Segmented Therapeutic Delivery via Acoustic Microbubble Relay

Lei Wang, Yiyang Tang, Yiqiang Wu, Xin Zhang et autres

Conventional medical microcatheters, characterized by their stiff, continuous hollow tube design, encounter inevitable mechanical constraints when delivering therapeutic agents through tortuous, highly curved, and narrowing microvascular networks. To overcome this constraint, we introduce an acoustic microbubble‐powered segmented delivery system. This microdevice utilizes …
