Research presented at the Society of Interventional Radiology Annual Scientific Meeting in Boston supported the hydrogel, which was injected into spinal discs in an effort to relieve chronic low back pain caused by degenerative disc disease (DDD).

Researchers at the University of California, Riverside, are touting a polymer-based membrane as a potential drug delivery platform.
The researchers developed the membrane made from threads of a polymer commonly used in vascular sutures, according to the university’s website. The membrane can be loaded with therapeutic drugs and implanted in the body before its electric potential is activated by mechanical forces and the drugs are slowly released. The researchers published information on the system in ACS Applied Bio Materials.

European researchers have developed an injectable hydrogel that could help repair and prevent further heart muscle damage after a heart attack.
The therapeutic effect of multiple injections of this hydrogel into the cardiac tissue was assessed during the first preclinical study of its kind, demonstrating its efficacy for cardiac tissue remodeling following a heart attack, according to the researchers at CÚRAM, the SFI Research Centre for Medical Devices based at the National University of Ireland Galway, and BIOFORGE Lab, at the University of Valladolid in Spain. The results of their research have just been published in Science Translational Medicine.

Engineers at MIT are touting a medical patch capable of being delivered through narrow spaces to patch up internal injuries.
With inspiration from the art of origami, the engineers designed the patch to be folded around minimally invasive surgical tools and delivered through airways, intestines and other narrow spaces to patch up internal injuries, according to a news release.
The patch resembles a foldable, paper-like film when dry, the researchers said, and it transforms into a stretchy gel, like a contact lens, when it makes contact with wet tissues or organs, becoming capable of sticking to an injured site. The new tape is designed to resist contamination when exposed to bacteria and bodily fluids and it can safely biodegrade away, according to data published in Advanced Materials.
MIT researchers said they are working with clinicians and surgeons to optimize …
