Abstract
【選択図】図1
Description
[0015]「固定された」−装置の作動環境内で分離不能である。
図12および図13によって示される実施形態は、以下のように機能する。バルーンカテーテルが治療部位まで送達される。治療部位において、オペレータは、膨張液を膨張可能なバルーン115内に注入し、膨張可能なバルーン115を拡張させる。拡張したバルーンは、1本または複数本のスコアリングワイヤ135を病変に押し付ける。その箇所において、オペレータは振動手段1315を起動し、振動手段1315は、ハブ1310、ハブ近位部分242または移動可能なSCW端部138を振動させ、これによりSCW135を振動させる。このため、振動手段1115から、病変に接触するスコアリングワイヤに振動が伝わる。振動するスコアリングワイヤは、石灰化を破砕し、病変に切り込む。
