Abstract: Systems and methods for mitral valve repair having a docking station and a valve implant. The docking station is an anchoring device having a helix structure. The valve implant is made of an expandable frame and a valve, and is radially expandable to a diameter that is at least the same as an expanded diameter of the anchoring device. The method of delivering the docking station and valve implant is performed by inserting the components through device delivery catheters.

Abstract: Methods and apparatus are provided for repairing or replacing a defective cardiac valve including an anchor having a double helix configured to engage the cardiac valve leaflets of a diseased or defective cardiac valve, and a replacement valve body disposed in an expandable stent configured to be disposed within the anchor so that the anchor limits expansion of the expandable stent. The expandable stent of the replacement valve body may be self-expanding or mechanically expanded, e.g., using a balloon catheter or catheter-based mandrel and the valve body may be formed of animal tissue or a synthetic fabric.

Abstract: A device operable to calculate a physiological parameter characteristic of a health condition of a human subject includes a finger cuff that is wearable on the subject's finger and operable to measure the patient's peripheral blood pressure waveform. A memory unit stores the measured peripheral blood pressure waveform, and an adjustable pressure transfer function, which includes at least one adjustable characteristic. The patient's cardiac output is estimated based on the stored measured peripheral blood pressure waveform, and the pressure transfer function is then adjusted based on that estimated cardiac output. The subject's aortic blood pressure waveform is then reconstructed from the stored peripheral blood pressure waveform and the adjusted pressure transfer function. A computing unit then calculates the physiological parameter from the reconstructed aortic blood pressure waveform.

Abstract: A method of determining the oxygen delivery, comprising the steps of non-invasive measurement of the arterial blood pressure waveform, determination of cardiac output from a pulse wave analysis of said blood pressure waveform, non-invasive measurement of oxygen saturation and hemoglobin concentration and real time calculation of oxygen delivery based on the measured quantities.

Abstract: The invention relates to a method 10 for determining a beat-to-beat stroke volume 9a and/or a cardiac output 9b based on a measurement 2 of suitable arterial pressure data. At the step 4 a waveform of the arterial pressure pulse is assessed based on data obtained during the measurement of step 2. At step 6 a compliance or impedance in dependence of at least one measurement of arterial pressure data is computed using a non-linear model 7. The non-linear model may comprise an arctangent model. The arctangent model may be differentiated numerically or analytically to obtain the compliance or the impedance of an aortic portions. The thus obtained compliance or impedance may then be substituted into a linear model 8. The linear model 8 may comprise a Windkessel model 8a, or a Waterhammer model 8b or any other suitable linear pulse contour model 8c. As a result, the beat-to-beat stroke volume 9a and/or cardiac output 9b are computed.
