getting a research coop as a bme major?

How do people get research coops in a profs lab? I am interested in doing a research coop next year summer and I was wondering what I need to do in order to secure one. I have a 2.3 gpa, apart of a design team but I have no research experience. Should I try volunteering in a lab this summer or focus on other things?

also can you get a research based coop in a profs lab that is different from your uni?
