| 摘要 |
A shape transformable medical implant or optical lens capable of substantial recoverable deformation in all dimensions is rapidly inserted and positioned into a target site such as an eye through an ejector having a small diameter, elongate, generally tubular outlet. The medical implant or optical lens is formed of a material having an elongation at break greater than 100% facilitating its ejection into the eye through a tubular outlet having an inner diameter of 3 mm or less. The ejector is provided with a precisely pressurizable chamber for the controlled displacement of the medical implant or optical lens through the small diameter, elongate, generally tubular outlet.
