Resonetics Awarded US Patent for Laser-Based Micromachining of Conical Surfaces

August 10, 2010 – 8:39 am

This medical balloon has been processed by means of laser microdrilling equipment.

The US Patent and Trademark Office has allowed one of Resonetics‘ patent applications directed to laser micromachining of a conical surface.

This patent enables the laser-based microdrilling of holes as small as 1 µm in diameter and trimming of medical balloons or other 3-D geometries with high precision by means of an efficient volume manufacturing technique. This method is critical to meet the cost and yield demands of emerging device technologies such as drug eluting balloons, embolic protection, PTCA/PTA and kyphoplasty, according to Resonetics.

A supplier of laser micromachining equipment and contract services, Resonetics has developed 9 axes technology to permit the laser micromachining of complex, nonplanar 3-D polymer-based devices. Machining devices with a nonplanar geometry where the the surface curvature is continuously changing in the axial direction represents a significant technical challenge. Moreover, the surface curvature or cone angle is not constant, so simple fixturing techniques are not applicable.
