1. A catheter comprising:
- a tubular body having proximal and distal ends, and inner and outer surfaces;
at least one valve formed near the distal end of the tubular body, the valve including a deformation portion defining a slit, the slit communicating from the inner surface to the outer surface of the tubular body, wherein the distance between the inner surface and the outer surface of the tubular body progressively thins within the deformation portion in a direction toward the slit, the deformation portion being deformable to open the slit in response to a force exerted on the deformation portion from the inner surface of the tubular body, and the deformation portion being deformable in response to a force exerted on the deformation portion from the outer surface of the tubular body.

Abstract
A catheter including one or more bidirectional valves is provided. The catheter includes a tubular body having proximal and distal ends, and inner and outer surfaces, and at least one valve formed near the distal end of the tubular body. The valve includes a deformation portion that defines a slit that is openable and closable. The openable/closable slit communicates from the inner surface to the outer surface of the tubular body, wherein the distance between the inner surface and the outer surface of the tubular body progressively becomes thinner approaching the openable/closable slit within the deformation portion.
