  • Publication number: 20180325674
    Abstract: A surgical implant for a proximal carpal row replacement surgery employs a scanned image of each of the scaphoid, lunate and triquetrum bones for generating a unitary, homogeneous model defining a fused shape for implantation as the proximal carpal row. The implant utilizes a contralateral image of healthy bones of the patient for generating the replacement model, and employs shrink-wrap and smoothing processing to generate the unitary replacement. The resulting implant replaces the intercalary bone structures of the scaphoid, lunate and triquetrum with a single appliance, and is slideably engaged with the distal carpal row via a surgical tunnel and tethered by a resectioned tendon, ligament, or other connective member. The implant facilitates wrist function since the unitary implant replaces skeletal structures that are encapsulated by adjacent bones and frequently move as a unit, while eliminating gaps, voids and ligaments between the intercalary structure.

  • Publication number: 20180173010
    Abstract: A lens comprises an internal cavity structure formed by dissolution of a soluble insert material. The internal soluble material may dissolve through a body of a lens such as a contact lens in order to form the cavity within the contact lens. The cavity within the lens can be shaped in many ways, and corresponds to the shape of the dissolved material, such that many internal cavity shapes can be readily fabricated within the contact lens. The insert can be placed in a mold with a pre-polymer material, and the pre-polymer material cured with the insert placed in the mold to form the lens body. The polymerized polymer may comprise a low expansion polymer in order to inhibit expansion of the lens when hydrated. The polymer may comprise a hydrogel when hydrated. The soft contact lens material comprises a sufficient amount of cross-linking to provide structure to the lens and shape the cavity.

  • Publication number: 20180131847
    Abstract: Auxiliary units, in some instances implemented as a case for a wearable electronic device such as a wearable camera are described. The auxiliary units may include one or more electronic components typically included in the camera. By offloading an electronic component and the corresponding function (e.g., extended power capacity, memory capacity, wireless or other communication capabilities, etc.) to a removable auxiliary unit, the size of the wearable device can be advantageously further reduced.

  • Patent number: 9939659
    Abstract: A non-round fluid lens assembly includes a non-round rigid lens and a flexible membrane attached to the non-round rigid lens, such that a cavity is formed between the non-round rigid lens and the flexible membrane. A reservoir in fluid communication with the cavity allows a fluid to be transferred into and out of the cavity so as to change the optical power of the fluid lens assembly. In an embodiment, a front surface of the non-round rigid lens is aspheric. Additionally or alternatively, a thickness of the flexible membrane may be contoured so that it changes shape in a spheric manner when fluid is transferred between the cavity and the reservoir.
