  • Publication number: 20190151337
    Abstract: This invention is based on the discovery that many eye conditions associated with aging are mediated at least in part by cells bearing a senescent phenotype. Senescent cells accumulate with age, and express factors that contribute to the pathophysiology of age related conditions. The data show that in age-matched patients, the severity of age-related conditions correlates with the abundance of senescent cells, and that clearing senescent cells can help abrogate the condition. Small molecule drugs that remove senescent cells from affected tissue in the eye are provided that have special efficacy in treating ophthalmic conditions. They not only inhibit progression of the disease, they can also reverse some of the pathophysiology—such as neovascularization and vaso-obliteration—that lead to vision loss. These senolytic agents have an appropriate dose and specificity profile to be effective in the clinical management of previously intractable ophthalmic conditions.

  • Publication number: 20180083668
    Abstract: Described herein are methods of making and using and apparatus for wirelessly communicating data and providing power, particularly from a location exterior to a body and to an implantable device disposed within a body with tissue. The described embodiments provide apparatus and methods for efficiently transfer data and power between an external transceiver and an (implanted) biomedical device. The method is to modulate power carrier, which wirelessly powers the device, using an asynchronous modulation scheme, such as amplitude shift keying (ASK) modulation, with minimal modulation depth in order to not disrupt the power flow. The digital data is encoded in the pulse width, eliminating the need for synchronization to the power carrier signal and further minimizing the power consumption necessary for data transfer. Additionally, a reverse backscatter method for obtaining data from the implant is described that has flexible, low power operation.

  • Publication number: 20170250577
    Abstract: A planar immersion lens can include any number of features. A planar immersion lens can be configured to control a phase profile of an incident wave by modulating the incident wave with sub-wavelength structures of varying impedances. The planar immersion lens can also be directly excited, with electronics or other subwavelength sources coupled to the planar immersion lens, to generate a wave with the desired phase profile. The planar immersion lens can include a plurality of metallic elements and passive elements disposed over a substrate. The passive elements can be selected, based on both the intrinsic and mutual impedances of the elements, to shape the spatial phase profile of the incident wave within this phase range. The phase gradient can be introduced along the incident material/refractive material interface to focus the incident wave into the refractive material having wave components at or beyond the critical angle. Methods are also provided.
