Abstract: A laparoscopic nephrectomy device is disclosed. The device has an upper jaw and a lower jaw designed to clamp a portion of an organ, such as a kidney, so as to cut off blood flow locally to a portion of that organ. The upper jaw includes a mid-jaw piece and a top jaw piece, with each piece separately articulated. The mid-jaw piece is pivotably connected to the lower jaw. A top jaw piece is pivotably connected to the mid-jaw piece. The mid-jaw and top jaw pieces include a mechanism to fix the angular orientation of the mid-jaw and top jaw pieces with respect to one another, including a retractable slide piece that is carried by the mid-jaw piece and received in a slot in the top jaw piece. The jaws have insulated troughs that carry electrode structure for applying coagulative therapies.

Abstract: A chest protector to reduce risk of commotio cordis. The chest protector includes an inner protector member and an outer shell. The inner protector member includes a protector plate and one or more supporting members. The protector plate has a first surface facing the user's chest and a second surface facing away from the user's chest, and the first surface has a central portion and side portions. The one or more supporting members are attached to the side portions of the first surface of the protector plate but not to the central portion of the first surface such that an air space is defined by the central portion of the first surface and the one or more supporting members. The protector plate and the one or more supporting members are configured such that the central portion of the first surface of the protector plate is spaced apart from the chest.
