Patent ID: 8734388

Claim:
A medical apparatus for use during cardiopulmonary bypass surgery of a patient, comprising: a venting catheter comprising a flexible elongate shaft having a distal end, a proximal end, and an inner venting lumen, the proximal end including a valve assembly controllable between a vent port and a sealing wire valve, the inner venting lumen extending from the valve assembly at the proximal end to an inlet port at the distal end of the shaft and configured to withdraw blood from a pulmonary artery, the shaft having a length selected to allow the distal end to be positioned in the pulmonary artery with the proximal end extending transluminally to a central vein and out of the patient through a puncture in the central vein; a pacing wire disposed through the sealing wire valve and within said shaft and being movable axially therealong between a first, retracted position and a second, extended position; wherein the apparatus is insertable into the vasculature and heart of a patient for pulmonary venting in a venting mode, during which the pacing wire is within the venting lumen of the catheter tube at the first position, and for pacing of the heart in a pacing mode, during which the pacing wire is extended from the distal end of the shaft to the second position to engage intracardial tissue of the heart for pacing thereof.
