Laser Drilling

Laser drilling is an ablation process that uses a focused laser beam to create micron-scale thru-holes on a wide variety of materials, including metals, polymers, and glass. The process is precise and efficient, enabling the fabrication of holes down to single microns in diameter. Our laser drilling eliminates heat damage during processing which maintains the integrity of the material.

Drug Delivery Balloons

Holes are laser drilled into catheter balloons for localized drug delivery in minimally invasive procedures. A significant challenge in this manufacturing process is that the geometry and surface of the balloon can vary from part to part. To solve this problem, our engineers have developed a patent process control method for on-line, automated vision mapping of the balloon geometry. A proprietary algorithm then makes real-time adjustments for the variation and ensures that the holes are placed in the correct locations every time.

Multi-Lumen Drug Delivery Catheters

Multi-lumen catheters are used to deliver drugs to specific areas through small satellite lumens. To be successful, small holes or an array of holes must be drilled through the outer wall of the satellite lumen without perforating the inner wall. To solve this challenge, our engineers developed a proprietary laser drilling process that incorporates an in-process optical inspection to detect inner wall damage as an end-point detection control method to prevent excessive ablation of the lumen inner wall.

Laser Drilling Applications

Laser drilling enables engineers to achieve highly repeatable drilling solutions at microscopic scales without error for a variety of applications, including:

  • Embolic protection filters
  • Access and side ports in infusion catheters
  • Micro hole arrays
  • Flow access holes
  • Drug delivery balloons
