A method of hydrating a sponge material for delivery to a body. The method includes the steps of placing a dry piece of sponge in a container at a first pressure. A hydrating fluid is then introduced into the container to hydrate the sponge. The pressure within the container is changed between the first pressure and a second pressure. At least a portion of the hydrating fluid is removed from the sponge, and the sponge is delivered to a bodily site.

The system of claim 14, wherein said atrial pressure sensor comprises an apex cardiograph in communication with an atrial-pressure acquisition-unit. 16. The system of claim 13 wherein said second amplitude sensor comprises an arterial pressure sensor. 17. The system of claim 13 wherein said event detector is selected from the group consisting of an electrocardiograph and a phonocardiograph. 18. A method of non-invasively obtaining a left-ventricular pressure waveform, said method comprising: selecting, from a first signal, a first signal portion that corresponds to a first phase of a cardiac cycle; selecting, from a second signal, a second signal portion that corresponds to a second phase of said cardiac cycle; determining a temporal relationship between said first and second signal portions; and time-shifting said first and second signal portions consistent with said temporal relationship. 19. A system for non-invasively generating a ventricular pressure waveform, said system comprising: a non-invasive barograph for obtaining first data and second data indicative of first and second pressures within a ventricle, said first and second pressures being temporally separated from each other; a non-invasive event detector for obtaining third data indicative of an occurrence of an event in the cardiac cycle; and a data processor configured to receive said first, second and third data and to combine said first and second data on the basis of said third data to construct therefrom, a ventricular pressure waveform. 20. The system of claim 19, wherein said data processor comprises a shifting process, said shifting process configured to temporally shift said first data on the basis of said second data. 21. The system of claim 20, wherein said data processor further comprises a calibration process, said calibration process configured to assign corresponding pressures to said first and second data. 22. The system of claim 19, wherein said non-invasive barograph comprises an atrial barograph. 23. The system of claim 22, wherein said atrial barograph comprises an apex cardiograph. 24. The system of claim 19, wherein said non-invasive barograph comprises an arterial barograph. 25. The system of claim 19 wherein said non-invasive event detector is selected from the group consisting of a phonocardiogram, a venous pulse acquisition unit, and an apex cardiograph. 26. The system of claim 19, wherein said non-invasive event detector comprises a venous pulse acquisition unit. 27. The system of claim 19, wherein said non-invasive event detector comprises an apex cardiogram.
