    摘要: An arthroplasty device is provided having an interpenetrating polymer network (IPN) hydrogel that is strain-hardened by swelling and adapted to be held in place in a joint by conforming to a bone geometry. The strain-hardened IPN hydrogel is based on two different networks: (1) a non-silicone network of preformed hydrophilic non-ionic telechelic macromonomers chemically cross-linked by polymerization of its end-groups, and (2) a non-silicone network of ionizable monomers. The second network was polymerized and chemically cross-linked in the presence of the first network and has formed physical cross-links with the first network. Within the IPN, the degree of chemical cross-linking in the second network is less than in the first network. An aqueous salt solution (neutral pH) is used to ionize and swell the second network. The swelling of the second network is constrained by the first network resulting in an increase in effective physical cross-links within the IPN.

    摘要: Surface modification methods for an interpenetrating polymer network (IPN) hydrogel to provide a basis for cell or tissue attachment are provided. The method involves the activation of functional groups on the surface of the IPN hydrogel. The activated functional groups are then reacted with amine-containing molecules or hydroxyl-containing molecules. The methods (i) can be performed in an aqueous environment and do not require the use of any organic solvent, (ii) do not require UV treatment, thereby avoiding denaturation of the IPN hydrogel or proteins, and/or (iii) can be performed as a one pot reaction.

    摘要: Three-dimensionally (3-D) shaped interpenetrating double network (IPN) hydrogel based on a first network and a second network are provided. The 3-D shape is characterized by a non-uniform distribution of the second network (e.g. carboxylic acid groups) when in hydrated state. The 3-D shape can further be characterized by changes in the radius of curvature of the shape. The 3-D IPN hydrogel is created by applying a non-uniform illumination pattern to polymerize the second network of monomers within a layer of a first network. In hydrated state, the second network causes a swelling force that is resisted by the first network. The non-uniformal distribution of the second network with the first network is responsible for the 3-D of the resulting IPN. The invention can find use in ophthalmic applications as well as non-ophthalmic applications.
