Publication number: 20130211516Abstract: Many modern implantable ophthalmic devices include electronic components, such as electro-active cells, that can leak harmful substances into the eye and/or surrounding tissue. In the implantable ophthalmic devices disclosed herein, electronic components are hermetically scaled within cavities formed by bonding together two or more glass wafers. Bonding the glass wafers together with laser fusion bonding, pressure bonding, or anodic bonding creates a seal that leaks at a rate of less than about 5×10?12 Pa m3 s?1 when subjected to a helium leak test. Hermetically sealed feedthroughs formed of conductive material running through channels in the wafers provide electrical connections to components inside the sealed cavities. In some cases, the conductive material has a coefficient of thermal expansion (CTE) that is roughly equal to (e.g., within 10% of) the CTE of the glass wafers to minimize leakage due to thermally induced expansion and contraction of the conductive material and the glass wafer.Type: ApplicationFiled: July 25, 2011Publication date: August 15, 2013Inventors: Ronald D. Blum, Amitava Gupta, Jean-Noel Fehr, Jean-Christophe Roulet, Urban Schnell, Walter Doll, Roland Michaely

Publication number: 20130211515Abstract: Astigmatism is an optical aberration that displaces the eye's vertical focal plane with respect to its horizontal focal plane. This displacement in focal planes, which may be caused by an irregularly shaped cornea and/or crystalline lens, causes images to appear blurry. Astigmatism can be corrected by implanting an optic, such as section of a spherical lens, whose projection onto a plane perpendicular to the optical axis is noncircular (e.g., rectangular or elliptical). Because the optic is noncircular, it provides more optical power along one axis than along another axis. As a result, it introduces an astigmatism that can be used to offset or compensate the eye's corneal and/or lenticular astigmatism when aligned properly with respect to the principal meridians of the cornea and/or crystalline lens.Type: ApplicationFiled: June 24, 2011Publication date: August 15, 2013Inventors: Ronald D.

Patent number: 8505833Abstract: A medical liquid transfer system includes a pump configured to transfer liquid between at least two containers. A detachable connector is detachably secured to the pump. The detachable connector has at least one pump passage to transmit pumping pressure from the pump to at least one of the containers. The detachable connector can include one or more liquid impermeable and gas permeable membranes to ensure the liquid is retained in the detachable connector. After the fluid is transferred the detachable connector is removed and replaced by a new one in order to prevent contamination of the pump. An interlock mechanism is used to prevent premature removal of the detachable connector and/or the container being filled.Type: GrantFiled: March 26, 2012Date of Patent: August 13, 2013Assignees: Roche Diagnostics Operations, Inc., Roche Diagnostics International AGInventors: Jean-Noël Fehr, Heiner Kaufmann, Rudolf Zihlmann, Sandro Niederhäuser, Christopher Wiegel, Eric Misselwitz, Christoph Rickert

Publication number: 20130102921Abstract: A contact lens shaped measuring device (1) includes sensor (3) having a protrusion (14) towards the cornea (22). The measuring device (1) is flexible to a degree that it is flattened by a closing eye lid and the protrusion creates an indentation of the cornea. The occurring force on the protrusion is measured by the sensor. Applying a constant lid acceleration/deceleration model to the movement of the lid and a mechanical model to the cornea, the tension of the cornea is determined and deduced from the force measured with the lid closed, yielding the true intraocular pressure. In an alternative, the protrusion is characterized by a discontinuity in its shape, or the sensor is subdivided, each subsensor being characterized by a protrusion of different shape. With the values obtained as extrema and at the discontinuity or with different protrusions, the cornea tension can be obtained by a (linear) extrapolation.Type: ApplicationFiled: October 20, 2011Publication date: April 25, 2013Inventors: Alain SAURER, Jean-Noel FEHR
