PROBLEM TO BE SOLVED: To provide a rapid, simple therapeutic device delivery apparatus which is elegant in design, relatively simple to manufacture, flexible and easy to guide through the vasculature of the body and is provided with excellent control over the device.SOLUTION: Therapeutic devices, especially vaso-occlusive devices or embolic coils, are delivered by an apparatus which includes a pullwire having tines which have an offset orientation that engages a therapeutic device. The pullwire passes through an opening of a headpiece. When the pullwire moves in a relative proximal direction, the tine moves toward a straight-line orientation, and the therapeutic device is liberated from the tine and from the pullwire. At this state, the therapeutic device is ready for deployment at a desired intraluminal location.COPYRIGHT: (C)2007,JPO&INPIT【課題】洗練されたデザイン、比較的簡単な製造、患者の脈管構造を通じた柔軟かつ容易な案内、および機器の優れた制御を備えた、迅速で簡単な治療器具の送達装置が必要である。【解決手段】治療器具、特に血管閉塞器具もしくは塞栓コイルは、治療器具と噛み合う、分かれた方向性を有する歯部を備えたプルワイヤーを含む装置によって送達される。プルワイヤーはヘッドピースの開口部を貫通する。プルワイヤーが相対的に近位方向に動く場合、歯部は直線方向に動き、治療器具が歯部およびプルワイヤーから解放される。この状態で、治療器具は所望の管腔内位置に配備する準備が整う。【選択図】図1
