Title: MEDICAL DEVICE AND METHOD FOR MANUFACTURING MEDICAL DEVICE
Abstract:
The objective of the present invention is to provide a technology that provides a medical device with favorable operability. A catheter (100) comprises: a tubular main body (10) in which are formed a main lumen (20) and a sub-lumen (80) which is disposed around the main lumen (20) and extends along a longitudinal direction of the main lumen (20); and an operating line (70) which is disposed inside the sub-lumen (80) and a distal end of which is fixed to a distal end of the tubular main body (10). The operating line (70) is circular in a cross section orthogonal to the longitudinal direction or the operating line (70) is a stranded wire composed of multiple filaments which are circular in a cross section orthogonal to the longitudinal direction. The cross sectional shape of the sub-lumen (80 (80a, 80b)) orthogonal to the longitudinal direction is a flat shape which is flat in a circumferential direction of the main lumen (20).
