A cylindrical carrier projects distally away from the sleeve and can carry one or more resilient tissue compression rings in a stretched configuration. A push ring is slidably disposed on the carrier, and an actuator is connected to the push ring. The actuator extends through the carrier, around a distal end of the carrier, and to the push ring to connect thereto such that when the actuator is pulled proximally, the push ring is urged distally on the carrier to push at least one compression ring off the carrier, at which point the compression ring is relaxed to assume a small configuration and clamp target tissue. The actuator may include a distal segment made of a flat ribbon.
