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: 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filament may, in conjunction with the aperture and sidewall, releasably retain the coil until the first filament is withdrawn.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: Doxorubicin is extracted from blood using anionic material, such as a resin comprising sulfonated polystyrene divinylbenzene beads, and polyethersulfone membrane, or both. After exposing the resin and/or membrane to blood in order to remove doxorubicin therefrom, the doxorubicin maybe extracted from the resin and/or membrane by exposing the material to an extraction solution, sonicating the extraction solution to enhance release of the doxorubicin, and repeating the exposure and sonication in order to remove substantially all of doxorubicin from the resin.

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filament may, in conjunction with the aperture and sidewall, releasably retain the coil until the first filament is withdrawn.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