A provisional establishes a priority date while the invention is refined. It does not become a patent on its own and is never examined or published.

The ISR for PCT/US23/60184 identified 23 references across US, Canadian, and European prior art — none of which combined radial expansion with the single-operator, single-use design claimed in this application.

Publication gives provisional protection — others are on notice that a patent application is pending. The published application is freely viewable through USPTO Patent Public Search.
