Abstract: 본 발명은 관상동맥용 스텐트에 관한 것으로, 보다 상세하게는 스텐트의 형상을 유지하는 확장부재를 유연한 구조의 연결부재로 연결하여 스텐트의 유연성을 향상시켜 시술의 편의성을 향상시키며, 확장부재의 말단에 복수의 원호가 형성되어 응력이 집중되는 것을 방지하여 혈관벽의 손상을 최소화시킬 수 있는 관상동맥용 스텐트에 관한 것이다.
본 발명에 따른 관상동맥용 스텐트는, 관공을 개방상태로 유지하기 위해 종방향으로 복수개가 배열되고 반경방향으로 확장이 가능한 환상의 확장부재와, 종방향으로 이웃하는 확장부재를 서로 종방향으로 연결하는 연결부재를 포함하는 관상동맥용 스텐트에 있어서, 상기 확장부재는 종방향으로 서로 평행한 복수의 직선부와, 이웃하는 직선부의 종방향의 양측 말단을 교대로 연결하는 연결부로 구성되며, 상기 연결부재는 그 일측 말단이 이웃하는 확장부재 중 하나의 직선부의 양단부 사이의 소정 위치에서 연결되고, 타측 말단이 이웃하는 확장부재 중 다른 하나의 직선부의 양단부 사이의 소정 위치에서 연결된 것을 특징으로 한다.-

Abstract: PURPOSE: A method for coating heparin on the surface of a stent is provided to maintain a blood clot coagulation effect by improving heparin attachment stability. CONSTITUTION: A method for coating heparin on the surface of a stent is as follows. A coating solution is prepared by adding EDC(1-Ethyl-3-(3-dimethylaminopropyl) carbodiimide hydrochloride) and NHS(N-hydroxysulfosuccinimide) to a mixture solution of heparin and dopamine. A metal stent is dipped in the coating solution. The metal stent is made of a material selected from a group consisting of stainless steel, Co-Cr alloy, tantalum, and gold.

Abstract: PURPOSE: A method for coating heparin on the surface of a stent is provided to improve the stability heparin on the surface of a stent based on the chemical bond of dopamine and the heparin. CONSTITUTION: A method for coating heparin on the surface of a stent includes the following: heparin and dopamine are synthesized, and a solution with the dissolved synthesized product is prepared; and the solution is applied on the surface of a metal-based stent such that the heparin is coated on the surface of the stent. The molar ratio of the heparin and the dopamine is 1:1.2-1.5. The coating process is based on an immersing process or a spraying process. The stent is immersed in the synthesized product dissolved solution, or the synthesized product dissolved solution is sprayed on the stent.
