Embolic compositions comprising macromers having a backbone comprising a polymeric backbone comprising units with a 1,2-diol or 1,3-diol structure, such as polyvinyl alcohol, and pendant chains bearing crosslinkable groups and, optionally, other modifiers. When crosslinked, the macromers form hydrogels having many properties advantageous for use as embolic agents to block and fill lumens and spaces. The embolic compositions can be used as liquid embolic agents and crosslinked in situ or as preformed embolic articles, such as microspheres.

Embolic compositions

A prosthetic spinal disc nucleus pulposus formed from a hydrogel formed by crosslinking a macromer having a polymeric backbone comprising units with a 1,2-diol or 1,3-diol structure and at least two pendant chains bearing crosslinkable groups and an amphiphilic comonomer.

Spinal disc nucleus pulposus implant

Hydrogel biomedical articles formed from macromers having a polymeric backbone comprising 1,2-diol and/or 1,3-diol units, such as polyvinyl alcohol, and pendant chains bearing crosslinkable groups and, optionally, other modifiers.

Hydrogel biomedical articles

Compositions comprising macromers having a backbone comprising units having a 1,2-diol and/or 1,3-diol structure for tissue bulking and coating. Such polymers include poly(vinyl alcohol) (PVA) and hydrolyzed copolymers of vinyl acetate, for example, copolymers with vinyl chloride, N-vinylpyrrolidone, etc. The backbone polymer contains pendant chains bearing crosslinkable groups and, optionally, other modifiers. When crosslinked, the macromers form hydrogels having many properties advantageous for use as agents to bulk and coat tissues.
