Abstract: A tissue wall support incorporating magnetic elements with a mesh body, and a method of holding a tissue wall support to one side of the tissue wall using a magnet on the opposite side of the tissue wall. The support may be placed adjacent one side of the tissue wall and a magnet may be placed on an opposite side of the tissue wall to draw the support into contact with the tissue wall. Once the support is in contact with the tissue wall, the support can be fixed to that side of the tissue wall.

Abstract: A jaw protection device attached or attachable to a helmet to protect a jaw and especially a fractured jaw while it is healing to allow a professional hockey player or the like to continue playing. The device comprises a rigid plate which is rigidly attached to the helmet and which parallels the anatomical structure of the jaw, and the device is spaced from the facial structures so that objects such as hockey sticks and blades are prevented from entering to impact the jaw and so that impact forces are not transmitted from the device to the jaw.
