    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： An aneurysm occlusion system includes devices positionable within a cerebral blood vessel covering a neck of an aneurysm in the blood vessel. A component device includes an expandable tubular body, an expandable anchor, and a link connecting the body to the anchor. One or more devices deployed using a method according to the invention includes a novel feature that guarantees that the distal high coverage segment aligns with the neck of the aneurysm. A single device or multiple devices, used in conjunction with an embolic material or coil, may be combined to form a system according to the invention. When positioned and deployed strategically either alone or with a second device utilizing a method according to the invention, the system has a high coverage region covering a neck of an aneurysm, and a gap between the system and healthy vessel. The system and method prevent blood flow into an aneurysm while permitting blood flow through healthy vessel.

    摘要： A thromboembolic removal system for treating ischemic stroke includes an aspiration catheter and an elongate member having a separator on a distal portion of the elongate member. During use of the thromboembolic removal system, the aspiration catheter and elongate member are positioned in a blood vessel, with the elongate member extending through the lumen of the aspiration catheter. Vacuum is applied through the aspiration catheter and the separator is deployed distal to the aspiration catheter into contact with thromboembolic material within a blood vessel. Manipulation of the separator during aspiration can facilitate aspiration by loosening, separating, or softening pieces of thromboembolic material, by removing any clogs or flow restrictions within the lumen of the aspiration catheter, and/or by pushing or plunging loosened material towards and/or into the distal end of the aspiration catheter for subsequent aspiration out of the body.
