SURVAC™ are atraumatically rounded single use suction catheters for bronchoscopy. The PTFE-catheters are more flexible than the polycarbonate (PC) catheters. Due to their flexibility and their small diameter, the PTFE-catheters are adapted to suctioning more distal parts of the tracheobronchial tree. The larger (3 x 4 mm) polycarbonate catheters are particularly suited for the axial aspiration of larger tumor parts or suctioning of large quantities in emergency cases.
