First Claim
Patent Images
1. A method of manufacturing a three-dimensional scaffold using an apparatus for electrospinning comprising a high-voltage power supply;
- at least one spinneret connected to at least one container comprising a solution with at least one polymer dissolved therein; and
a collector, wherein said method comprises;
forming crystals from a molecule or group of molecules in vapor phase comprised in the surrounding atmosphere at the surface of said collector, wherein said collector has a temperature which allows formation of crystals at said surface of said collector;
electrospinning said solution comprising at least one polymer dissolved therein around said crystals;
continuing said formation of crystals and said electrospinning simultaneously; and
removing said crystals by sublimation.
