  • Excavation support structure
    Patent number: 5934840
    Abstract: An excavation support structure has a vertical face and includes an array of two or more soil-cement columns positioned internal to the vertical face. The columns are positioned within the array so that each of the columns is not connected by soil-cement to any other column. Soil surrounds the soil-cement columns except where the soil-cement columns meet the vertical surface. The soil-cement columns are distributed within the support structure so as to form a composite structure with the soil.

  • Guidewire straightener
    Patent number: 5125905
    Abstract: A guidewire straightener that is adapted to fit on the end of a protective tube containing a guidewire used for introducing a catheter into a patient's bloodvessel. The guidewire straightener has a flexible end that flexes inwardly to grasp the guidewire when the guidewire is inserted into the end of the protective tube. The guidewire is thus prevented from migrating with respect to the protective tube during packaging, shipping and handling.
