Abstract: The invention relates to a device for providing controlled restriction of a hollow conduit in a body. The device may include a band element having a tunnel section with a proximal opening and a distal opening. The device may further include a length of the band extending from the proximal opening. The device may further include a controller, removably connected to the distal opening, comprising an adjusting mechanism for changing a diameter of the band. The end of the band may be insertable through the proximal opening to form a loop around a hollow conduit, and the end of the band length may be advanced into the controller to permanently engage with the adjusting mechanism. After adjusting the diameter of the band, the band may be secured and the controller disconnected, leaving the band and securing means around the hollow conduit.

Abstract: The present invention is a mouthguard to be used in sports to protect the mouth and teeth from blows to the face and head. The mouthguard has a three layer laminate construction and is fabricated from thermoplastic material that may be softened in hot water to enable a user to form it to the contours of his or her mouth. The mouthguard is formed from an upper portion shaped into a channel with holes distributed on the channel floor and a lower platform with posts aligned to fit into the holes. A part of the posts extend from the upper portion to the platform to form gaps between the upper portion and the platform with the gaps acting as air cushions. In one embodiment, a strap is attached to the assembled mouthguard.
