Description
本願は、2004年11月4日に出願された、米国仮出願番号60/625,005の利益を主張する。この米国仮出願の開示は、その全体が本明細書中に参考として援用される。
(発明の技術分野)
本開示は、一般に、医療カテーテル装置に関し、そしてより特定すると、カテーテル挿入装置に関する。
カテーテルは、流体を身体の空洞、管、および脈管内に投与するための、公知の医療デバイスである。種々の公知のカテーテルデバイスが、身体内の流体の同時の引き抜きおよび導入のために、使用されている。これらのデバイスは、複数の管腔を利用し得る。例えば、二方向の流体の流れを容易にする二重管腔カテーテルであり、これによって、一方の管腔は、血液の引き抜きを実施し、そして他方の管腔は、処理された血液を脈管に導入する。血液透析用途において、カテーテルは、血液を血管から引き抜き、そしてこの血液が人工腎臓デバイスによって処理された後に、処理後の血液を血管に戻すために使用される。
従って、脈管の外傷および患者の不快を減少させて、身体脈管内への配置を容易にし、先行技術の不利な点および欠点を克服する、カテーテル装置が提供される。最も望ましくは、このカテーテル装置は、容易にかつ効率的に製造され、そして組み立てられる。
開示されるカテーテルおよび使用方法の例示的な実施形態は、被験体の流体の投与のための医療カテーテルの観点で議論され、そしてより具体的には、身体脈管内への配置を容易にするカテーテルの観点で議論される。このカテーテルは、外傷を減少させ、そして患者の合併症を防止するように、有利に構成される。本開示は、様々なカテーテル(例えば、血液透析カテーテル、腹膜カテーテル、注入カテーテル、PICC、CVC、ポート、胆管カテーテル、尿道カテーテル)と共に、あらゆる急性および/または慢性のカテーテル用途において使用され得ることが予測される。
