Abstract: A capsule configured for collecting samples in the intestine, comprising a body delimiting at least one compartment for receiving samples and comprising at least one opening for samples intake, and a mobile mechanism for opening and/or closing the opening controlled by the dissolution of a material which is dissolvable in the intestine.

Abstract: A method for measuring the displacements of a vertebral column, a vertebra of the column including a location marker attached thereto and providing a location system with an orientation of the location marker, the method including: a detection of an initial orientation of the location marker associated with a vertebra, a determination of an initial orientation of a vertebral plane parallel to at least one end plate of the vertebra, and a calculation of a geometric transformation associated with the vertebra correlating the initial orientation of the vertebral plane with the initial orientation of the location marker, a detection of the current orientation of the location marker, and a calculation of the current orientation of the vertebral plane of the vertebra from the current orientation of the location marker and the geometrical transformation associated with the vertebra.

Abstract: A system for measuring the displacements of a vertebral column having a segment comprising at least one vertebra having a body delimited by an upper vertebral end plate and a lower vertebral end plate, and each vertebra in the segment having a location marker associated, attached thereto and providing a location system with an orientation of the location marker, the system including a localizer configured to detect the initial orientations of the location markers, and a microprocessor configured to determine, for each vertebra, an initial orientation of a vertebral plane parallel to at least one end plate of the vertebra, and to determine the current orientation of the vertebral plane of the vertebra from the current orientation of the location marker associated and the geometrical transformation associated with the vertebra.

Abstract: A method for measuring the displacements of a vertebral column includes: an initial step, for each vertebra in a segment, including: detection of an initial orientation of the location marker associated with the vertebra, determination of an initial orientation of a vertebral plane parallel to at least one end plate of the vertebra, and a calculation of a geometric transformation associated with the vertebra correlating the initial orientation of the vertebral plane of the vertebrae with the initial orientation of the location marker associated, and; a step measuring displacement of at least one vertebra, including: detection of the current orientation of the location marker associated with the at least one vertebra, and a calculation of the current orientation of the vertebral plane of the at least one vertebra from the current orientation of the location marker associated and the geometrical transformation associated with the at least one vertebra.

Abstract: A method for performing computer-assisted orthopaedic surgery includes the steps of: (1) producing and displaying three-dimensional geometrical models of first and second bones, the first and second bones forming a joint; (2) identifying a zone of impingement between the first bone and the second bone on at least one of the bones; and (3) generating and displaying a color map of at least one surface of at least one bone, the at least one surface being within the zone of impingement, the color map including different colors representing different depths of bone to be removed in order to achieve an increased range of motion between the first and second bones.
