    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filament may, in conjunction with the aperture and sidewall, releasably retain the coil until the first filament is withdrawn.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.

    摘要： A device and method for permitting multi-modal treatment of vascular lesions are disclosed. The device includes an outer delivery catheter, an inner delivery catheter, and a guidewire. The catheter is designed to pass through the inner lumen of the outer delivery catheter, and the guidewire is designed to pass through the inner lumen of the inner delivery catheter. A stent may be loaded inside the outer delivery catheter, with the distal tip of the inner delivery catheter abutting against the proximal end of the self-expanding stent, for pushing the stent distally through the outer delivery catheter.

    摘要： A system for mechanically deploying intraluminal implants is disclosed. The system is used with an implant that is delivered and/or deployed via a pull wire and includes a handle having a funnel and receiving channel for receiving the pull wire, a slider having a thumb grip and a wedge, and a shuttle having a grabber for grasping the pull wire. The thumb grip is pulled proximally to retract the wedge to cause the grabber to grasp the wire and retract the shuttle but not the wire. An extension spring linked between the slider and the shuttle abruptly pulls the shuttle to retract the pull wire after the slider is fully retracted.

    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.
