Patent number: 9534088Abstract: A polymeric material with a variable modulus of elasticity is described herein. The polymeric material described herein is useful for forming implantable medical devices (e.g. ophthalmic lenses, breast implants, and body augmentation devices). In addition, medical devices formed from the polymer material can be used to controllably release a therapeutic agent. Also, the polymeric material may be used to prepare topical compositions or other applications or devices where control of a mechanical property such as material modulus is important.Type: GrantFiled: March 6, 2013Date of Patent: January 3, 2017Assignee: Abbott Medical Optics Inc.Inventors: Can B Hu, Thuy Mai, Derek D Pham

Patent number: 9421091Abstract: An intraocular lens insertion apparatus includes a hollow tube having an interior wall defining a hollow space through which an intraocular lens may be passed from the open space into an eye. A lubricity enhancing component is covalently bonded to the hollow tube at the interior wall in an amount effective to facilitate the passage of the intraocular lens through the hollow space. The lubricity enhancing component includes a substituent component effective to reduce hydrolysis of said lubricity enhancing component relative to an identical lubricity enhancing component without the substituent component.Type: GrantFiled: February 16, 2015Date of Patent: August 23, 2016Assignee: Abbott Medical Optics Inc.Inventors: Harish Makker, Can B. Hu, Michael D. Lowery

Patent number: 9339373Abstract: A polymeric material with a molecular response time that makes it suitable for use near fragile body tissues. The polymeric material is useful for both low modulus and high modulus applications thereby simplifying the multi-part polymeric article manufacturing process and creating better integrated multi-part polymeric articles. Cross-linked polymers with different moduli may be obtained utilizing the same or similar starting materials but modifying the amount of catalyst, the amount of cross-linking agent, and/or the amount of methyl vinyl cyclics.Type: GrantFiled: March 28, 2012Date of Patent: May 17, 2016Assignee: Abbott Medical Optics Inc.Inventors: Can B. Hu, Michael D. Lowery

Patent number: 8323799Abstract: Soft, flexible highly lubricious coatings for polymeric IOL insertion cartridges that allow IOLs to be easily inserted through small bore cartridges suitable for use with small (less than 3 mm) incisions are provided. These lubricious coatings allow IOLs to be inserted into the eye of a patient without the risk of lens damage or transfer of lubricants to the lens surface during implantation. Specifically, polymeric coatings comprising a matrix polymer having an equivalent weight greater than 5000 g/eq are used to form interpenetrating networks (IPN) on the surface of hydrophobic structural polymers. The IPNs thus formed entrap highly lubricious hydrophilic compounds within the IPN using multi-functional cross linkers.Type: GrantFiled: October 26, 2011Date of Patent: December 4, 2012Assignee: Abbott Medical Optics Inc.Inventors: Can B Hu, Michael D Lowery, Harish Makker
