Cystic Fibrosis Therapy Device Uses Voice Coil Technology to Improve Mobility

In this episode of MedDevice by Design, Mark Drlik and Ariana Wilson share the story behind a novel cystic fibrosis therapy device that transformed a cumbersome hospital-grade system into a lightweight, wearable solution. The innovation journey begins with a prototype and ends with the Hillrom Monarch system—a commercially available device that enhances patient quality of life.

From Pneumatics to Portability

Traditional chest wall oscillation therapy for cystic fibrosis patients involves large pneumatic generators and bulky vests. While effective, these systems are noisy and restrict movement, making them challenging for home use. To address this, Mark and his team developed a new solution based on voice coil technology—a compact, precise, and quiet alternative.

Instead of relying on air-driven percussion, the redesigned device uses voice coils to deliver targeted chest wall oscillation. Patients can move freely while receiving therapy, improving both comfort and adherence.

How It Started: Prototype to Product

The project began when innovator Martin DeVlieger brought an early concept to StarFish Medical. The team refined the idea through engineering design, prototyping, and collaboration. Eventually, the technology was acquired by Hillrom and became the Monarch Airway Clearance System—now making a real impact in the lives of people with cystic fibrosis.

Why This Matters for MedTech

This episode highlights the importance of user-centered design in creating therapy devices that truly meet patient needs. It also underscores the value of strategic partnerships in bringing groundbreaking innovations to market.

Whether you’re an engineer, entrepreneur, or caregiver, this story offers insight into the development of cystic fibrosis therapy devices that combine technical performance with everyday usability.

A bold caption in the upper center reads "Bone or not?" and a red curved arrow points from the text to the knee with the implant, emphasizing the contrast between natural bone and artificial joint.

In this episode of MedDevice by Design, Ariana and Mark dive into the biomechanics and materials science behind osseointegration for implants.

On the right, the same eye is enhanced with a futuristic digital overlay of concentric circles and interface elements, suggesting advanced vision restoration technology. A red curved arrow points from left to right, implying improvement. Bold text at the top reads "Restoring Vision?"

Ariana and Mark explore how accommodative intraocular lens technology may one day restore natural vision for people who require cataract surgery or suffer from presbyopia. As Mark shares, traditional bifocals are not ideal, and new lens solutions may offer better outcomes.

Mark and Ariana explore the surprising versatility of barium sulfate—a material used widely in both diagnostic procedures and medical device manufacturing. While many recognize it as the contrast agent you drink before an X-ray, it’s also a key additive that enhances plastic components across the healthcare industry.
