in conjunction with the aperture and sidewall, releasably retain the coil until the first filament is withdrawn. The implant tool may also include an alignment member for aligning the first filament.
