Abstract
A medicinal liquid injection catheter includes a flexible main body, a needle-like tubular member, a medicinal liquid supply device, and a balloon. The tubular member is inserted in the main body and an end portion of the tubular member projects from a side hole provided in the main body. The medicinal liquid supply device accommodates a medicinal liquid, and is connected to the tubular member to supply the medicinal liquid through the tubular member. The balloon is attached to an outer portion of the main body and the balloon is expansible in substantially the same direction as a direction in which the portion of the tubular member projects. The medicinal liquid injection catheter additionally includes first and second guide wires. The second guide wire projects from the main body in a direction which intersects a direction in which the first guide wire projects from the main body.
