摘要：
A medical device for performing an endoscopic procedure through an endoscope is provided. The device includes an elongated catheter having a first lumen and a second lumen； a needle system for injecting a target tissue within a body； and a base disposed at a proximal end of the catheter. The actuator tube is inserted through the base and the first lumen. A needle housing member is positioned between the needle and the first lumen when the needle is in a stored position. The needle housing member has a predetermined length so that the needle is disposed within the needle housing member when the needle is at the stored position. The needle housing member has a continuous inner surface and prevents the needle from penetrating the first lumen. The needle includes a tip, deflected towards a center axis of the needle. The first and second lumens have different deflected forces.
