Device for protection against blood-related disorders, notably thromboses, embolisms, vascular spasms, hemorrhages, hemopathies and the presence of abnormal elements in the blood
First Claim
1. Device for protection against at least one of the following blood coagulation related disorders:
- thromboses, embolisms, coagulapathies, hemorrhages, hemopathies, and abnormal cell elements in blood;
characterized by the fact that it comprises;
first implanted means for measuring continuously or periodically at least one value of a biological parameter likely to precede or accompany an impending blood coagulation related disorder or the occurrence of a blood coagulation related disorder, and comprising at least one presentation means adapted to be placed in or on a blood or lymphatic vessel or cavity for presenting to the surrounding blood or lymph a provoking means for actively and continuously provoking a local biological reaction of a factor related to blood coagulation, and a sensor means in or close to said presentation means for responding to the local reaction of the factor provoked by said presentation means,second implanted means for determining one or several thresholds to which the measured value of the parameter is compared,and third implanted means for detecting crossing of this threshold and for automatically releasing, into circulation, a suitable dose of one or several therapeutic agents for therapy of the blood coagulation disorder.

Abstract
Device for protection against blood-related disorders, notably thromboses, embolisms, vascular spasms, hemorrhages, hemopathies and the presence of abnormal elements in the blood. The device, which is completely implantable, has means (1, 14, 15) for the automatic measurement of biological parameters of the blood, particularly pertaining to blood crasis and/or hemodynamics and/or the myocardium and/or the arteries and/or components present in the blood, implanted observation means, threshold means for comparing the parameter measured value, and means which automatically deliver a suitable treatment, for example a fibrinolytic treatment. This device has means for acquisition and treatment of the cardiac rhythm.
