Contour™ PVA Embolization Particles
The Contour PVA Embolization particles are small and irregular flakes of polyvinyl alcohol, which are used for permanent occlusion within a blood vessel. The Contour PVA Embolization Particles have been proven to be safe and effective in many clinical scenarios for decades.
How it works
Due to the irregular shape of PVA flakes, Contour PVA Embolization Particles are designed to occlude vessels with less material than uniform microspheres.
In a controlled, single-center study of 100 patients randomized to either Embosphere™ Microspheres or Contour PVA Embolization Particles, the authors concluded that no significant differences could be found in: frequency of incompletely infarcted leiomyomas, degree of improvement in symptom score, patient satisfaction, or quality of life.1
A little volume can make a big difference
