20090039535 | Extended Wear Ophthalmic Lens - A method for making a silicone hydrogel contact lens is provided. In one embodiment, a prepolymer mixture is polymerized in a lens mold in an atmosphere having less than about ppm oxygen to form a silicone hydrogel contact lens suitable for extended wear as characterized by producing less than 10% corneal swelling after a period of continuous wear of 7 days including normal sleep periods. In one embodiment, the prepolymer mixture comprises at least one oxyperm material containing hydrophilic groups, wherein the at least one oxyperm material is a siloxane-containing macromer or monomer, at least one ionperm material, and a cross-linking agent. In certain embodiments, the polymerization of the prepolymer mixture may be carried out in an atmosphere having less than about 1000 ppm oxygen. | 02-12-2009 |
20090046242 | Extended Wear Ophthalmic Lens - An ophthalmic lens suited for extended-wear periods of at least one day on the eye without a clinically significant amount of corneal swelling and without substantial wearer discomfort. In one embodiment, an opthalmic lens is a copolymerization product of at least one oxyperm, at least one ionoperm, and a crosslinker. In one embodiment, a lens has a tensile modulus of less than about 3.0 MPa, yet in another embodiment, the tensile modulus is between about 0.5 to about 1.5 MPa. | 02-19-2009 |
20090118455 | SILOXANE-CONTAINING POLYURETHANE-UREA COMPOSITIONS - An improved biostable polyurethane-urea elastomeric composition derived from a silicon-containing diamine of formula (I). | 05-07-2009 |
20100238398 | Extended Wear Ophthalmic Lens - An ophthalmic lens suited for extended-wear periods of at least one day on the eye without a clinically significant amount of corneal swelling and without substantial wearer discomfort. In one embodiment, an opthalmic lens is a copolymerization product of at least one oxyperm, at least one ionoperm, and a crosslinker. In one embodiment, a lens has a tensile modulus of less than about 3.0 MPa, yet in another embodiment, the tensile modulus is between about 0.5 to about 1.5 MPa. | 09-23-2010 |

20120149965 | Radiation Therapy Delivery System and Radiation Therapy Treatment Planning - The invention relates to a radiation therapy delivery system for use in effecting radiation therapy of a pre-selected anatomical portion of an animal body in which the delivery means displaces said at least one energy emitting source along a path through at least part of one of at least one catheter in a continuous motion using a pre-determined velocity profile along said paths, said velocity profile determined by solving an optimization problem in three-dimensions defined for a function describing the spatial dose distribution. The invention relates also to a radiation therapy treatment planning system and a method for generating a radiation treatment plan for use in effecting radiation therapy of an anatomical portion of an animal body in which the movement of the radiation source through the anatomical portion is continuous. | 06-14-2012 |
