Patent ID: 8870572

Claim:
A method of implanting an implant in human or animal tissue, comprising the steps of: providing an implant comprising first material portions and second material portions, said second material portions being liquefiable by mechanical vibrations, the first material portions comprising a polymer having, in a non-modified state, a first glass transition temperature being equal to or greater than an implantation temperature, which implantation temperature is between 20° C. and a body temperature; bringing the implant in contact with tissue in a condition in which the second material portions are under an effect of a plasticizing agent, which reduces the glass transition temperature of the second material portions to a second glass transition temperature, below the first glass transition temperature; coupling mechanical vibrations into the implant while the implant is in contact with the tissue and the second material portions are at a temperature higher than the second glass transition temperature and thereby liquefying material portions of the first and second material portions of the implant; letting the liquefied material portions re-solidify; and subsequently or simultaneously or simultaneously and subsequently, causing the effect of the plasticizing agent acting on the second material portions to wear off.
