Sure. Understandable. Another suggestion: UpToDate has an article on “Surgical treatment of erectile dysfunction, including implantation of penile prostheses and penile vascular (arterial and venous) reconstruction,” at https://www.uptodate.com/contents/surgical-treatment-of-erectile-dysfunction . Check out the outline to see if it might have useful information. UpToDate is a point-of-care clinical resource with more than 10,000 topics and patient information and a patient/caregiver 7-day subscription is $20.

During research did you see the Wikipedia piece: (https://en.wikipedia.org/wiki/Penile_implant piece ) listing manufacturers? (Note that Wikipedia flagged it for possibly failing to comply with their neutral point of view policy.)
