BiVACOR

BiVACOR, Inc. is a privately held, clinical-stage medical device company with corporate operations in Huntington Beach, California, clinical operations in Houston, Texas, and engineering operations on the Gold Coast, Queensland, Australia. It develops the BiVACOR Total Artificial Heart (TAH), a titanium biventricular rotary blood pump built around a single magnetically levitated rotor with a dual-sided impeller that replaces both ventricles of a failing heart, with no valves, flexing diaphragms or mechanical bearings, and flows above 12 L/min. Founded by Chief Technical Officer Daniel Timms, PhD, and led by CEO Jim Dillon with Chief Medical Officer William E. Cohn, MD, the company completed the first-in-human implantation at The Texas Heart Institute in July 2024 under an FDA Early Feasibility Study, received FDA Breakthrough Device Designation in May 2025, and was accepted into the FDA Total Product Life Cycle Advisory Program in August 2025. The TAH is an investigational device, limited by federal law to investigational use, and is not approved for commercial sale. BiVACOR is a medical hardware and clinical-research business - it publishes no developer program, public API, SDK, or machine-readable API contract.

BiVACOR is profiled on the APIs.io network. Tagged areas include Company, Medical Devices, Healthcare, Cardiology, and Heart Failure.

Regulatory Posture applies to this provider. Its tags matched the Health regime, so Regulatory Posture carries 15 points of the composite. If this regime is wrong for your business, say so on your provider repo — the applicability map is public and we will correct it.

Create-or-Update Ergonomics could not be measured. We hold no machine-readable contract for this provider to read, so there is nothing to measure a write surface against. Excluded rather than scored zero: never-measured and measured-empty are different facts. Publishing an OpenAPI is what makes this facet — and several others — scorable at all.

The six quality facets above are damped to 85 points between them, because the conditional facet above carries the other 15. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 85% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.

Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/bivacor: open an issue to ask a question, or submit a pull request to add artifacts.

  detail: BiVACOR is a clinical-stage medical device manufacturer whose product is an implantable titanium total artificial
    heart, not software; bivacor.com is a single-page WordPress marketing site whose 15-URL sitemap contains no developer,
    API or documentation path, and api./developer./docs./portal./status.bivacor.com have no DNS record at all - the only 200
    on any contract-discovery path is /wp-json/, the stock WordPress REST API that ships enabled by default and is not a product
    API.
