- ハンドルと、
前記ハンドルにしっかりと固定された針であって、患者の血管の側壁を通して挿入されるように構成された遠位先端部を備える、針と、
前記針が通って延在する管腔を画定するカテーテルであって、遠位端に係合表面を備える、カテーテルと、
前記針の外部において前記カテーテルの前記管腔内に位置付けられた補強材であって、前記補強材が前記針上を遠位に前進するとき、前記カテーテルの係合表面上で遠位に押圧して、前記カテーテルを前記針上で遠位に、かつ前記血管の管腔を通して前進させるように構成された前記係合表面を備える、補強材と、
前記補強材に取り付けられた補強材ハブであって、前記補強材ハブが、前記ハンドルに対して並進するように前記ハンドルと移動可能に連結され、前記補強材ハブが、格納位置から展開位置に前記ハンドルに対して遠位に移動して、前記補強材及び前記カテーテルを前記針上で、かつ前記血管の前記管腔内の目標の深さまで前進させるように構成されている、補強材ハブと、を備え、
前記ハンドルが前記カテーテルに対して近位に移動すると、前記ハンドルは前記針と前記補強材の両方を前記カテーテルから近位に後退させるように構成される、システム。 - 前記ハンドルに解放可能に連結されたカテーテル接続ハブを更に備える、請求項1に記載のシステム。
- 前記カテーテル接続ハブが、前記格納位置から前記展開位置への前記補強材ハブの移動全体を通して、前記カテーテルに直接取り付けられる、請求項2に記載のシステム。
- 前記カテーテルに取り付けられたカテーテルハブコアを更に備え、前記補強材ハブが前記格納位置にあるとき、前記カテーテルが、前記カテーテルハブコアから遠位に延在し、前記カテーテル接続ハブを通過する、請求項2に記載のシステム。
- 前記補強材ハブが前記展開位置に前進したとき、前記カテーテルハブコアが、前記カテーテル接続ハブに取り付けられるように構成されている、請求項4に記載のシステム。
- 前記カテーテルハブコアが前記カテーテル接続ハブに取り付けられたとき、前記カテーテルハブコアと前記カテーテル接続ハブとの間に流体密シールを形成するように構成されたシール部材を更に備える、請求項5に記載のシステム。
- 前記ハンドルに連結され、後方位置から前方位置に移動するように構成されたアクチュエータを更に備え、前記アクチュエータが前記前方位置に前進したとき、前記アクチュエータが、前記補強材に係合し、前記補強材ハブを前記格納位置と前記展開位置との間の中間位置へと遠位に移動させるように構成されている、請求項1に記載のシステム。
- 前記補強材ハブが、前記アクチュエータが前記前方位置に留まるとき、前記アクチュエータから係合解除され、前記中間位置から前記展開位置へと遠位に移動するように構成されている、請求項7に記載のシステム。
- 前記補強材ハブが、前記アクチュエータに係合することなく、前記格納位置から前記展開位置へと遠位に移動するように構成されている、請求項7に記載のシステム。
- 前記補強材ハブに連結された追加のアクチュエータを更に備え、前記追加のアクチュエータが、前記中間位置から前記展開位置に前記補強材ハブを前進させるように構成されている、請求項7に記載のシステム。
- 前記アクチュエータが、前記ハンドルの対向する側面にある、請求項10に記載のシステム。
- 前記ハンドルが、前記補強材ハブに係合して、前記補強材ハブが前記展開位置から前記格納位置に戻るのを防止するように構成されており、前記補強材ハブが前記ハンドルによって係合されると、前記補強材の遠位部分が、前記針の前記遠位先端部を越えて遠位に延在して、前記針の前記遠位先端部との不注意な接触を防止する、請求項1に記載のシステム。
- 前記ハンドルが、前記補強材ハブに係合するキャッチを備える、請求項12に記載のシステム。
- 前記ハンドルが、前記補強材ハブから選択的に係合解除して、前記補強材ハブが前記格納位置に戻ることを可能にし、前記システムを非展開状態にリセットするように構成されている、請求項12に記載のシステム。
- 前記目標の深さが、前記カテーテルが前記血管に挿入される最終的な深さである、請求項1に記載のシステム。
