Abstract
Description
本願は、米国仮特許出願第61/084,202号(2008年月7日28出願)の米国特許法第119条第(e)項の優先権の利益を主張し、この出願の開示は、その全体が本明細書に参考として援用される。
椎間板の損傷は、一般的に、相当な治療期間の床上安静、理学療法、活動の変更、および鎮痛剤によって治療する。損傷した椎間板を修復し、損傷した椎間板の外科的除去を回避しようとする多くの治療が存在する。例えば、椎間板除圧術は、髄核を摘出するかまたは収縮させることにより、線維輪および神経への圧力を減圧するおよび減少させるために使用される手技である。より侵襲性の低い顕微鏡下腰椎椎間板摘出術および自動経皮的腰椎椎間板摘出術は、線維輪内に横方向に挿入した針を通して吸引することにより椎間板の髄核を摘出する。別の手技は、椎間板の変性を治療するか、遅延させるか、または予防するために、椎間板増強デバイスを移植することを伴う。増強とは、(1)椎間板ヘルニアの修復、損傷した線維輪の支持、および線維輪断裂の閉鎖を含む線維輪の増強と、(2)髄核への物質の追加を含む髄核の増強の両方を意味する。観血的アプローチを含む従来の治療デバイスおよび技術の多くは、蛍光透視による誘導下で椎間板の一部を穿刺するために筋肉の切開または経皮的手技を伴うが、直接的な可視化は用いない。いくつかの治療もまた、推測される損傷領域に薬物を注射することによって、または癒着を溶解させることによって、椎間板起因の疼痛を減少させようとする。しかしながら、これらのデバイスもまた、外科医にとっての触覚、または、外科医が周囲の組織を傷付けることなく操作できるという点においては、提供するところは少ない。一般に、これらの従来システムは、椎間板に到達するために外部からの可視化に依存するため、任意の種類のリアルタイムの搭載型可視化能力を持たない。
