Cleans Interior and Exterior of Capillary Tubes to Improve Flow of Fluid

This cleaning device for tubing used in stents, other medical devices, and flexible piping systems allows internal and external cleaning of capillary tubes to improve the flow of fluid. The worldwide market for stents, which are mesh tubes used to hold open arteries, is expected to grow to about $10.6 billion in 2019. The manufacturing process for the capillary tubes used in stents sometimes leaves behind imperfections in the tube walls that can impede the flow of fluid. A new finishing device developed by a University of Florida researcher can smooth the tube surface, making it more efficient.

Application

Device for finishing and cleaning capillary tubes for stents, other medical devices, and flexible piping systems

Advantages

  • Provides a unique competitive advantage by deburring metal residue inside tubes, minimizing problems associated with flow
  • Applies to other medical tubes and flexible piping systems, serving multiple markets

Technology

The device developed by a University of Florida researcher allows internal and external cleaning of capillary tubes with a system that uses a motor, chuck, jig, and magnet. The device also accomplishes deburring of the metal residue, which causes flow problems in available flexible capillary tubes. These tubes have slits in the wall for flexibility. In existing tubes, the superheating process that creates the slits can leave behind metal burrs on the inside wall that impede the flow of fluid through the tube. Removing burrs and cleaning the tube can improve flow of fluid. In this cleaning system, magnetic force applied to the tube causes abrasives to scrape the inside walls, cleaning off these burrs and other debris.
