Method and apparatus are disclosed for removing biopolymer constructs (12) from support structures (13) used to impart a selected shape to the biopolymer. The biopolymer construct (12) and the support structure (13) are in intimate contact at an interface (32) and adhere to each other. The support structure includes an endcap (14) adapted for introducing a fluid to the interface (32) for reducing adhesion between the biopolymer structure and the support structure by applying a separating force at the interface (32) thereby facilitating removal between the support structure (13) and the biopolymer construct (12).

Why it's free to use
- Filed May 6, 1998. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended May 6, 2018.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by May 6, 2020.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
