I use this website for work. That search page is certainly dated, but may I suggest there is actually the very similar Devices@FDA: https://www.accessdata.fda.gov/SCRIPTS/cdrh/devicesatfda/ind...

The Devices@FDA is a single search box, while the one the author used breaks out by field, more useful if you know exactly what company name, etc. you're looking for. Also, Devices@FDA searches both 510(k) and PMA's (the other 1%).

As a side note, for a while the Devices@FDA page was not linked from the "databases" root https://www.fda.gov/medical-devices/device-advice-comprehens.... I emailed them at the comments and feedback link, and they added it within days!
