Abstract: A membrane actuator device includes a housing with an entrance port and an exit port connected by a fluid flow passageway. A gas generation chamber is disposed within the housing, the gas generation chamber comprising a first opening and a gas generating element. A membrane actuation chamber has a second opening and may be defined at least in part by a flexible membrane configured to deflect and affect fluid flow through the fluid flow passageway. A barrier spans the width of the first opening of the gas generation chamber and is disposed in a manner that reduces the likelihood that gas molecules will pass from the gas generation chamber to the membrane actuation chamber.

Abstract: Vascular endothelial growth factor A (VEGFA) is a chemical signal produced by cells that stimulates the growth of new blood vessels, and overexpression of VEGFA can lead to undesirable physiological conditions. Through the identification of new siRNA and modifications that improve the silencing ability of these siRNA in vivo, therapeutic compositions and methods have been invented to address the problems associated with this overexpression.

Abstract: The invention provides functionalized polypeptides, especially therapeutic polypeptides (e.g., scFv), comprising a linker sequence that can be rapidly and specifically functionalized by the addition of one or functional moieties (e.g., PEG) or binding specificities (e.g., an amino acid sequence with a particular binding specificity). Such functionalized polypeptides are advantageous in that they have improved pharmacokinetic properties (e.g., improved in vivo half-life, tissue penetration and tissue residency time) over non-functionalized polypeptides. Methods for the rapid and reproducible generation of functionalized polypeptides are also provided.

Abstract: In various embodiments, aspiration tubing connecting a handpiece to a surgical console may include a high compliant section, a transition section, and a low compliant section. In some embodiments, the high compliant section may have a lower durometer and/or different geometry than the low compliant section. The transition section may take a number of forms, including a connector or a continuous section of tubing that gradually increases in durometer and/or changes geometry through the length of the tubing. In the various embodiments, the high compliant section may provide flexibility near the handpiece to make the handpiece easier to hold and maneuver while the low compliant section may reduce the effects of occlusion break surge. In some embodiments, the high compliant section may include, for example, ribs, stiffening rings, a stiffening sleeve, or a stiffening sock to increase the stiffness of the high compliant section.

Abstract: In various embodiments, an ophthalmic injection device may include a dispensing chamber, a first thermal sensor coupled to the dispensing chamber, a temperature control layer coupled to the dispensing chamber, a second thermal sensor coupled to the dispensing chamber, and a first processing device. The first processing device may be configured to receive temperature information from the first thermal sensor and the second thermal sensor and control the temperature control layer using the received temperature information. In some embodiments, the first processing device may receive temperature information directly from the second thermal sensor (e.g., in analog form) and may compare the temperature information from the first thermal sensor (e.g., received from the second processing device in digital form) and the second thermal sensor to detect temperature offsets between the two sensors.

Abstract: The invention provides interfering RNA molecule-ligand conjugates useful as a delivery system for delivering interfering RNA molecules to a cell in vitro or in vivo. The conjugates comprise a ligand that can bind to a low density lipoprotein receptor (LDLR) or LDLR family member. Therapeutic uses for the conjugates are also provided.
Abstract: In various embodiments, a phacoemulsification cutting tip with a straight shaft and an angled portion off of the straight shaft may include a hook on the angled portion to move an axis of rotation of the cutting tip closer to alignment with an extended centerline of the shaft. The cutting tip may be configured to torsionally rotate back and forth on an axis perpendicular to a centerline of the shaft (e.g., rotation around a y-axis). In some embodiments, lateral vibrations (e.g., side to side along an x-axis or z-axis perpendicular to the y-axis) that result from torsional rotation around the y-axis in a cutting tip without the hook may be reduced through use of the hook to balance the otherwise eccentrically weighted hook.

Abstract: A method of testing visual performance includes determining a difficulty rating for each of a plurality of visual recognition tests. The method further includes displaying one of the visual recognition tests to a subject and receiving from the subject a response to the visual recognition test. After receiving the response to the visual recognition test, a subsequent visual recognition test is selected to have a difficulty rating determined based on the response received from the subject, the subsequent visual recognition test is displayed, and a response is received from the subject. The subsequent visual recognition tests are repeated until a predetermined number of responses is reached. A visual performance score is determined based on the set of responses received from the subject and the difficulty ratings for the visual recognition tests displayed to the subject is then output.
