Abstract

본 발명은 외과 수술용 기구에 관한 것이다. 카테터는 환자 신체의 내강 계통 내부의 목표 부위에 도달하기 위하여 복합 가이드와이어(composite guidewire)를 사용한다. 복합 가이드와이어 조립체는 말초 또는 유연한 조직 목표부위에 도달하는데 특히 유용하다. 본 발명은 (적어도) 초탄성 말단부를 갖는 여러 부분으로 이루어진 가이드와이어 조립체를 포함한다. 본 발명에 따른 가이드와이어의 변형예로는, 와이어를 타이층(tie layer)으로 피복하고 나서, 카테터 내부에서 사용하기 위한 적합성뿐만 아니라 맥관 내강 내부와의 적합성을 향상시키기 위하여 하나 이상의 윤활 중합체로 피복된 코팅을 갖는다.
