    摘要: A method of monitoring cardiac dysfunction, such as pericardial effusion, is disclosed. The method uses an indwelling probe inserted within a coronary sinus or a chamber or vessel of the heart, the probe having motion sensing means configured to sense motion of the probe based on movement of the wall of the coronary sinus or other chamber or vessel. Data is obtained from the motion sensing means and processed to monitor for cardiac dysfunction. The monitoring can be in real-time and can utilise one or more three-axis accelerometers. In some embodiments, two or more three-axis accelerometers are spaced longitudinally along an elongate body of the probe, which can increase accuracy and reliability of monitoring.

    摘要: A microwave ablation device (10) comprises a feed line (22), a microwave radiator and a device outer sheath (46) in which at least part of the feed line (22) is contained. The sheath (46) in use, allows an irrigation liquid to flow therethrough, wherein the feed line has a junction (38) with the radiator (22) has an outer conducting shield (28) terminating and insulated at the junction (38). The feed line (22) has a conductive core (32) that extends to the radiator (24). The conductive core forms a radiating element (34) electrically insulated from its surrounding environment. The radiator (24) is unbalanced.

    摘要: The invention concerns a method for intra-operative monitoring of the effectiveness of transcatheter renal denervation in a patient, to assist in guiding the procedure and in particular for identifying a physiological procedural endpoint. Through aorticorenal ganglia pace-capture, renal sympathetic nerve function can be assessed. In accordance with the invention, sustained reduction or abolition of renal vasoconstriction induced by the pacing is used as an indicator of successful renal denervation.
