ABSTRACT:
A catheter for performing various medical procedures, such as coronary angiography or angioplasty. The catheter has an elongated, tubular, inner wall, enclosing a central lumen. An elongated, tubular, outer wall encloses the inner wall and a minor lumen between the inner and outer walls. A side hole passes through the outer wall, but not through the inner wall. Therefore, when the catheter is inserted into a coronary artery, blood can perfuse through the side hole and the minor lumen, without affecting the functions of the central lumen.
