Abstract

A catheter system comprising a catheter including a tip having a distal opening, a first opening, and an insertion wire lumen extending from the distal opening to the first opening provided on a surface of the catheter, and an insertion wire having a length substantially smaller than a length dimension of the catheter. The catheter system in accordance with the present invention may include a sensor lumen and a pressure lumen. The sensor lumen terminates at a second opening and includes an optically transparent closure and the pressure lumen includes a third opening. In the preferred embodiment, the first opening and the second opening are positioned on the catheter at substantially same axial distance from the distal opening and further includes a perforation that allows fluidic communication between the pressure lumen and the second opening. The catheter system may also comprise a pressure hose, at least one optical fiber and a thermal sensor element. Furthermore, the catheter system may further comprise a three-way valve, a pressure transducer, a flushing valve, a flow controller, and a drip chamber.
