摘要:
The present invention includes a tissue scaffold suitable for use in repair and/or regeneration of musculoskeletal tissue when implanted in a body that includes a porous substrate made from a biodegradable, hydrophobic polymer having a modified hyaluronic acid complex dispersed on the surface of and/or, where the modified hyaluronic acid complex is insoluble in water, yet soluble in mixtures of organic and aqueous solvents in which the hydrophobic polymer is soluble.
摘要:
The present invention includes hyaluronic acid complexes of a monovalent alkali metal salt of hyaluronic acid and a tetra alkyl ammonium halide that are suitable for incorporation with tissue scaffolds that are suitable for use in repair and/or regeneration of muscoloskeletal tissue and that include a biodegradable, porous substrate made from a biodegradable, hydrophobic polymer, where the hyaluronic acid complex is substantially insoluble in water at room temperature, yet soluble in mixtures of organic and aqueous solvents in which the selected hydrophobic polymer is soluble.
摘要:
High refractive index copolymers with reduced glistenings are disclosed. The copolymers, which are particularly suitable for use as ophthalmic device materials, comprise a high molecular weight, reactive, linear polyethylene glycol component.
摘要:
Crosslinked lactam polymers are disclosed. Specifically, lactam polymers having pendant acrylate groups are crosslinked via a Michael addition type acrylate reactant. The crosslinked lactam polymers are useful in medical and pharmaceutical applications.
摘要:
This invention relates to wettable biomedical devices comprising amphiphilic block copolymers. The amphiphilic block copolymers are useful as internal wetting agents for biomedical applications, such as implantable devices, ophthalmic devices and in one embodiment, contact lenses.
摘要:
Disclosed are low-tack, hydrophobic, high refractive index, acrylic materials. These materials, especially useful as intraocular lens materials, contain one or more aryl acrylic hydrophobic monomers as principal device-forming monomers, a tack-reducing macromer additive and a glistening-reducing additive. In addition to their use as intraocular lens materials, the present materials are also suitable for use in other implantable ophthalmic devices.
摘要:
High refractive index copolymers with reduced tack are disclosed. The copolymers, which are particularly suitable for use as ophthalmic device materials, comprise a benzhydryl methacrylate or benzydryl methacrylate derivative monomer.
