Patent Ductus Arteriosus (PDA)





Ductus arteriosus (DA)
allows blood to bypass
pulmonary and enter
systemic
Usually DA closes within 1018 hrs of delivery (if not
deemed abnormal/patent)
PDA occurs in 1/2500-5000
live births
Many adverse effects
(growth retardation,
breathlessness or lack of
appetite
Most common problem is
congestive heart failure
1/15/2003
Current Treatments

Drug therapy
(indomethacin)
 Implantable devices
(most common are
coils)



Usually need 3-4 coils
Difficult to remove and
reposition
Invasive surgery (ligate
the PDA to inhibit blood
flow)

Project Goals
 To
design, develop and patent a PDA
occlusion device that can…
 Be
delivered via a catheter
 Conform to the shape of the PDA and
cause occlusion
 Can be repositioned
 Be cost effective (<$200)
 Provide an initial success rate of 100%

Our Design
1/15/2003
Current Status
 Conducted
extensive research on other
treatment methods (to avoid short
comings on our design)
 Design refinement finalization
 PDA Device prototype
 Design testing apparatus
 Making adjustments to website
1/15/2003
Needs
 Inquired
with multiple companies about …
 Biocompatible
and expandable foam
 Biocompatible memory wire
 Have
not received a response and thus are
seeking assistance from a biomaterials
expert
1/15/2003
Future Direction
 Build
a test device for the Patent Ductus
environment
 Conduct strength and pressure testing
 Refine design based upon testing
 Build scaled prototype with correct
biomaterials
 Talk with Dr. Doyle about patenting this
PDA Occlusion Device
