    • A delivery assembly includes a ring sleeve that fits snugly over a main endoscope on the distal end of the endoscope. An extension tube projects distally away from the ring sleeve and may be made integrally with the sleeve. The extension tube is off-axis from the ring sleeve and endoscope. A tube-like inner carrier is reciprocatingly disposed inside the extension tube. One or more resilient tissue compression rings are placed in a stretched configuration on the inner carrier. To push the rings off the carrier, the carrier is pulled proximally within the extension tube and the compression ring is thus pulled into contact with the distal end of the extension tube. Continued pulling of the carrier causes the compression ring to be pushed off the assembly onto target tissue, at which point the ring is relaxed to assume a small configuration and clamp the target tissue.
    • 输送组件包括紧密地配合在内窥镜的远端上的主内窥镜上的环套筒。 延伸管远离环套筒突出并且可以与套筒一体地制成。 延伸管与环套筒和内窥镜离轴。 管状内部载体往往布置在延伸管内。 一个或多个弹性组织压缩环被放置在内部载体上的拉伸构造中。 为了将环推离载体,载体在延伸管内被向近侧拉伸,并且压缩环因此被拉到与延伸管的远端接触。 载体的继续拉动使得压缩环从组件被推离到目标组织上,此时,环被松弛以呈现小的构型并夹紧目标组织。
