description: 'Adona Medical is a clinical-stage medical device company headquartered
  in Los Gatos, California, and a Shifamed portfolio company, developing an adjustable
  interatrial shunt with integrated bi-atrial pressure monitoring for patients with
  advanced heart failure. The implant uses nitinol shape-memory geometry so the shunt
  flow channel can be enlarged or reduced after implantation, allowing hemodynamic
  therapy to be re-titrated as a patient''s condition evolves. The company completed
  enrollment in its ATHENS-HF first-in-human study of the device. Adona Medical is
  a device and clinical company rather than a software vendor: it publishes no public
  developer program, API, SDK, or machine-readable specifications, and its device is
  investigational and not approved for sale.'

  detail: >-
    Every path on adonamed.com — the homepage, /openapi.json, /llms.txt, all
    /.well-known/* discovery paths and a deliberately nonexistent control path alike —
    answers HTTP 202 with an `sg-captcha: challenge` header and a 169-byte SiteGround
    captcha redirect, so not one page or discovery document on the company's own host
    could be read; the api./developer./docs./status. subdomains are all NXDOMAIN and
    there is no GitHub organization, so no alternate reading path exists either.
