Abstract
Description
図2Aの円板環20では、小径針24で箇所21を穿刺する。好適な針のサイズは20ゲージである。図2Bの小径(即ち、1mmから3mm)の高圧バルーンカテーテル26が、円板環20の穿刺部21を通して導入される。カテーテル26に取り付けられたバルーン28の髄核18内における位置はX線透視法を使って確認される。円板拡張と注入用の装置を挿入するのに必要な穿刺は、穿刺部を完全に閉じることができるぐらい、又は注入された生体適合性材料が捕捉された状態に留まるに十分な程度に閉じることができるぐらいに小さく、即ち3mm以下である。生態適合性材料を注入後に円板空間で硬化させる場合には、注入された生体適合性材料の捕捉が保証される。プラグ又はシーラント等の材料の様な環閉鎖装置を使用するのは随意である。
