Abstract: A device for cardiac valve repair, the device comprising: a stent adapted to anchor to at least one tissue site, the tissue site located upstream with respect to a heart valve of a patient; and a neo-leaflet arranged to extend from the upstream anchoring means, the neo-leaflet comprising a free end, wherein the neo-leaflet is operable to extend across the heart valve via a commissure in between two heart valve leaflets of the patient's heart and locate the free end downstream from the heart valve and the neo-leaflet operable to coapt with the heart valve leaflets of the patient's heart to prevent and/or minimize a backflow of blood. The present invention is suitable for the treatment of heart valves using minimally invasive approaches. Additionally, the present invention is directed to a method of implanting a device for cardiac valve repair in a patient's heart.

Abstract: A method of modifying a retina fundus image for a deep learning model is disclosed. In a described embodiment, the method includes converting a retina fundus image to a binary image by converting pixels of the retina fundus image to low intensity modified pixels and high intensity modified pixels of the binary image, and determining a first boundary between the low intensity modified pixels and high intensity modified pixels of the binary image. The method further includes removing outlier boundary values from the first boundary, constructing a second boundary from remaining boundary values, identifying the pixels of the retina fundus image that are within the second boundary, and constructing a modified retina fundus image containing the identified pixels for a deep learning model.

Abstract: A method for the prognosis of response to treatment for a patient suffering from cancer, the method comprising: measuring the expression of at least one immune marker in a leukocyte sample taken from the patient with cancer; classifying the patient sample into (i) sustainable responders (SR) to selective internal radiation therapy (SIRT) or (ii) transient/non-responders (TR/NR) to (SIRT) based on expression of the at least one immune marker in relation to a predetermined value and treating sustainable responders (SR) to SIRT or SIRT or a composition comprising SIRT and an immunotherapy. In a preferred embodiment, the method is for the prognosis of response to treatment of a Hepatocellular carcinoma (HCC) patient comprising detecting the co-expression of PD-1 or Tim-3 with CCR5; or expression of PD-1, Tim-3, CXCR6, or combinations thereof in a leukocyte sample taken from the patient.

Abstract: There is provided a device for insertion into a body cavity, the device includes an insertion member configured to be inserted into the body cavity, an expandable member coupled to the insertion member, the expandable member capable of being expanded to apply pressure onto tissue within the body cavity, a first member configured for storing a first endothermic reactant therein, and a second member configured for storing a second endothermic reactant therein. In particular, the first and second members are configured to, in a state of the device (e.g., compressed state), allow the first and second endothermic reactants to cooperate to effect an endothermic reaction to generate an endothermic product. Furthermore, the expandable member is configured to receive at least one of the first or second endothermic reactant and the endothermic product through a channel within the insertion member. There is also provided a method of fabricating a device for inserting into a body cavity.

Abstract: A device and method for measuring respiratory air flow of a subject are provided. The device includes a hollow member having a proximal end, a distal end and a flow passage formed between the proximal and distal ends. The proximal end is configured to be received in a mouth of a subject. A flow sensor, such as thermal mass flow sensor, is disposed in the flow passage and configured to sense characteristics of an air flow in the flow passage. A processor is communicatively coupled to the flow sensor and configured to determine, based on an output from the flow sensor, whether the sensed characteristics of the air flow correspond to predetermined parameters.
