title: [Design and experimental application of a device for direct vision intracardiac operation without cardiopulmonary bypass].
abstract: OBJECTIVE
  To design a device for direct vision intracardiac operation without cardiopulmonary bypass, and assess its applicability preliminarily.
  
  
  METHODS
  The device was designed according to the clinical needs of intracardiac operation and used in operations for repairing atrial septal defect in 5 ex vivo porcine heart models. The practical applicability of this device was thoroughly tested and the results of the operations were evaluated.
  
  
  CONCLUSIONS
  Direct vision operation for repairing atrial septal defect was successfully performed using this device, which can be a well applicable in some intracardiac operations, but its clinical effects need further evaluation.
