Micro-abrasive blasting is a simple, yet highly effective, method to clean, cut, deburr, or texture a wide variety of surfaces. Micro-abrasive blasting with sodium bicarbonate media is currently being used in catheter manufacturing to remove polymer coverings from small selected areas and to remove PTFE coatings from catheter guidewires. Heel burrs formed during the tube grinding process, as well as holes or slots that are laser machined in the tubing can be deburred by micro-abrasive blasting. Selective texturing of the tube surface can be accomplished prior to over-molding and light abrading can impart an echogenic or etched surface finish.
