What is radio frequency welded catheter tubing?
Radio frequency (RF) thermal heating, sometimes called high-frequency welding, bonds the molecules in two polymers into a uniform weld that is smooth and seamless. Medical device applications often include thermoplastic bonding of soft tips on catheter shafts and thermal reflowing of catheter terminations.
What are the advantages of RF-welded medical plastics?
RF welding of a catheter tube can create an impervious seal.
- Through RF welding, catheter tubing can be butt-welded together.
- RF welding has tight heat controls which provide repeatability.
Which materials or medical catheter components typically require RF welding?
- Any tube which requires a soft tip bonded to a catheter shaft could use RF technology.
- RF technology can be used for catheter tips that transition from a multi-lumen to a single lumen.
- Radio frequency welding can be used to create a tip shape or a specific geometric shape.
What is RF tipping?
RF welding, sometimes called high-frequency welding, can be applied to the formation of tips by bonding a softer tip to a more rigid catheter shaft.
