Solution Group: Balloon Catheters
This 3-Up necker reduces the outside diameter of thermoplastic tubing. The tubing is heated to a temperature at which the yield strength of the material is significantly reduced. The dimensional change is then achieved by stretching the material in the axial direction. Common applications include: catheter journaling, heat shrink tubing sizing, polymer tubing delamination, and tubing sheathing (eg, wrapping SS hypotube shafts or wire braids with polymer tubing).
