Before you write: we are not BioDrain Medical, and we cannot help with a STREAMWAY unit. If you have a Streamway® system, or need parts, documentation or support for one, the product line has belonged to DeRoyal Industries, Inc. since March 2025 and DeRoyal is who to contact. If you are looking for the former company’s SEC filings, they are on EDGAR under CIK 0001446159. We cannot forward mail to any of those parties. What we are is an independent reference publication that happens to be published at this domain name; the whole story is on About.

Where to write

Two mailboxes, both live, both read by the same person — Zane Hitchcox, who publishes this site and writes all of it. There is no contact form, no telephone number, no chat widget and no ticket queue, and nothing you send is added to a mailing list, because there is no mailing list.

Either address reaches us; the split exists so that a correction is never lost in general mail. Nothing is answered by an automated system, and no reply you get from here was written by anyone but the publisher.

What we can answer

What we cannot answer

Corrections, and what we commit to

If we get something wrong, tell us and we will fix it in public. Corrections are dated, permanent, and describe the error rather than hiding it: the notice says what the page originally said and what it says now. We do not delete a wrong sentence and move on, and we do not quietly edit a page and let the old version disappear — silently rewritten pages are the failure this subject is built out of.

We aim to answer a correction within five working days and to publish a documented correction within seven, whether or not the person who found it wants credit. If we think you are wrong, you will get a reply saying so and setting out the document we are relying on, which is a better outcome for both of us than silence. Every correction appears at Corrections, newest first and never removed, and permanently at the top of the page it corrects. The full policy is at Editorial standards.

What happens to what you send

Mail is read by one person and is not shared, sold, published or added to any list. We do not publish your name, your employer or your message without asking you first, and a correction is credited only if you want it to be — plenty of people who work in an operating room have good reasons not to be named next to a criticism of a policy. This site sets no cookies, runs no analytics and makes no third-party request; what the server logs is set out at Privacy.

If you followed an old link to this address

You have probably arrived from a press release published between 2009 and 2013, which linked to the contact page of the company that then used this domain name. That company’s website is gone, none of it is republished here, and this page is not its replacement. What became of the company, of its product line and of this domain name is set out with dates and primary sources in the Domain Record. If you believe an address on this domain ought to resolve to something and does not, write to the editor and we will say so in public either way.
