Are you responsible for fast-tracking Class III device development? Designing microfluidic instruments? Incorporating more sensors in a smaller package? We can help you with that, and more. We’ll meet your requirements for the use of FDA-approved Class III materials and manufacturing processes. Provide documentation packages that include material traceability (incoming inspection and documentation), along with part/substrate serialization. No matter whether you need to assemble a few beta units, low volumes of less than 100 units a year, or are ready to scale to high volumes, we have the engineering experience and specialized equipment to get it done.
Automating custom processes for unique medical devices is our specialty
Many medical products require the use of organic materials such as adhesives to join parts, encapsulants to seal parts, coatings to prevent contact and to provide isolation. These organics are deposited in a variety of manual or automated dispensing methods requiring precision and control that only a highly experienced technician can provide.
Unique devices also often have equally unique production requirements such as not exceeding 85° C during assembly, or handling die that cannot be exposed to cleaning processes. Fluid processing devices in particular require excellent adhesion between surfaces and elimination of voids or bubbles in organics. No matter how unique your requirements, we can specify the best materials, cleaning processes and surface preparation to avoid leakage and ensure stable performance.
“As the Spinal Modulation implantable neuro stimulator project comes to an end, I want to take this opportunity to recognize the contribution of the Promex team. Promex was our partner in development and manufacturing from early in the program. Their contributions were a big part of the success of the program. We recognize that the low volume and critical application of an active implantable medical device is a formidable challenge for a contract manufacturer. We appreciate Promex’s willingness and success at rising to this challenge. I would personally like to thank the many people that touched this program. Their personal commitment to quality did not go unnoticed.”
— Spinal Modulation Director of Manufacturing Engineering Steve Schellenberg
