This is just a guess based on Google searches.

Exista un medic chirurg care se numeste Doru Georgescu in SUA.

He specializes in laparoscopic surgery, as well oncological surgery(colostomies, etc. ), and bariatric surgeries. He is also a consultant for Synthes Spine and Gore medical products. So, I imagine this should be a device and/or procedure named after him.

Nu am gasit referinta exacta. Probabil ca in engleza "inele" nu inseamna "rings" in contextul asta. Oricum, nu as folosi genitivul, ci as spune simplu "Georgescu rings" (they are not his, but were named after him...).
