One embodiment of the present invention discloses a method for manufacturing a microcatheter, which comprises the following steps: generating blood vessel information comprising a three-dimensional geometry of a blood vessel and an aneurysm of a patient； selecting target blood vessel information including a three-dimensional geometry of a target vessel of a patient connected to an aneurysm and an aneurysm among the blood vessel information； extracting a three-dimensional centerline of the target blood vessel and the aneurysm of the patient by analyzing the target blood vessel information； and generating a three-dimensional enlargement centerline through three-dimensional enlargement of the three-dimensional centerline. The present invention aims to provide the method for manufacturing the microcatheter, which can be used to implement a formation model of the microcatheter optimized for the blood vessel of the patient.본 발명의 일 실시예는 환자의 혈관 및 동맥류의 3차원적 기하구조를 포함하는 혈관정보를 생성하는 단계와, 혈관정보 중 동맥류와 동맥류에 연결된 환자의 표적혈관의 3차원적 기하구조를 포함하는 표적혈관정보를 선별하는 단계와, 표적혈관정보를 분석하여 환자의 표적혈관 및 동맥류의 3차원적 중심선(centerline)을 추출하는 단계와, 3차원적 중심선을 3차원 확대(three-dimensional enlargement)하여 3차원적 확대 중심선을 생성하는 단계를 포함하는 미세도관 제조 방법을 개시한다.
