Abstract: The present invention relates to a method and system for estimating blood pressure of a subject. In particular, but not exclusively, the method involves receiving a photoplethysmogram (PPG) signal from a light-based Pulse-Plethysmography sensor applied to the skin of a subject and reconstructing a pulse blood pressure waveform between systolic and diastolic blood pressure of the subject. Additionally, but not exclusively, the method involves processing the pulse blood pressure waveform and reconstructing an absolute blood pressure waveform of the subject.

Abstract: The present invention provides a method for the insertion of an artificial ligament into an ankle of a human. The method comprises drilling a first hole through the talar neck of the ankle, and drilling a second hole though the distal part of the fibular. The method further comprises passing the artificial ligament through the first hole, looping the artificial ligament over the dorsal part of the talus neck and using a soft loop of the artificial ligament to anchor the artificial ligament over the talar neck. The artificial ligament is then passed through the second hole and securing the artificial ligament onto the calcaneus using a screw inserted through a hard look of the artificial ligament.

Abstract: A scapula component (1) for a reverse shoulder prosthesis comprises a part spherical, convex, surface (3) which is less than a hemisphere. The part spherical surface does not have a rotational axis of symmetry, and may include a main circular surface portion and one or more subsidiary surface portions (5, 6, 7) depending from an edge of the main surface portion. A humerus component (200) for a reverse shoulder prosthesis comprises a cup member (202) having a part spherical, concave bearing surface (206) surrounded by an oval rim (208).
