Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
178 words
A fixation device formed in the shape of a screw, said fixation device being adapted to be grafted into a biologically active structure, said fixation device being interactive with said structure and forming a part of said structure, said fixation device being compatible with the functional characteristics of said structure, said fixation device comprising: a) a head portion functionally adapted to provide rotational movement to said fixation device, said head portion being larger in diameter than the longitudinal body portion, said head portion diameter ranging from about 1 to 12 mm, and said head portion being cylindrical with at least two flat sides; b) said head portion being fixedly attached to a longitudinal body portion; c) said longitudinal body portion including means being at least partially threaded, and said longitudinal body portion having a threaded diameter ranging from 1 to 8 mm; and d) said head portion has a slot, said slot being perpendicular to said longitudinal body portion and adapted to receive a rotational tool; e) wherein said fixation device being made of mineralized cortical bone tissue.
