Absorbable fixation device with controlled stiffness for in-vivo treatment of the human body and insertion device

摘要

The resorbable fixation device is useful for treating torn bodily material in vivo. It has a tip (1), a head (2), and a cylindrically shaped shaft portion (3) lying between said tip (1) and said head (2). The shaft portion (3) has at least one retention element (4) protruding radially therefrom to facilitate insertion of said shaft portion (3) longitudinally into said bodily material in a forward axial direction extending from said tip (1) to said head (2) and to restrict movement of said shaft portion (3) through said bodily material in a backward axial direction opposite to said forward direction. The shaft portion (3) has further a hollow body (9) with at least one radial opening (5) extending transversely through the walls (6) surrounding said hollow body (9) and rendering said shaft (3) radially elastic. The walls (6) surrounding said hollow body (9) are provided with at least one stiffening element (7) providing a controlled stiffness to the fixation device. IMAGE
