Where can I find tech specs for prosthetic heart valves

Click For Summary
Technical specifications for prosthetic heart valves, specifically the bi-leaflet valve and the Starr-Edwards valve, are sought for a CFD analysis project. Patent US4935030 is suggested as a starting point for the bi-leaflet valve. There is uncertainty regarding the current patent status of the Starr-Edwards valve, as it may have expired. The discussion indicates that further patent searches could yield additional information. Overall, patents are recommended as a primary source for the needed technical details.

So I am doing a project for an advanced fluids class where I plan to do a CFD analysis of two different prosthetic heart valves, the bi-leaflet valve and the ball and cage (star-edwards). I cannot seem to find the technical specifications or drawings that I need in order to make a good cad model. Does anybody know where I might find such info? Thanks

Perhaps the Patent US4935030, for the bi-leaflet valve would get you started?

I wonder if the Starr-Edwards may have expired, it is mentioned in some more recent patents but I couldn't find it in a quick search.

Thanks! That helps a lot.
 

Thread 'UV filter for home central heating?'

Had my central air system checked when it sortta wasn't working. I guess I hadn't replaced the filter. Guy suggested I might want to get a UV filter accessory. He said it would "kill bugs and particulates". I know UV can kill the former, not sure how he thinks it's gonna murder the latter. Now I'm finding out there's more than one type of UV filter: one for the air flow and one for the coil. He was suggesting we might get one for the air flow, but now we'll have to change the bulb...
