Abstract

L'invention concerne un procédé et un dispositif permettant d'injecter des fluides dans des vaisseaux sanguins par perfusion sélective régulée par la pression vasculaire. Cette invention concerne notamment d'une part l'aspiration de fluide hors de veines, notamment dans des veines coronariennes, et la rétroperfusion de fluide dans des veines, les deux opérations étant régulées l'une comme l'autre par la pression veineuse, et d'autre part, la perfusion d'artères, notamment d'artères coronariennes, régulée par la pression artérielle. Le produit rétroperfusé est pompé dans le vaisseau sanguin (200) par l'intermédiaire d'un conduit flexible (60) ouvert à l'extrémité proximale et insérable dans une veine ou une artère (200) du patient. En cas de rétroperfusion de veines, le conduit (60) est raccordé à un dispositif (90) permettant d'aspirer du sang ou du produit rétroperfusé hors de la veine (200) du patient. Une unité de commande (10) synchronise, par l'intermédiaire de signaux fournis par ECG, les intervalles de pompage et d'aspiration avec le cycle cardiaque du patient. Pendant les phases de pompage, la pression intraveineuse ou intra-artérielle est mesurée et pendant les intervalles de pompage, l'unité de commande (10) maintient une pression vasculaire interne déterminée, aussi constante que possible, à l'aide d'un régulateur de débit (30).
