본 개시 내용은 내시경 검사의 분야에 관한 것이다. 구체적으로, 본 개시 내용은, 채색된 마커 및 하나 이상의 이차 마커를 이용하여 카테터의 원위 부분이 신체 내에서 가시화될 수 있게 하는 시스템 및 방법에 관한 것이다. 특히, 본 개시 내용은, 의료 장치가 신체 내강 내의 전개를 위해서 적절히 배치되는 때를 표시하는 시스템 및 방법에 관한 것이다. A system, comprising an outer catheter, the outer catheter including a proximal end, a distal end; and a lumen extending therebetween; a first marker and a second marker; an inner catheter slidably disposed within the lumen of the outer catheter; and a stent disposed over the inner catheter, the stent being configured to transition from a first configuration to a second configuration when not disposed within the lumen of the outer catheter, the stent comprising a proximal retention member when in the second configuration; wherein the outer catheter is proximally retractable together with the inner catheter and the stent with respect to a reference position within a body lumen; wherein the first marker is positioned with respect to the outer catheter, inner catheter, or both, and with respect to the stent, such that confirmation within the body lumen of the first marker proximal to the reference position denotes that the entire proximal retention member is deployable proximally relative to the reference position.
