bring healthcare devices to market faster

In 2019, Willow partnered with Infostretch to deliver on the digital technology aspect. This included the development of a companion mobile application with firmware testing and verification. Infostretch employed a “blitzscaling” approach to deliver the project within six months, developing a complete device firmware protocol test framework. In addition, Infostretch provided end-to-end mobile application design and development, as well as application automation framework design and development.

The challenge

TO develop new functionality

  • The Willow Wearable Breast Pump is a Class C medical device subject to strict FDA compliance requirements. In addition to the physical breast pump designed and manufactured by Willow, each of the software and messaging components also had to be developed with functionality and performance fully verified before and after the breast pumps were manufactured. In some cases, Willow was testing functionality that had never been developed before. There were a variety of difficult technical challenges which needed to be addressed in a timely manner, all within tight FDA compliance requirements.

The Solution
Working as a team

Infostretch started by conducting a thorough analysis of Willow’s functional and application architecture requirements and developed a proof of concept to confirm all QA automation requirements.

From there, the scope of Infostretch’s engagement included a combination of digital engineering and quality engineering. A ten member multifunctional Infostretch POD worked with Willow in four phases – Discovery, Development & Integration, Verification & Validation, and Implementation & Production Set-up.

The outputs from this effort included:

Companion Mobile Application Development

  • Android and iOS Applications
  • QA Automation Framework for Mobile Applications

This included both the application layer and wireless interfaces. Infostretch handled the development of all functionality for both Android and iOS applications, as well as the automation of testing for all application functionality on both operating systems.

Development & QA of the BLE Communication Interface
