A catheter for intravascular corporeal cooling comprises an elongated tubular member (12) having at least one lumen (26) extending therethrough for providing cooled blood, an inflatable annular balloon (16) positioned on the outer surface of the elongated tubular member (12), and a pressure reliever (32) positioned in the external wall (20) of the elongated tubular member (12) and proximal to the annular inflatable balloon (46), wherein when the pressure of blood within a lumen (26) reaches a predetermined value, the pressure reliever (32) opens to permit fluid to be released from the elongated tubular member (12). In other embodiments of the invention the catheter (40) may have two or more inflatable annular balloons (46) that are separately inflatable and/or the catheter (82) has an insulative outer annular member (84).
La présente invention concerne un cathéter, destiné au refroidissement intravasculaire corporel, comprenant un élément tubulaire allongé (12), comportant au moins une lumière (26) qui s'étend sur toute sa longueur, destiné au sang refroidi, un ballon annulaire gonflable (16) placé sur la surface extérieure de l'élément de tube allongé (12), et un orifice de réduction de pression (32) pratiqué dans la paroi extérieure (20) de l'élément tubulaire (12) et proche du ballon gonflable (46). Lorsque la pression sanguine dans une lumière (26) atteint une valeur prédéterminée, l'orifice de réduction de pression (32) s'ouvre afin de permettre au fluide de s'échapper de l'élément tubulaire allongé (12). Dans d'autres réalisations de l'invention, le cathéter (40) peut comporter deux ou plusieurs ballons annulaires (46), séparément gonflables, et/ou le cathéter (82) est doté d'un élément annulaire extérieur isolant (84).
