Chapter 2 of the PMBOK discusses stakeholders. Identifying stakeholders is a process that occurs throughout the entire project lifecycle and the project manager is expected to manage these stakeholders. In Medical Device Development what are some stakeholders and unique challenges to managing them in the industry?

For example, most projects in any industry have similar internal stakeholder. These include project sponsor, project manager, and project team members. In medical device development we also have the regulatory agencies and a unique set of customers. Customers or end users are often considered to be both the doctor and the patient and even the hospital. I have found that we spend a lot of time gathering feedback from doctors in medical device development, but very little time gathering input from patients.
