- Porous media properties of reticulated shape memory polymer foams and mock embolic coils for aneurysm treatmentAndrea D Muschenborn
Texas A and M University, 3120 TAMU, 77843 College Station, Texas, USA
Biomed Eng Online 12:103. 2013..The purpose of this study is to experimentally determine the parameters, permeability and form factor, which are related to the flow resistance imposed by both media when subjected to a pressure gradient...
- Virtual treatment of basilar aneurysms using shape memory polymer foamJ M Ortega
Engineering Technologies Division, Lawrence Livermore National Laboratory, P O Box 808, L 090, Livermore, CA 94551, USA
Ann Biomed Eng 41:725-43. 2013..The Newtonian viscosity model and the porous media model capture similar qualitative trends, though both yield a smaller volume of thrombus within the SMP foam...
- Vascular dynamics of a shape memory polymer foam aneurysm treatment techniqueJason Ortega
Engineering, Lawrence Livermore National Laboratory, P O Box 808, L 644, Livermore, CA 94551, USA
Ann Biomed Eng 35:1870-84. 2007..Beneath the aneurysm neck, a marked increase in the wall shear stress is observed due to the close proximity of the counter-rotating vortex tubes to the artery wall...
- A shape memory polymer dialysis needle adapter for the reduction of hemodynamic stress within arteriovenous graftsJason M Ortega
Lawrence Livermore National Laboratory, Livermore, CA 94551, USA
IEEE Trans Biomed Eng 54:1722-4. 2007..Both the simulations and the qualitative flow visualization measurements demonstrate that the adapter reduces the severity of the dialysis needle flow impingement on the vascular access graft...
