Abstract: Various devices and methods having detachable handles at a proximal end thereof for use in the working channel of an endoscope. The detachable components at the proximal end allow the endoscope to be retracted and removed over the device, while leaving the device in place for purposes such as tissue manipulation.

Abstract: A closure device with a fixed upper jaw and a pivoting lower jaw, and a hook like tooth extending from the upper jaw such that the upper jaw may be used to engage distal mucosa tissue and pull the tissue over a mucosal defect while engaging proximal tissue with the lower jaw.

Abstract: The present invention relates to clips and, specifically, to endoscopic clips. Clips of the present invention comprise a rail, a proximal prong, and a distal prong. Clips of the present invention comprise multiple sequentially deployed folding prongs, which may deploy in a substantially perpendicular manner by rotating from a folded position flush with a rail to about a 90° angle relative to the rail. The proximal prong may be both rotatable and longitudinally slidable relative to the rail. The distal prong may be rotatable relative to the rail. Folded clips of the present invention may be delivered to a target site within a sheath. The sheath may be retracted from the folded clips to permit deployment and the sheath end may be subsequently used to push the longitudinally slidable proximal prong towards the distal prong for clamping. The clip is releasable, and may be released from a latch wire.

Abstract: The invention relates to a measuring device 5 of the type which detects the interruption of a beam of radiation (e.g. light 20) by an object (50 FIG. 1) in the beam. The device includes a light emitter 12 and a light detector 32 each enclosed in a housing 10 and 30. In order to accommodate different spacings between the housings different caps 14 having varying size apertures 11 are fittable to the housings. This allows varying amounts of light to be issued and/or detected. Other ways of adjusting the amount of light passing through the cap are disclosed.
