I think project managers are like a lot of different professions in that you are very specialized in certain types of projects. There are some universal principles such as the initiate, plan, execute, monitor/control, and close phase cycle. These are the basic ways to complete any type of project and generally be successful if you utilize them. There are also responsibilities such as risk management which needs to be done throughout the project. All industries from construction to software need to account for risk. The medical device industry though, is an industry which is extremely regulated (by the FDA) and requires certain deliverables and standards of quality that project managers need to account for and integrate into the project breakdown. This will also push back many milestones since the FDA takes a long time to give responses to certain submissions. But not abiding by these standards will delay the project or even put it in risk of failing all together. The medical device industry is unique in terms of dealing with the FDA.
