  • Publication number: 20110238147
    Abstract: 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.

  • Patent number: 7931659
    Abstract: 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.

  • Publication number: 20100174269
    Abstract: 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filament may, in conjunction with the aperture and sidewall, releasably retain the coil until the first filament is withdrawn.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.
