Septal Closure Device, Olivia N. Welch, Hillal H. Jarrar, Kai Harrison
Biomedical Engineering
The septal closure device was designed to seal defects in the atrial septum. To fully seal an atrial defect, the device was designed to consist of two circular seals to cover the defect in both the right and left atria, attached with a central rod. The materials were chosen for compressibility (for ease of insertion), biocompatibility, and tissue ingrowth. A CAD model was drafted in SolidWorks. Key customer requirements include ease of implantation (specifications: adjustable sizing and clear directions for use), physician controlled (specifications: short implantation time and compatibility with current catheter/scope techniques), and a long lifetime (specifications: materials that …
Enhancement Of The Syncardia Total Artificial Heart For Pediatric Use, Margaret Clark, Madison Marks
Enhancement Of The Syncardia Total Artificial Heart For Pediatric Use, Margaret Clark, Madison Marks
Williams Honors College, Honors Research Projects
Pediatric patients with disorders and diseases of the heart have limited options with regards to implantable devices. Many of these implants are ventricular assist devices, which is not always suitable for a patient. Total artificial hearts (TAHs) have supported many adult patients until transplantation, and we believe that they could do the same for pediatric patients. SynCardia has the only Food and Drug Administration (FDA) approved TAH devices. Since SynCardia is the only company with FDA approved TAHs, we decided to modify the design of the SynCardia TAH for use in pediatric patients without compromising the function of the current …

Vector Flow Imaging In Pediatric Cardiology - Extracting And Validating Data, Mason Belue
Biomedical Engineering Undergraduate Honors Theses
In the field of bedside cardiac diagnostic imaging, Doppler Ultrasound (DU) is the gold standard for diagnosing heart conditions. The largest benefit of DU is its ability to noninvasively image cardiac flow and allow the estimation of blood velocity and quantification of anatomical disease. However, to get correct velocity estimation, the position of the transducer in relation to the flow field needs to be known. This is the problem of angle/direction dependency and limits DUs accuracy when imaging in areas where perfect alignment or exact position of the transducer in relation to flow field is not possible or known, such …

Dynamic Model For Simulating Motion Of The Right Ventricle, Brian Michael Larsen, Sam Koopman Porter, John Francis D'Ambrosio
Mechanical Engineering
This report documents all the research, ideation, and mockups used to determine right ventricle motion and develop a system capable of reproducing that motion on a tissue sample. The model is intended for evaluating anchoring systems being developed by Edwards Lifesciences for use with tricuspid valve therapies. Several design solutions were considered for the primary functions of recreating motion of the right ventricle and attaching tissue to the device. From these ideas a primary means of producing motion and attaching tissue was selected. These ideas were then developed over the course of a school year to become the final system …
