Patent ID: 7641646

Claim:
A catheter device comprising an elongate shaft, said elongate shaft comprising: a proximal end; a distal end; a first lumen extending through at least a portion of the shaft and defined by a wall; an aperture through the wall, open to the first lumen; said aperture disposed between the proximal and distal ends, the shaft including at least one continuous portion adjacent the aperture such that the proximal and distal ends include a continuous shaft between them; and an overlay disposed at least partially in the aperture, the overlay including an access port open to the first lumen, said access port being configured for passage of a wire guide therethrough, wherein an external diameter of the elongate shaft comprises a consistent external diameter along a shaft length from a region proximal of the overlay through a region distal of the overlay, such that the external shaft diameter along the overlay is no greater than the external shaft diameter immediately proximal of the overlay and immediately distal of the overlay.
