Abstract
A catheter device having an elongated tubular member with a proximal end and a distal end, and a needle disposed near the distal end. In one embodiment, the needle has a rigid, penetrating tip coupled to a flexible portion by an overlapping joint. The flexible portion enables the needle to bend to a penetrating angle relative to the distal end of the elongated tubular member and penetrate a body tissue without kinking.
