Abstract: A fluid cooled mold plate is disclosed. The fluid cooled mold plate has a front side, a rear side, and a perimeter that extends between its front and rear sides. A cooling chamber is formed within the mold plate. The cooling chamber has a front wall, a rear wall, and a perimeter wall that extends between the front and rear walls. An inlet fluid duct extends from a first side of the mold plate perimeter to a first end of the cooling chamber and an outlet fluid duct extends from a second side of the mold plate perimeter to a second end of the cooling chamber. The cooling chamber is occupied by a turbulence generating dispersion mesh that is secured between the front and rear walls the cooling chamber.

Abstract: A system for assessing blood circulation in a subject's limb, including detection means for detecting a signal dependent upon the arterial blood volume in a limb of the subject when the subject is in a first posture and also when the subject is in a second posture, different to the first posture; and processing means for calculating a quantitative indicator that is dependent upon the ratio of the signal for the first posture to the signal for the second posture.

Abstract: A post-operative, arterial patency monitoring system for monitoring patency of an artery of a limb including: a first probe positioned adjacent a first tissue area of a limb for producing first output signals dependent upon a first arterial blood supply to the first tissue area; a second probe positioned adjacent a second different tissue area of the limb for producing second, different output signals dependent upon a second arterial blood supply to the second tissue area; and means for processing the first output signals to produce a first arterial blood supply metric for the first arterial blood supply and a second, different, arterial blood supply metric for the first arterial blood supply; means for processing the second output signals to produce the first arterial blood supply metric for the second arterial blood supply and the second arterial blood supply metric for the second arterial blood supply; means for using a predetermined function that takes as its arguments at least the first and second arteri

Abstract: A method of non-invasively measuring venous oxygen saturation, comprising: applying a pressure transducer at a first site on a body, applying a drive signal to the external pressure transducer at a predetermined frequency, to cause a series of pulsations of a predetermined magnitude in the venous blood volume in the vicinity of said first site, applying an oximeter device at a second site on the body, measuring output signals received from said oximeter device, said output signals containing a component representative of the modulation of venous blood volume due to said pulsations, deriving a measure of venous oxygen saturation from the frequency response of said output signals.

Abstract: The present invention relates to an apparatus and to a method for the measurement of dimensions of biological structures. In particular, but not exclusively, the invention relates to the measurement of changes over time in the physical dimensions of tubular biological structures such as blood vessels in response to stimuli such as hormones, agonists, potential drugs. The method may be used in determining the effect of a gene.
