CONFLUENT HB-700 View Large Image

Confluent's Hot Air System (figure 1) is a compact, bench-top system designed to provide a precisely controlled stream of hot air. Different shapes and sizes of air nozzles are available to deliver a focused jet of temperature controlled air to a desired spot. The most often encountered applications for this device are heat fusing, heat shrinking, and shaping operations performed during the catheter manufacturing process.

The HB-700 allows for the precise setting of air temperature and air flow. To achieve the most accurate temperature reading, a miniature thermocouple is installed in the air stream, 1 millimeter from the nozzle exit. Optional “bolt-on” attachments are available for catheter tipping and conversion bond (Rx bond) fuse-welding, e.g., fuse-welding proximal-to-distal shafts and fusing the distal shaft/inner lumen junction, shaping the balloon neck-to-shaft transition, etc. These devices substantially increase the utility and production yields achieved with the Hot Air System.
