Hydrogel tissue expanders

The present invention provides tissue expanders comprising biodegradable, chemically cross-linked hydrogels which are elastic in the dry state. These biocompatible tissue expanders are self-inflating and membrane-free. They swell slowly and elicit minimal negative tissue responses, while allowing fo...

Zusammenfassung:	The present invention provides tissue expanders comprising biodegradable, chemically cross-linked hydrogels which are elastic in the dry state. These biocompatible tissue expanders are self-inflating and membrane-free. They swell slowly and elicit minimal negative tissue responses, while allowing for rapid and easy manipulation by the surgeon at the time of emplacement.
