Title: Method of producing structures using centrifugal forces
Inventor: SHOICHET MOLLY S
IPC: A61B17/11
Filed: 2001-05-11
Abstract: A variety of hollow structures with unique morphologies were manufactured with a rotational spinning technique. Phase separation of soluble solutions was induced within a filled mold as it was being rotated about one of its axis. As phase-separation occurs within this rotating mold, the increase in density of one phase results in sediment at the periphery under centrifugal forces. After or during sedimentation, gelation of the phase-separated particles fixes the tube morphology and the solvent remains in the center of the mold. The solvent is removed from the mold resulting in a tube. By controlling the rotational speed and the formulation chemistry, the tube dimensions and wall morphology can be manipulated. This technique offers a new approach to the manufacture of polymeric tubes. It requires small quantities of starting material, permits multi-layering of tubes, is applicable to diverse polymers and can result in highly diffusive hollow structures while maintaining good mechanical strength.
