Abstract
Injectable biopolymer compositions and associated systems and methods are disclosed herein. In some embodiments, a biopolymer composition for treating an aneurysm is provided. The biopolymer composition can include an injectable hydrogel including: a biopolymer; a chemical crosslinker forming covalent bonds with the biopolymer; and a stabilizer configured to inhibit ex vivo precipitation of the biopolymer. The injectable hydrogel can have an ex vivo storage modulus of at least 100 Pa at 37° C. over a linear viscoelastic region of the injectable hydrogel. The ex vivo storage modulus can be greater than an ex vivo loss modulus of the injectable hydrogel over the linear viscoelastic region of the injectable hydrogel.
