Isolation and focal treatment of brain aneurysms using interfacial fluid trapping. | LitMetric

AI Article Synopsis

  • Current localized intravascular treatments usually involve solid implants or therapeutic injections, which can spread beyond the target area.* -
  • This new technique uses fluids and their surface tension to specifically target and treat brain aneurysms by positioning a separate fluid phase at the aneurysm's neck.* -
  • The method has been validated through computer simulations and experiments, showing successful localized delivery and treatment without affecting surrounding areas, making it a promising option for cardiovascular treatments.*

Article Abstract

Current approaches for localized intravascular treatments rely on using solid implants, such as metallic coils for embolizing aneurysms, or on direct injection of a therapeutic agent that can disperse from the required site of action. Here, we present a fluid-based strategy for localizing intravascular therapeutics that leverages surface tension and immiscible fluid interactions, to allow confined and focal treatment at brain aneurysm sites. We first show, computationally and experimentally, that an immiscible phase can be robustly positioned at the neck of human aneurysm models to seal and isolate the aneurysm's cavity for further treatment, including in wide-neck aneurysms. We then demonstrate localized delivery and confined treatment, by selective staining of cell nuclei within the aneurysm cavity as well as by hydrogel-based embolization in patient-specific aneurysm models. Altogether, our interfacial flow-driven strategy offers a potential approach for intravascular localized treatment of cardiovascular and other diseases.
