Abstract
A shape memory material-based minimally invasive implantation with end part self-expanding structure, and an implant having the structure. The implant includes an actuating component; the implant has a first shape and a second shape, and comprises a central part and multiple end parts which are substantially symmetrically distributed; the second shape has a larger area than the first shape; the actuating component is able to enable the end parts to move along a direction away from the central part of the implant, so that the implant is transformed from the first shape to the second shape. The present invention can allow an implant to have a small size before it is implanted and to be expanded into a structure having a larger size after implantation.
