High School Summer Program

I am becoming a junior soon and I plan to major in neurosurgery. For the coming summer, I want to become involved in prestigious summer programs that would look good on my college application as well as give me a insight on what it is like to work in the medical field.

Can someone recommend a good high school summer program or internship that would give a good experience? The program/internship can be anything related to the medical field or even biomedical engineering. The program/internship should be preferably in New York City, but anywhere in New York is fine.
