摘要:
A system for accurately locating and positioning a person moving or standing still inside a hostile or severely damaged environment. For a person walking through any given environment, the location system continuously provides coordinates for positioning the person within the environment relative to the entry point thereof. The location system uses the morphological data of the person and integrates the person's movement in real time by acquiring features of the person's pace as the result of simultaneously combining the angles formed by the ankles, knees and hips of the person when walking, measured by electrogoniometers and interpreted according to a developed calculation method. The location system outdoes other existing solutions for locating a person in a difficult environment, such as, inside an underground building, partially collapsed and filled with opaque smoke, without the risk of faulty measurements, since it does not track by waves or by any vision-based system.
摘要:
A method of moulding a bioresorbable polymer for producing a bioresorbable medical device includes the following successive steps: (a) heating a poly(1,4-dioxanone) in the absence of any solvent of this polymer to a mass temperature between 145° C. and 165° C., (b) injection moulding the molten mass obtained in step (a) in a mould which is at a temperature of 80° C. to 115° C. lower than the mass temperature of the poly(1,4-dioxanone), (c) cooling the mould until solidification of the mass of poly(1,4-dioxanone), and (d) removing the thus obtained part from the mould. Also described is a moulded part which can be obtained by such a method as well as a medical device containing such a part.
摘要:
An intraparietal reinforcement device (1) for use in a biological prosthesis (10), as well as a biological prosthesis (10) provided with a device of this type, is particularly suitable for use within the organic tissue of the biological prosthesis (10), and for reinforcing the structure of the prosthesis so that it retains its shape once implanted.
摘要:
An intraparietal reinforcing device is designed to be integrated into a biological valvular prosthesis consisting of a biological cardiac valve having a valve plane formed by leaflets attached laterally to an external wall along commissurae. The device can be placed in the organic tissue of the valve, and includes a base and a stabilizing part mounted thereon. The device can be inserted inside the external wall of the valve to reinforce the valve's structure and to maintain the valve's shape after implantation. The stabilizing part includes at least two intraparietal shafts, designed to be inserted into the valve tissue and positioned on the base so that, once the device is put in place on the valve, they are displaced laterally to the intersection point of the intersection line of the external wall with the commissurae and of the valve plane. A biological prosthesis may be provided with such a device.
摘要:
A device for shrinking and/or reinforcing the heart valve orifices includes a thick link (1) made of a bioresorbable, soft and curved material. It is secured at one of its ends to at least a thin yarn (3) whereof the end is fixed to a curved needle.
