MEDICAL IMPLANTS OF STRETCH-CRYSTALLIZABLE ELASTOMERS AND METHODS OF IMPLANTATION |
摘要 |
<p>Reduced trauma medical implants and methods for their use are disclosed wherein at least a portion of the implant is formed of a stretch-crystallizable elastomeric material formulated to exhibit the property of stretch crystallization upon substantial elongation of the implant to form stable, small-incision implant configurations having at least one dimension substantially reduced for insertion through a surgical incision that is small relative to the incision size necessary to implant the unstretched implant. Exemplary embodiments include intraocular implants formed of optically clear, high refractive index stretch-crystallizable silicone elastomers formulated to stretch crystallize at near ambient temperatures upon elongations greater than or equal to 300% and to recover their original configuration immediately upon exposure to body temperature following implantation.</p> |
