molding resin for use with a mineral filler since the nylon like character of pea ensures good adhesion of the polymer to the filler if a silane coupling agent such as trimethoxyaminopropyl silane is used to pre treat the mineral filler the spinal fusion devices of the present invention produced as described above function in a manner similar to commercially available titanium fusion cages these cages are packed with autologous bone chips which eventually regenerate new bone that grows through the holes in the cylinder walls as well as through the open ends of the tube thereby bridging or u201c fusing u201d the adjacent vertebral bodies a superior long term result is anticipated with fully bioabsorbable devices of the present invention since the implant gradually transfers loads onto the new bone thereby stimulating it to remodel into denser more functional tissue ultimately the fully bioabsorbable device of the present invention will be completely replaced with new bone that can remodel into normal healthy tissue other thinner more flexible tubular devices such as stents can be produced from fibers of the present invention by placing woven nonwoven knitted or braided fabric or mesh around a mandrel and injection molding upon cooling and removing the mandrel a tubular stent with the desired degree of stiffness and porosity imparted by the surface topography of the mold cavity or mandrel core will be obtained such stents are useful in a variety of surgical applications such as.
