Figure 5

As a result of local fluid dynamics around a cavitating microbubbles, the fibrinolytic enzymes (recombinant tissue-plasminogen activator (rt-PA) and plasminogen) penetrate deeper into the fibrin matrix. Additionally, fluid microstreaming removes fibrin degradation products from the surface of the clot, expediting the fibrinolytic process.
