Don & List:
For the last 17 years, we have been involved in concerted efforts to
reproduce various anatomical organs and structures. These models are
primarily used for medical training procedures as well as research
efforts. We have developed several proprietary techniques that allow us
to consistantly produce realistic anatomical structures.
Most of our products require and are composed of consistent layer(s)
applied to actual biological castings. In models for use with
endoscopic procedures, cellular structure are often present. We
currently have several products that are available through licensed
distributors, as well as direct sales. We invite you to review our web
page (http://www.pdsiusa.com/alm) on the hollow Adult Lung Model
(ALM-II). If any of you have specific product requirements in this
area, we invite you to contact us.
Kindest Regards,
Craig
