Abstract
In order to bestow on implantation devices, such as vascular prostheses, a certain degree of mechanical consistency and/or properties of tightness, operating in a non-traumatic way, there is envisaged the use of an element with modifiable structure. This is an element comprising a hydrophilic body that is able to absorb a mass of liquid so as to assume, as a result of the absorption of said mass of liquid, a certain degree of mechanical consistency. Preferably, the aforesaid element with modifiable structure has a base of mixtures of polymers such as polyvinyl alcohol and gellan, so as to give rise to hydrogels or else films that, in turn, give rise to hydrogels by hydration.
