A system for performing minimally invasive procedures in a body lumen of a patient including a flexible catheter having a first lumen and a second lumen, the first and second lumens terminating in a distal opening at a distalmost end of the catheter. First and second flexible guides are separate components from the catheter and removably insertable into the flexible catheter and movable axially through the lumen of the flexible catheter. The guides have a channel extending therethrough configured and dimensioned to receive an endoscopic tool for axial movement therein. The flexible guides havea longitudinal axis and a tube distal portion movable to a pre-shaped curved position with respect to the longitudinal axis when exposed from the flexible catheter. 本发明涉及一种用于执行在患者体腔中的微创手术的系统，该系统包括具有第一管腔和第二管腔的柔性导管，第一和第二管腔终止于在导管最远端的远端开口。第一和第二柔性导向装置是与导管分开的独立部件并且可移除地插入柔性导管中且可经过柔性导管的管腔轴向地移动。这些导向装置具有延伸经过其中的通道，该通道构造成且尺寸被设计成接纳内窥镜工具以便在其中的轴向移动。柔性导向装置具有纵向轴线、和当从柔性导管暴露时可相对于纵向轴线移动到预成形弯曲位置的管远端部。
