摘要： Provided is a synthetic resin stent that has resistance to pressure externally applied from the radial direction while in an enlarged diameter state even when the synthetic resin fibers are thin. The synthetic resin stent comprises: a stent main section that is formed by synthetic resin fibers into a cylinder and that can deform from a reduced diameter state to an enlarged diameter state; and a restricting mechanism that keeps the stent main section in the enlarged diameter state by restricting the stent main section from reducing in diameter when in the enlarged diameter state. The synthetic resin stent preferably further comprises a diameter enlarging mechanism that is connected to the stent main section and that deforms the stent main section from a reduced diameter state to an enlarged diameter state.

摘要： Provided is a use for a peptide in surface-treating a medical device or medical material to be used in contact with blood, with which it is possible to obtain a medical device or medical material that can achieve highly efficient vascular endothelialization through the use of a peptide uniquely binding to vascular endothelial cells. Also provided are: a peptide suitable for use in said surface treatment; a method for producing a medical device or medical material surfaced-treated with said peptide and to be used in contact with blood; and a surface treatment agent including said peptide, said agent to be used in surface-treating a medical device or medical material to be used in contact with blood. In the present invention, a medical device or medical material is surface-treated using a peptide that includes any one of ten specific amino acid sequences and uniquely binds to the surface of endothelial progenitor cells.
