Abstract
The present invention relates to a rapid exchange or single operator exchange catheter device comprising at least one elongated tubular member having an inner surface and an outer surface, a proximal and a distal end, and having an opening located between the proximal and the distal end. The inner surface of the elongated tubular member defines a guide member lumen and is at least occasionally subjected to contact with at least one guide member. The guide member lumen, including the opening or port for receiving the guide member, are filled with the lubricious material in accordance with the present invention. This method of filling the lumen eliminates the need for flushing the catheter device before and/or during surgical procedures to remove air and contaminants and provides a lubricant for easy maneuvering of the catheter over the guide member.
