  • Patent number: 6120510
    Abstract: The invention relates to a cutting guide instrument and method for enabling high-precision resection of the head (caput femoris) (8) of the neck (5) of a human femur (collum femoris) at a predetermined cutting angle (.alpha..sub.c) to the femoral shaft (9) and on a predetermined cutting level (L.sub.c) with respect to the proximal end of the caput (8). A support part (11) is fixed to the femur during the resection. A longitudinal guide carrier (12) is supported by the support part (11) and is aligned along the femoral collum (5) at said predetermined cutting angle (.alpha..sub.c) to the femoral shaft (9). A cutting guide (13) is supported by and movable along the axis (D--D) of the guide carrier (12) to a cutting position corresponding to the predetermined cutting level (L.sub.c). The invention also relates to the use of the instrument for performing such resection.

  • Patent number: 6102035
    Abstract: A single-use, disposable inhaler comprising: (1) a housing open at both ends, one end forming an air inlet and the other forming an air outlet, thereby defining an air flow path through the inhaler; and (2) an internal plate spaced above and below the housing, oriented parallel to the axis of the inhaler and parallel to the air flow path. The internal plate comprises a storage cavity formed therein, located near the air inlet, in which a single dose of a pharmaceutically active compound is placed. An individual using the inhaler inhales through the air inlet, creating an air stream which lifts the powder out of the storage cavity, into the air stream, and to the user.

  • Patent number: 6102179
    Abstract: A device for the transmission of one-way torque comprising an outer annular member having a plurality of radially inwardly projecting teeth each comprising a driving surface and a cam surface, and a shaft concentrically mounted with respect to the outer annular member and comprising a plurality of drive elements each having a driving surface and a cam surface. Rotation of the shaft or outer annular member in its driving direction causes engagement of a driving surface of at least one drive element with a driving surface of at least one tooth thereby resulting in joint rotation of the shaft and outer annular member. Rotation of the shaft or outer annular member in its non-driving direction causes engagement of the cam surface of at least one drive element with the cam surface of at least one tooth resulting in additional relative movement, substantially radially, between the drive element and tooth, thereby preventing rotational movement being transmitted between the shaft and the outer annular member.

  • Patent number: 6092660
    Abstract: A blister pack arrangement comprises at least one blister pack with individually openable blisters including a number of blisters containing placebo (placebo blisters), and a number of blisters containing an active pharmaceutical drug (drug blisters). Indicia means provides user information that indicates a predetermined sequence in which said blisters are to be opened during a trial period, said sequence being such that the placebo blisters are to be opened before the drug blisters. The blisters are not identifiable with each other either by sight or by said indicia means. An initially secret treatment code is to be broken after the trial period, revealing when in said sequence a switch is made from placebo to active drug.
