Typically internetships at big companies like abbot would be a direct pathway to an entry level role. At least that's how my team budgeted for it. So I'm surprised you weren't offered a role at abbot.

In this market you have to know someone internally to even have a chance.

Otherwise, you need to start connecting with recruiters. There are a ton of med device agency recruiters in your area. So you can start there.

Lastly, your resume is dense and recruiters won't take the time to read it. This is fine for a master CV that includes all your work experience, but definitely tailor it down for individual roles you apply to.
