NIH-funded researchers have outlined a method to print biocompatible structures through thick, multi-layered tissues using focused ultrasound.

These structures had a range of sizes and geometrical intricacies and included objects such as multi-layer honeycomb, a branched vascular network, and complex models that resembled a hand or spider.
