Abstract: A securement structure is positioned inside a channel of a first medical device to facilitate securement of the first medical device to a second medical device. The first medical device may be a ligation banding cap, and the second medical device may be an endoscope. The securement structure is adapted to be compressed between the second medical device and the first medical device to secure them together. This allows parts of different sizes to fit together.

Abstract: An actuation line is positioned external to the support structure lumen of a medical device. The medical device, which may be a ligation banding cap assembly, may comprise a support structure having a support structure lumen therethrough, an external channel on the outer surface of the support structure, and an actuation line positioned at least in part in the external channel. The external channel may be defined by raised ridges on either side of the external channel. The external channel may be recessed in the outer surface of the support structure. When the medical device is attached to a second elongated medical device, the actuation line is external to the support structure lumen of the medical device and the second elongated medical device.

Abstract: A comb structure has a primary, longitudinally extending tube, and a plurality of transversely extending tubes. The primary tube has a fitting secured at one end and is closed at the other, while the secondary tubes have ports at their free ends. The fitting is manually securable to a top of a squeeze bottle that contains a hair treatment chemical. The comb structure is of unitary construction and is manually secured to the bottle with sufficient mechanical strength that the comb structure and the bottle form a single device that can be used under single-handed operation.
