Abstract
A biocompatible intelligent material capable of creating various shapes through remote foaming of a polymer is disclosed. The material may comprise a gas-containing polymer; and a restoring member that is at least partially embedded within the polymer, is heatable by electromagnetic induction, and returns to a memorized shape upon heating.
Claims15
A remote foaming material comprising:
- a gas-containing polymer that is configured to foam upon heating;
- and
- a restoring member at least partially embedded within the polymer, the restoring member comprising a material that is heatable by electromagnetic induction and that has a shape-memory property such that it returns to a memorized shape when heated.
A method for manufacturing a remote foaming material, comprising:
- a foaming-polymer preparation step of preparing a gas-containing polymer configured to foam upon heating;
- and
- a restoring-member embedding step of embedding a restoring member, which comprises a material heatable by electromagnetic induction and having a shape-memory property, such that at least a portion of the restoring member is embedded within the polymer.
A method for volume expansion and shape fixation using a remote foaming material, comprising:
- a first step of placing, bonding, or inserting a remote foaming material comprising a gas-containing polymer configured to foam upon heating and a restoring member at least partially embedded within the polymer and comprising a material heatable by electromagnetic induction and having a shape-memory property, at a target site;
- and
- a second step of heating the remote foaming material through electromagnetic induction to a temperature sufficient to induce foaming of the polymer and to cause the restoring member to return to its memorized shape.
