A trocar assembly for providing a pressurized insufflation fluid into a patient cavity and for providing sealable access to the patient cavity by a surgical instrument. The assembly comprises an inner tubular member having a proximal end and a distal end. An outer tubular member is disposed about the inner tubular member, the outer tubular member having a proximal end and a distal end. The distal end of the inner tubular member and the distal end of the outer tubular member define a trocar seal nozzle arranged therebetween.
