Abstract: A polyp trap has an upper housing with a domed, top view window for viewing tissue retained by a disk seated in a lower housing which is held in place by the upper housing, when the upper housing is coupled to the lower housing. In one example, the upper housing holds the disk in place by engaging a post, which doubles as a handle for removing tissue from the trap with the disk and transferring the tissue to a storage container or bag. Mating posts in the lower housing may engage guide holes in the disk to further secure the disk in the trap.

Abstract: A device for delivering an apparatus or object to a targeted location within a human subject is disclosed. The device includes a body, a handle mounted to and movable relative to the body, a tube, a cable, and retention unit. The tube has a first end fixed to the body and a second end fixed to the retention unit. The cable has a first end fixed to the handle and a second end remote from the body. The cable extends substantially through the tube. The retention unit applies a retention force sufficient to retain the capsule during endoscopic delivery to the targeted release location. Manipulation of the handle in a direction relative to the retention unit generates a force on the apparatus greater than the retention force. A method of use is also disclosed.

Abstract: A snare injection device for performing endoscopic transection procedures is disclosed. The device includes a snare system and a needle system, each containing actuator components separately routed in one of two channels of an elongated dual lumen. Deployment of the snare and needle are independently operated by two separate handle controls. The device includes needle travel stop and anti-puncture features for safety and ease of use.
