Publication number: 20240117831Abstract: A post coupler having a top end portion and bottom end portion, a first body portion and a second body portion. Each body portion having an inner edge, an outer edge, a reverse flange, and a post stop. Each reverse flange forms a post receiving slot, and each post stop extends towards its respective body portion. The first and second body portions are coupled to each other at approximately 90 degrees. A method of using the post coupler comprises the steps of a) providing a first post section and a second post section, b) inserting the first post section along the post receiving slots until the first post section abuts one side of the post stops, and c) inserting the second post section along the post receiving slots until the second post section abuts an other side of the post stops.Type: ApplicationFiled: October 6, 2022Publication date: April 11, 2024Inventors: Christopher H.

Patent number: 7909867Abstract: The present invention provides materials that have high glucose and oxygen permeability, strength, water content, and resistance to protein adsorption. The materials include an interpenetrating polymer network (IPN) hydrogel that is coated with biomolecules. The IPN hydrogels include two interpenetrating polymer networks. The first polymer network is based on a hydrophilic telechelic macromonomer. The second polymer network is based on a hydrophilic monomer. The hydrophilic monomer is polymerized and cross-linked to form the second polymer network in the presence of the first polymer network. In a preferred embodiment, the hydrophilic telechelic macromonomer is PEG-diacrylate or PEG-dimethacrylate and the hydrophilic monomer is an acrylic-based monomer. Any biomolecules may be linked to the IPN hydrogels, but are preferably biomolecules that support the growth of cornea-derived cells. The material is designed to serve as a corneal prosthesis.Type: GrantFiled: December 13, 2006Date of Patent: March 22, 2011Assignee: The Board of Trustees of the Leland Stanford Junior UniversityInventors: David Myung, Christopher Ta, Curtis W.

Patent number: 7857849Abstract: A material that can be applied as implants designed to artificially replace or augment the cornea, such as an artificial cornea, corneal onlay, or corneal inlay (intrastromal lens) is provided. The artificial corneal implant has a double network hydrogel with a first network interpenetrated with a second network. The first network and the second network are based on biocompatible polymers. At least one of the network polymers is based on a hydrophilic polymer. The artificial cornea or implant has epithelialization promoting biomolecules that are covalently linked to the surface of the double network hydrogel using an azide-active-ester chemical linker. Corneal epithelial cells or cornea-derived cells are adhered to the biomolecules. The double network has a physiologic diffusion coefficient to allow passage of nutrients to the adhered cells.Type: GrantFiled: October 4, 2005Date of Patent: December 28, 2010Assignees: The Board of Trustees of the Leland Stanford Junior Iniversity, Santa Clara UniversityInventors: David Myung, Jaan Noolandi, Alan J.

The hydrophilic monomer is polymerized and cross-linked to form the second polymer network in the presence of the first polymer network. The telechelic macromonomer preferably has a molecular weight of between about 575 Da and about 20,000 Da. Mixtures of molecular weights may also be used. In a preferred embodiment, the hydrophilic telechelic macromonomer is PEG-diacrylate or PEG-dimethacrylate and the hydrophilic monomer is an acrylic-based monomer. The material is designed to serve as a contact lens.Type: GrantFiled: December 7, 2006Date of Patent: December 28, 2010Assignee: The Board of Trustees of the Leland Stanford Junior UniversityInventors: David Myung, Jaan Noolandl, Christopher Ta, Curtis W.

Publication number: 20070233240Abstract: The present invention provides a hydrogel-based intraocular lens (IOL) implant that can covalently attach to a lens capsule on implantation into an eye. The inventive IOL has a high refractive index, high elasticity, and is of a similar size to a naturally occurring lens. In addition, the IOL can be implanted in a smaller, dehydrated state, allowing the IOL to be placed in the lens capsule with a small incision (up to about 1/10 the volume of the IOL). Exposure to fluid can then initiate rapid swelling of the dried polymer to the shape and dimensions of a natural lens, with full occupation of the lens capsule. Upon equilibrium swelling, the IOL can then make contact with the inner aspect of the lens capsule and covalently bind to it. By this attachment process, the IOL may accommodate in a manner identical to that of the natural lens.Type: ApplicationFiled: March 16, 2007Publication date: October 4, 2007Inventors: Curtis Frank, Christopher Ta, David Myung, Jaan Noolandi, Michael Carrasco, Won-Gun Koh

Publication number: 20060287721Abstract: The present invention provides an artificial corneal implant having an optically clear central core and a porous, hydrophilic, biocompatible skirt peripheral to the central core. In one embodiment, the central core is made of an interpenetrating double network hydrogel and the skirt is made of poly(2-hydroxyethyl acrylate) (PHEA). In another embodiment, both the central core and the skirt are made of interpenetrating double network hydrogels. The artificial corneal implant may also have an interdiffusion zone in which the skirt component is interpenetrated with the core component, or vice versa. In a preferred embodiment, biomolecules are linked to the skirt, central core or both. These biomolecules may be any type of biomolecule, but are preferably biomolecules that support epithelial and/or fibroblast cell survival and growth. Preferably, the biomolecules are linked in a spatially selective manner. The present invention also provides a method of making an artificial corneal implant using photolithography.Type: ApplicationFiled: April 20, 2006Publication date: December 21, 2006Inventors: David Myung, Christopher Ta, Nabeel Farooqui, Curtis Frank, Won-Gun Koh, Jungmin Ko, Jaan Noolandi, Michael Carrasco

Patent number: 6976997Abstract: The invention provides implants suitable for use as an artificial cornea, and methods for making and using such implants. Artificial corneas having features of the invention may be two-phase artificial corneas, or may be three phase artificial corneas. These artificial corneas have a flexible, optically clear central core and a hydrophilic, porous skirt, both of which are biocompatible and allow for tissue integration. A three-phase artificial cornea will further have an interface region between the core and skirt. The artificial corneas have a high degree of ocular tolerance, and allow for tissue integration into the skirt and for epithelial cell growth over the surface of the prosthesis. The use of biocompatible material avoids the risk of disease transmission inherent with corneal transplants, and acts to minimize post-operative inflammation and so to reduce the chance or severity of tissue necrosis following implantation of the synthetic cornea onto a host eye.Type: GrantFiled: June 18, 2003Date of Patent: December 20, 2005Assignee: The Board of Trustees of the Leland Stanford Junior UniversityInventors: Jaan Noolandi, Christopher Ta, Philip Huie, Jr., Alan J.
