The symptoms of congenital heart failure are addressed in this surgical procedure for mounting a patch in the ventricle of the heart to reduce ventricular volume. Placement of the patch is facilitated by palpating a beating heart to identify akinetic, although normal appearing, tissue. The patch has an oval configuration facilitating return of the heart to a normal apical shape which enhances muscle fiber efficiency and a normal writhing pumping action. The patch includes a semi-rigid ring, and a circumferential rim to address bleeding. Patch placement is further enhanced by creating a Fontan neck and use of pledged sutures. Intraoperative vascularization and valve replacement is easily accommodated. Increased injection fraction, reduced muscle stress, improved myocardial protection, and ease of accurate patch placement are all achieved with this procedure.

The estimation of the variation of the glucose level in the blood of a person by the variation of the volume of the interstitial fluid compartments in muscular tissue due to a shift of fluid between the extracellular and intracellular compartments caused by variations of the osmotic pressure of the extracellular fluids which is in turn correlated with the glucose level. The variation of the volume of the interstitial fluid compartments is detected by a non-invasive conductometry measurement using electrodes placed in contact with the skin of the person overlying a portion of soft tissue including muscular fibers. To eliminate the adverse effect of the conductivity of the capillary vessels, the conductivity of the tissue is measured independently in two directions, namely parallel and transverse to the muscular fibers.

The present methods and systems relate to the automated determination of meat tenderness through the use of high-resolution imaging of meat surfaces. This imaging is performed at a resolution such that the ultra-structural organization of muscle fibers can be observed. Features are extracted from these images, which feature extraction can be aided by the use of texture analysis or wavelet analysis algorithms. In addition, observation of the colors of different areas or constituents of the muscle fibers can provide features. A laser scanner can be used instead of imaging methods, wherein data obtained from such scanner can be analyzed as linear waveforms, rather than two-dimensional arrays of information. These features are then used to estimate tenderness using decision algorithms.
