Caltech-Led Team Develops Ultrasound-Enabled 3D Printing Inside Living Bodies

Canadian-designed ultrasound helmet may revolutionize the way ALS is treated

Canadian researchers have launched a world-first study to fight ALS in an entirely new way, using a specially designed helmet that delivers medication into the brain using low-dose ultrasound.

Health Rounds: Ultrasound triggers experimental 3D drug-delivery implants

(Reuters) – (This is an excerpt of the Health Rounds newsletter, where we present latest medical studies on Tuesdays and Thursdays) Ultrasound waves can penetrate through thick tissues and print medical implants inside a body, experiments in animals suggest. Researchers created 3D implants using focused ultrasound and ultrasound-responsive bioinks delivered via injection or catheter. The carefully guided ultrasound waves trigger localized heatin…

3D printing in vivo using sound

New technique for cell or drug delivery, localization of bioelectric materials, and wound healing uses ultrasound to activate printing within the body.

In vivo 3D printing using sound holds promise for precise drug delivery, wound healing and more

Imagine that doctors could precisely print miniature capsules capable of delivering cells needed for tissue repair exactly where they are needed inside a beating heart.

Caltech team 3D-prints drug depots inside living tissue

Caltech engineers have turned focused ultrasound into a noninvasive “printhead,” raising tissue temperature by only a few degrees to solidify injectable bio-inks several centimeters beneath the skin. The deep-tissue in-vivo sound-printing (DISP) technique shaped drug-loaded hydrogels next to mouse bladder tumors—killing more cancer cells than a direct doxorubicin shot—and built conductive gels inside rabbit muscle… The post Caltech team 3D-print…
