Description
本特許出願は開示内容の全体が本明細書に参考文献として含まれる2001年6月29日に出願されている米国仮特許出願第60/302,070号に関連していてその恩典を主張している。
本発明は、一般に、超音波外科器具に関連しており、特に、体内音波力学的療法用の一定の超音波外科器具に関連している。
中空コア型および中実コア型の両方の種々の器具を含む超音波器具が多くの医療的状況の安全で効果的な治療のために用いられている。超音波器具、特に中実コア型の超音波器具は種々の超音波周波数において一定の外科エンド−エフェクタに伝達される機械的振動の形態のエネルギーを用いて生体組織を切断および/または凝固するために使用できるという理由により有利である。超音波振動は、適当なエネルギー量において一定の適当なエンド−エフェクタにより生体組織に伝達される場合に、組織を切断、切除、または焼灼するために使用できる。中実コア技法を利用している超音波器具はその超音波トランスデユーサから導波管を介して外科エンド−エフェクタに伝達可能な超音波エネルギーの量により特に有利である。さらに、これらの器具は内視鏡または腹腔鏡による処置等のような最少侵襲性の処置に特に適しており、この場合に、そのエンド−エフェクタは一定のトロカールを通過して外科部位に到達する。
本発明は一般に超音波外科器具に関連しており、特に、体内音波力学的療法のための超音波外科器具に関連している。特に、本発明は種々の薬剤の配給および活性化を増進/調整して組織融除を達成できる一定の体内外科器具に関連している。代表的な薬剤は、とりわけ、種々の鎮痛薬、抗炎症薬、抗癌剤、静菌薬、神経活性剤、抗凝固薬、例えば、遺伝子配給のための高分子量タンパク質等を含む。上記器具はkHzおよび/またはMHzの周波数範囲において動作するように設計されている。
本発明による組織を治療するための一定の方法は一定の外科器具を供給する工程を含み、当該器具は一定のハウジング、当該ハウジングに接続している一定のトランスデユーサ、当該トランスデユーサを囲っている一定の半透過性の膜、一定の薬剤、および一定の薬剤配給システムを備えており、さらに上記方法は、上記外科器具を一定の患者の体内腔の中に挿入する工程、当該患者に一定の薬物を配給する工程、および上記外科器具によりその薬物を局所的に活性化する工程を含む。本明細書における目的において、局所的にとは、上記器具におけるエンド−エフェクタから約0.5mm乃至50mmの一定範囲内として定められている。さらに、本発明による別の工程は止血を達成する工程、組織を切除する工程、組織を凝固する工程、および組織を切断する工程を含む。
