Abstract: Herein is described a stent platform capable of intravascular local delivery of therapeutics through multipoint injection of drug agents into the vascular walls and endocardial surfaces. More specifically, an endovascular injectable stent made of kirigami skin is wrapped around a soft linear actuator and used for intravascular local drug delivery of therapeutics. This platform addresses an unmet need of treating aortic stenosis and atherosclerotic cardiovascular disease.

Abstract: A computer-implemented method for diagnosing a medical condition of a patient is provided. The method can include causing, using one or more processors, an excitation source to emit an excitation light towards a region of interest of an artery, receiving, using the one or more processors and a detector, imaging data of the region of interest of the artery, generating, using the one or more processors and the imaging data, an image of the region of interest, determining, using the one or more processors, a risk region of an atheromatous plaque, based on the imaging data, and determining, using the one or more processors, that the patient has a severe case of an atheromatous plaque, based on the determined risk region of the atheromatous plaque.

Abstract: Provided herein are peptide amphiphiles (PAs). In some embodiments, provided herein are targeting PAs comprising a PA backbone and a targeting moiety. In some embodiments, provided herein are therapeutic PAs comprising a PA backbone and a therapeutic agent. In some embodiments, the peptide amphiphiles are co-assembled into nanofibers. In some embodiments, the nanofibers may be used for the treatment of atherosclerosis or related disease.
