摘要： A balloon dilation catheter comprises an outer tube (1), a reinforcing tube (2), a balloon (4), an inner tube (3) and a connector (6). The reinforcing tube (2) runs through the inner chamber of the outer tube (1). The distal end of the reinforcing tube (2) passes through the balloon (4), and is sealed with and fixed to the distal end of the balloon (4). A plurality of hollowed-out grooves (21) are provided in the reinforcing tube (2). The inner tube (3) runs through the inner chamber of the reinforcing tube (2). The distal end of the inner tube (3) protrudes from the distal end of the reinforcing tube (2), and is sealed with and fixed to the balloon (4). The connector (6) is fixed to the proximal end of the outer tube (1), and is provided thereon with a first connection port (61) and a second connection port (62). Compared with the existing reinforcing tube formed as a whole tube, the present balloon dilation catheter can change a bending angle automatically and flexibly to fit with blood vessels, thus reducing a damage to the blood vessels during delivery and withdrawal.
