| titleOfInvention | Polylactic acid fiber reinforced intravascular stent and preparation method thereof |
| abstract | The invention provides a polylactic acid fiber reinforced intravascular stent and a preparation method thereof, wherein the intravascular stent is prepared from the following raw materials: the raw materials comprise polylactic acid fiber and a polylactic acid matrix; the polylactic acid fiber accounts for 0.5-80% of the raw material by mass; the melting point of the polylactic acid fiber is 210-240 ℃; the polylactic acid fiber is made of a compound formed by levorotatory polylactic acid and dextrorotatory polylactic acid; or the polylactic acid fiber is made of a segmented copolymer of levorotatory polylactic acid and dextrorotatory polylactic acid. The intravascular stent provided by the invention takes polylactic acid fiber and polylactic acid matrix as raw materials, the compatibility between the polylactic acid fiber and the polylactic acid matrix is good, and the strength of the stent is enhanced by the existence of the fiber. The polylactic acid fiber reinforced intravascular stent has the average tensile strength of 90-110 MPa; 30 test samples are tested during the adhesion test of the intravascular stent and the coating, and 28-30 test samples do not crack or fall off. |
