Project Definition Goals in February Goals in February Pick final project designPick final project design Begin patent search on chosen designBegin patent search on chosen design Project Goals Project Goals less costly / more simplistic occlusion device for an ASDless costly / more simplistic occlusion device for an ASD Develop a device that is easily sized to the ASDDevelop a device that is easily sized to the ASD Ensure ease use in the medical environmentEnsure ease use in the medical environment Ultimately improve the quality of life of the patient.Ultimately improve the quality of life of the patient.

Overall Project Status Research portion is near completion Research portion is near completion Final design decision pending advisor’s approval Patent search on the possible design models

Project Background What is a Ostium Secundum Atrial Septal Defect? What is a Ostium Secundum Atrial Septal Defect? congenital heart disease causes left to right shunting across interatrial septum Why should we care? Why should we care? Isolated secundum atrial septal defects of significance occur in approximately 70, ,000 individuals today. OSASD constitutes approx. 7-10% of all cases of CHD. 32,000 infants (one out of every 125 to 150)
