Abstract
Description
本願は、2012年11月19日に出願された米国仮特許出願第61/727,997号、2012年11月19日に出願された米国仮特許出願第61/728,006号、及び2013年2月4日に出願された代理人整理番号LLI-036の”Multimodal Imaging Systems, Probes, and Methods”という標題の米国特許出願について優先権の利益を主張するものであり、これら各文献の全体の開示は、参照することにより本明細書に組み込まれる。
1つ又は複数の回転ジョイントを使用して、プローブ内の2つの回転信号伝送路(光ファイバ及びワイヤ等の複数のコイル導体)をPIU内の固定信号伝送路に結合する。一実施形態では、各回転ジョイントは、その回転ジョイントがエアギャップを飛び越える光信号又はエアギャップを飛び越える電気信号を結合するように構成されているので、非接触式ジョイントである。光ファイバ光学式回転ジョイントは、一実施形態では、このジョイントの光ファイバ部分が、回転軸線と同軸となるように構成される。これは、次に、光ファイバの通過を可能にするようなキャビティ、チャネル又は開口部を規定する中央コアを有する又は他の方法で光路を規定する、電気式回転ジョイントを必要とする。さらに、両方の回転ジョイントは、回転部分及び固定部分を有するので、中央コアは、様々な構造構成要が回転要素及び非回転要素にリンクするのを可能にするようにサイズ決めされるように構成される。
図7には、カテーテル又はデータ収集プローブ本体の斜視図が示されている。カテーテル本体の回転可能なイメージングコアは、電線232を螺旋状に巻き付けられ且つトルクケーブル233によって包み込まれた中央光ファイバ230を含む。図7では、トルクワイヤは、切断形態で示されており、典型的には、露出された状態で示されている光ファイバセクションに沿って延びている。この構成によって、回転対称性が維持され、例えば本明細書で説明され且つ図示される回転複合ジョイントに光ファイバ230が整列されて、及びカテーテルの曲げ可撓性を維持しつつ、十分なトルク伝達が可能になる。
組織の組合せイメージング中に、PIUは、イメージングコアを引き戻すために、固定カテーテルシース234とスピンするイメージングコアとの間の相対的な直線運動を提供する。図8Aには、この直線運動を提供することが可能なPIUの実施形態が示されている。直線運動は、キャリッジ306に結合された回転複合ジョイント301をリニアレールシステム302上に取り付けることによって得られる。カテーテルシース及び外側ハウジング(図示せず)は、PIUの固定点303に堅く取り付けられる。イメージングコア・コネクタ304は、回転ジョイントのスピンするコネクタ端部305に取り付けられる。回転ジョイントを含むキャリッジ306が引き戻される際に、イメージングコアは、カテーテルシースに対して摺動される(矢印X)。
カテーテルは、ヒトの血液との接触を有しており、典型的には、単回使用の滅菌機器である。これとは対照的に、PIUは、血液との接触を殆ど有しておらず、カテーテルよりもはるかに高価である。その結果、PIUは、一般的に再利用され、使用中に減菌されない状態になる。これらの2つの部品を結合するように使い捨てコネクタが使用される。このコネクタは、高い信頼性を有する必要があり、且つ係合中のカテーテルの無菌性を維持する。使い捨てコネクタによって接続される4つのサブシステム又はコンポーネントが存在している。
