Abstract
Description
Sandoe、E.およびSigurd,B.、Arrhythmia,Diagnosis and Management,A Clinical Electrocardiographic Guide、Fachmed AG、1984年。 JL Cox、TE Canavan、RB Schuessler、ME Cain、BD Lindsay、C Stone、PK Smith、PB Corr、およびJP Boineau、The Surgical treatment of atrial fibrillation.II、intraoperative electrophysiologic mapping and description of the electrophysiologic basis of atrial flutter and atrial fibrillation、J Thorac Cardiovasc Surg、1991年、101巻:406−426頁。
したがって、国際公開第03/003948号による装置は、それが、作用の部位の近傍にある組織を害さないか、または他の点で負の作用を与えることを確保するために、作用の部位から除去されるべきである。さらに、機能的機構に影響を及ぼすために、先行技術による装置は、他の有効な物質を供給されなければならず、その有効な物質は、好ましい治療部位で放出されうる。したがって、別の供給段階が、このような装置を製造する上で統合されなければならない。
形状記憶材料の例は、ニッケル(54−60%)およびチタンより構成される合金であるニチノールである。微量のクロム、コバルト、マグネシウムおよび鉄も存在しうる。この合金は、恒久的形状を回復するためにマルテンサイト相転移を使用する。形状記憶材料は、形状記憶効果がガラス転移または融点に基づいている形状記憶重合体からも形成されうる。このような形状記憶重合体は、材料の重合体または適切な特性を有する材料の組合せを形成することによって生成されうる。例えば、形状記憶重合体は、n−ブチルアクリレートと組み合わせたオリゴ(e−カプロラクトン)ジメタクリレートから作製されうる。さらに、生物分解性または生物吸収性材料を、これらの形状記憶重合体を形成するために使用しうる。このような生物分解性または生物再吸収性材料は、例えば、重合体、セラミック、または金属性材料でありうる。
切断装置26の加熱を提供するであろう電流に付着させることである。それにより、組織を、この加熱によっても死滅させ、切断装置26の効果を増強させうる。さらに、形状の変化を起こさせる力も増大させ、そして切断装置の形状変化を加速させる。
心臓拍動調節系における障害の治療法であって、
一過性送出形状にある組織切断装置を、血管系を通して、心臓に隣接する体内管に、および/または心臓に挿入すること、
前記一過性送出形状から、拡張した送出形状を介して、さらなる拡張形状に組織切断装置の形状を変化させ、そして前記組織の少なくとも外側表面を越えて伸張すること、それにより
上記心臓組織および/または上記体内管を切断するために構成された切断作用を作り出すこと、それにより
それゆえに構成された組織切断装置を介して、その異所を分離することによって、前記組織を切断することにより心臓組織での所望でない信号伝達を減少させること、そして
前記の拡張した送出形状から前記のさらなる拡張形状まで前記組織切断装置の形状を変化させる間またはその後に、組織切断装置を生物分解することを包含する。
