The present invention relates to a balloon catheter. The invention comprises: a first shaft; an expandable balloon which is attached to the front end of the first shaft; an expandable lumen which is formed inside the first shaft and to which a liquid required for expanding the balloon is provided; a second shaft which extends from the front end of the first shaft to which the balloon is attached and has a wire hole through which a guide wire passes; and a guide wire lumen, which is formed inside the second shaft and through which the guide wire passes. According to the invention, the first and second shafts are coaxially connected and the expandable lumen and the guide wire lumen are respectively formed in each shaft in order to reduce the overall diameter of the shaft, thereby facilitating surgery and improving pushability.

Balloon catheter

A system and method for providing an image capable of realizing conversion of a 3D tissue structure into which an implant is inserted into a 2D image using a contour technique are provided. The system for providing an image includes an imaging unit configured to photograph an inner part of a blood vessel into which an implant is inserted to provide a plurality of tomographic images, a first analysis unit configured to analyze the plurality of tomographic images to generate data on strut distribution of the stent, a second analysis unit configured to analyze the plurality of tomographic images to generate data on a thickness of a neointima, a first image generation unit configured to generate a strut distribution chart of a 2D image using the data on the strut distribution, a second image generation unit configured to generate a contour map for the thickness of the neointima using the data on the thickness of the neointima, and a composition unit configured to composite the strut distribution chart and the contour map.
