Patent number: 5152993Abstract: A method of preparing an implant body in order to optimize the healing time of said implant, comprising bringing the implant body for a limited period of time into contact with a hydrogen peroxide solution at least on the surfaces intended to come into contact with surrounding tissue when implanted, the treated surfaces being cleaned by rinsing. The treatment of the implant surface with hydrogen peroxide can be supplemented with incorporation of biomolecules, such as peptides, proteins and steroids, and also other substances such as inorganic ions and crystals. The compounds to be coupled to the implant surface may promote the healing and/or binding of the surrounding tissue.Type: GrantFiled: July 18, 1990Date of Patent: October 6, 1992Assignee: Ellem Bioteknik ABInventors: Lars-Magnus Bjursten, Pentti Tengvall, Ingemar Lundstrom

Patent number: 5118401Abstract: Apparatus for applying a disinfectant solution which may include hydrogen peroxide, a salt and a buffer to an instrument wherein the instrument can be inserted into an opening in the wall of a vessel containing a disinfectant normally at a level below the opening. A floatation plunger is urged downwardly to displace the disinfectant to a level in engagement with the instrument and the electrodes are energized to activate the disinfectant. A magnetic latch holds the floatation plunger in place during disinfection and the disinfectant level is sensed to enable energization of the electrodes only when the level is sufficient to engage the instrument.Type: GrantFiled: June 4, 1990Date of Patent: June 2, 1992Inventors: Henry C. Oksman, Joseph Eisner
