Biomorphic Programmable Polymers


Our proprietary biomorphic programmable polymers enable tissue reconstruction and can be adapted for use in multiple clinical areas


Conforms to and integrates with surrounding tissue to enable tissue reconstruction


Polymer building blocks can be adjusted to match tissue-specific requirements

Our polymer technology is based on the combination of safe, naturally occurring compounds, such as glycerol and sebacic acid.

A viscous pre-polymer can be precisely applied to tissues, with minimal displacement by body fluids, during surgical procedures.

The high viscosity of the pre-polymer allows it to be precisely applied with minimal displacement by body fluids.

The viscous pre-polymer is activated on-demand, within seconds, using a visible blue light

The resulting elastomeric bond ensures fixation, allowing the polymer to comply with the underlying tissue while remaining strongly fixed.

The pre-polymer can also be used as a resin to build high-resolution 3D-printed devices.

The pre-polymer can also be loaded with drugs and deployed potentially anywhere in the body, creating a depot that elutes drugs locally for extended periods.

Versatile applications

Tissue Sealants

We develop tissue sealants for use in cardiovascular procedures.

Tissue Fixation

We develop solutions for use in peripheral nerve and gastrointestinal procedures.

3D-Printed Implants

We design surgical scaffolds using 3D printing technology for peripheral nerve repair.

Localized Drug Delivery

We Formulate drug-eluting solutions for Tissue Repair.
