  • Publication number: 20190302022
    Abstract: Disclosed is a localised surface plasmon resonance (LSPR) nanopillar assembly. The LSPR assembly is for use in sensing the presence of a biomarker when attached to a quantum dot. The LSPR assembly comprises a substrate and an array. The array comprises a LSPR nanopillar and a polymer spacer attached to the nanopillar. The LSPR assembly further comprises an antibody attached to the at least one polymer spacer. In the LSPR assembly, a combined height of the polymer spacer and antibody is selected by varying the number of monomer units of the polymer spacer, so that, when in use with the biomarker and the quantum dot, the quantum dot is at a predetermined distance from the nanopillar.

  • Patent number: 10076331
    Abstract: A device and method for forming an anastomotic joint between two parts of a human or animal body having a hollow connector with at least two proximal arms biased towards an open position; and at least two distal arms biased towards an open position, wherein in use when pressure is applied to the proximal arms to overcome the bias into a position in which the proximal arms are closer to each other; similarly pressure is applied to the distal arms to overcome the bias into a position in which the distal arms are closer to each other; the distal end can be pushed into a passage in the first human or animal body part until the distal arms are located in the first lumen of the first body part and released allowing the distal arms to move to the biased position to urge against the first lumen of the first body part; and the proximal end can be pushed into a passage in the second human or animal body part until the proximal arms are located in the second lumen of the second body part and released allowing the proxim

  • Patent number: 8687866
    Abstract: An optical coherence tomography (OCT) image of the anterior chamber of an eye is processed to determine automatically a location in the image corresponding to Schwalbe's line. First, the method finds the location of the corneal endothelium. Then the method fits a model to the detected corneal endothelium. Then the method determines the location of Schwalbe's line based on the relationship between the detected corneal endothelium and the fitted model, such as where the detected corneal endothelium diverges most from the fitted model. The Schwalbe's line is used to obtain a numerical measure of the anterior chamber angle of the eye. The method can be used in a process for screening patients for glaucoma. In the case of patients found to be suffering from glaucoma, treatment can be performed.

  • Patent number: 6538634
    Abstract: An apparatus for use in simulated image guided surgery comprises a positional transducer, clamping means located proximate to the transducer, and a processor. The transducer is responsive to a thin flexible member that can be manipulated by a user, and produces signals representative of displacement and rotation of the thin flexible member. The clamping means responds to a controlling signal to apply a predetermined variable clamping force to the flexible member. The processor receives these displacement and rotation signals, and is programmed to plot the path of the flexible member therefrom as it is manipulated by the user. Additionally, the processor produces the controlling signal to the clamping means in response to the instantaneous position along the path. The processor may be coupled to a display device for displaying an image of the instantaneous position of the flexible wire therealong, or other information. The invention also includes a related method for the simulation of image guided surgery.
