Over 80,000 microholes drilled in polyimide sheets create molds to fabricate less invasive endoscopic tool.
Potomac Photonics has recently fabricated micro-parts to be used on a project to develop new techniques for diagnosing and treating gastrointestinal diseases. Utilizing advanced precision micromanufacturing technologies, Potomac drilled over 80,000 blind holes in a polymer material. These holes were about 70 microns deep and had diameters between 110 and 140 microns.
Levin Sliker a National Science Foundation Graduate Research Fellow at the University of Colorado, Boulder describes the work:
“I work in the Advanced Medical Technologies Laboratory (AMTL), where we are developing a robotic capsule endoscope (RCE) which is capable of mobility within the gastrointestinal tract. We use micro-patterned polymers to enhance traction between the robot’s mobility system and the surrounding tissue. Potomac Photonics produces micro-drilled polyimide sheets that we use as molds to fabricate the micro-patterned polymers. Development of an RCE would yield a less invasive diagnostic and therapeutic tool when compared to traditional endoscopic methods. Potential applications of an RCE include diagnostic imaging, drug therapy, and biopsy. The micro-patterned polymer samples are also used in various experiments as part of an effort to develop a complete understanding of the contact mechanics between a micro-structured surface and a viscoelastic tissue substrate.”
This work was performed under Potomac Photonics’ Education Manufacturing Initiative, which is geared toward partnering with Universities to help with micromanufacturing applications at reduced costs. Mike Adelstein, President of Potomac says, “We are deeply committed to partnering with students and researchers to help develop new technologies by providing them with cost-effective advanced manufacturing technologies.”
