Andrews-Cooper has worked extensively across the design and engineering of this Class III medical device. Although we are not seeking work with any competitor to our key client in this area, we offer this information solely to demonstrate the range of capability we bring to any medical device firm and development project we work with.

The Philips HeartStart XL+ is a durable crash cart defibrillator and cardiac monitor.  Philips had already established an overall strategy for the look, feel and construction of the device.  Andrews-Cooper led the mechanical engineering of the device including a focus on several areas of the design that needed refinement.  This included a number of A-C personnel integrating their efforts with internal client efforts over a multi-year development effort.  The approach included:

  • Prototype: Several rounds of prototypes were built in order to make sure that the concepts met all the requirements with no surprises during detailed design.
  • Detailed Design: Detailed part design was completed for each component, making sure that the components that Andrews-Cooper was responsible for would work seamlessly with those designed by the clients internal engineers.
  • Review: Rigorous review sessions were held with the client’s engineering team as well as a multi-function team including suppliers, manufacturing and support personnel.  Designs were adjusted based on those reviews and then released for a prototype build using rapid-prototyped components. After the designs were proven by prototyping and testing, final design adjustments were made for part manufacturing.  Several large, complex injection molded parts were designed by Andrews-Cooper for this project.
  • Testing: The testing process was shared by our company’s resources and the client’s internal resources. Test plans and procedures were written, reviewed, and approved. Tests were assigned to team members to complete, and the overall test effort was managed by our lead engineers.
  • Design for Production/Manufacture: Andrews-Cooper worked with a 3rd party to create purchasing specifications and sourced the supplier for the molding.

Results:  Drawing on over 75 years of principle-level engineering experience in defibrillator development, Andrews-Cooper became a seamless extension of the customer’s engineering team on what would become a flagship product
