Abstract
The disclosure provides methods for expanding a polymeric tube using one or more deformable members. The methods can involve disposing the polymeric tube within the one or more deformable members and radially deforming the polymeric tube and the one or more deformable members. The rate of deformation of the polymeric tube and/or the extent of deformation of the one or more polymeric tubes can advantageously be controlled along one or more axes by at least one of the one or more deformable members.
Claims21
A method, comprising:
- disposing a polymeric tube within a deformable member;
- and
- radially deforming the polymeric tube and the deformable member, wherein one or more of a rate of deformation of the polymeric tube and an extent of deformation of the polymeric tubes is controlled based at least in part on the deformable member,
- wherein the method provides an expanded polymeric tube exhibiting increased surface area or enhanced patterning relative to a comparable expanded polymeric tube produced by a different method;
- wherein the increased surface area or enhanced patterning comprises features to influence flow properties of adjacent fluid flow fields on an inner or outer surface of the expanded polymeric tube.
