Anisotropic nanocomposite hydrogel

Номер: US0009206414B2
Автор: Wan-Kei Wan, Leonardo Millon, WAN WAN-KEI, MILLON LEONARDO
Принадлежит: AXCELON BIOPOLYMERS CORPORATION, WAN WAN-KEI, MILLON LEONARDO, AXCELON BIOPOLYMERS CORP

Anisotropic nanocomposite hydrogel materials are created using a process in which a hydrogel-forming material is crosslinked in the presence of nanoscale cellulose and subsequently thermally cycled under an applied tensile strain. Such materials are capable of exhibiting high mechanical and viscoelastic anisotropy, increased stiffness when subjected to large strain, and are suitable for a broad range of soft tissue replacement applications. In addition controlled release of bioactive agents properties can be designed into medical devices fabricated from such nanocomposite materials.

SURGICAL TRAINING AIDS AND METHODS OF FABRICATION THEREOF

Номер: US20120282584A1
Автор: Leonardo Millon, Wankei Wan, Mackenzie Quantz, MILLON LEONARDO, WAN WANKEI, QUANTZ MACKENZIE
Принадлежит: THE UNIVERSITY OF WESTERN ONTARIO

The present invention provides surgical training aids formed from hydrogels and adapted to exhibit realistic mechanical properties mimicking those of real organs. Surgical training aids are preferably fabricated by subjecting a concentration of polyvinyl alcohol to freeze-thaw cycles in a mold designed to approximate the shape of an organ, and process parameters are selected to tailor the mechanical properties of the formed hydrogel to those of the organ simulated by the surgical aid. The mechanical properties of the hydrogel forming the surgical training aid may be tailored by incorporating bacterial cellulose and by applying strain during hydrogel formation, thereby producing controlled anisotropy.

Номер: US20090214623A1
Автор: Hadi Mohammadi, Leonardo E. Millon, Wankei Wan
Принадлежит: Individual

The invention relates to an anisotropic hydrogel and a method of producing the anisotropic hydrogel. The hydrogel exhibiting anisotropic properties is poly(vinyl alcohol) produced by preparing a solution of poly(vinyl alcohol) with a pre-selected concentration, thermally cycling the solution by freezing and thawing, stretching the hydrogel and thermally cycling the hydrogel at least one more time The anisotropic hydrogel is used for tissue replacement and reconstruction, bioagent entrapment and delivery, in preparing ultrasound or radiofrequency thermal therapy transmission pads and substitutes for ice bags, as denture base, in soft contact lens material, for wound covering bandages and phantoms for medical-related use.
