  • Bioactive, bioabsorbable surgical composite material
    Patent number: 6406498
    Abstract: The Applicants' invention is a bioactive, biocompatible, bioabsorbable surgical composite that is fabricated bioabsorbable polymers, copolymers or polymer alloys that are self-reinforced and contain ceramic particles or reinforcement fibers, and also can be porous. The composite of the invention can be formed into devices like pins, screws, plates, tacks, bolts, intramedullary nails, suture anchors, staples, and many other devices, all of which are useful in bone-to-bone, soft tissue-to-bone or soft tissue-to-soft tissue fixation or in fixation of bioabsorbable and/or biostable implants in or on bone or soft tissue.

  • Biodegradable implant manufactured of polymer-based material and a method for manufacturing the same
    Patent number: 6228111
    Abstract: The invention relates to a biodegradable implant or the like manufactured of polymer-based material and intended to be installed in tissue conditions. In the macroscopic structure of the implant two or several zones are created in a manner that the biodegradable polymer-based material has in different zones a different detaching time from the macroscopic structure under tissue conditions.
