  • Patent number: 5707383
    Abstract: A surgical abrading instrument for removing soft bodily tissue includes a stiffening support member and an abrasive member formed of a rubbery polymeric material. The abrasive member is mounted on the stiffening support member and includes an integral abrasive surface having a roughness to remove soft bodily tissue when the abrasive member is driven against the tissue via movement of the stiffening support member. The abrasive member can be of integral one-piece construction, in which case the abrasive member can also be formed simultaneously with attachment to the stiffening support member. In one embodiment, the stiffening support member includes a cylindrical shaft with proximal and distal ends, and the abrasive member is formed at the distal end of the shaft for rotation about a longitudinal axis thereof.

  • Patent number: 4141088
    Abstract: A prosthetic hip joint for use in the replacement of at least a portion of defective hip joint. The hip joint includes a femoral component and an acetabular component. The femoral component includes a stem that has an uninterrupted outer surface and is continuously tapered from the proximal end of the stem to the distal end. The stem is oval shaped in cross-section with the longer axis of the oval being in the lateral-medial plane and the shorter axis being in the anterior-posterior plane. The neck portion of the device in cross-section is narrower in its anterior-posterior dimension than its lateral-medial dimension. The femoral component is available with different length neck portions to allow the tightness of the hip joint to be varied. However, even when the length of the neck portion is varied, the distance between the center of the head and the longitudinal axis of the stem and the curvature of the stem are not varied.
