    Abstract: A surgical stapler includes a proximal end and a distal end and an anvil at the distal end for providing resistance to staples during the stapling operation of the surgical stapler. The anvil may include a number of segments arranged end-to-end. The anvil is elongated in the collapsed state, the anvil being elongated generally in a first direction D1. The anvil is configured such that the segments rotate about a rotation axis along a perpendicular second direction D2 when the anvil is actuated between the deployed and the collapsed states. The anvil is configured such that adjacent segments pivot relative to each other about a pivot axis along a third direction D3 when the anvil is actuated between the deployed and collapsed states. The stapler also includes an actuator mechanism, wherein the actuator mechanism is configured to be controlled from a location on the surgical stapler towards the proximal end.

    Abstract: A surgical retractor tool for removing an object from the stomach or from the oesophagus. The tool includes a flexible steerable tube for insertion into the body via the oral cavity and a gripper at the distal end of the tube for gripping an object in the stomach or the oesophagus in order to allow for removal of the object from the stomach or the oesophagus. The gripper includes first and second rotatable gripper surfaces and a clamping mechanism for moving the gripper surfaces to clamp the object. The rotatable gripper surfaces are arranged to rotate relative to the tube in order to allow a longitudinal axis of a gripped object to move into alignment with a longitudinal axis of the tube.

    Abstract: A method for processing echocardiography data to enable automatic functional measurements based on cardiac ultrasound images as an input, including (i) classification of the cardiac ultrasound images to ensure that relevant images are passed on to the next steps, optionally utilising a first neural network, such as a convolutional neural network, (ii) segmentation and semantic partitioning of the left ventricle (LV) myocardium to extract relevant parts of the image, optionally by using a second neural network, (iii) regional motion estimates to determine a mapping of displacements in the extracted parts of the image and to output estimated tissue motion vectors for the extracted parts of the image, optionally using a third neural network, and (iv) fusion of measurements via state estimation applied to the tissue motion vectors and thereby incorporating a temporal domain to produce data showing variation of the estimated measurements over time.

    Abstract: An ultrasound imaging method in which ultrasound signals are transmitted into a living organism, reflected from fluid flowing along a path within the organism, and received by an ultrasound transceiver system with a resolution limit in a first direction. These signals are used to generate data representing a sequence of images over time; each image including a speckle pattern arising from interference within the reflected ultrasound signals. A peak-sharpening operation is applied to the image data, generating data representing a sequence of resolution-enhanced images, each having a resolution in the first direction finer than the resolution limit of the transceiver system in that direction, and including a respective peak-sharpened speckle pattern. A combining operation is applied to generate data representing an output image in which the path of the fluid is represented by a superimposition of the peak-sharpened speckle patterns from the resolution-enhanced images.
