When transesophageal echocardiography is used to obtain a transgastric short axis view of the left ventricle of the heart, the best place to position the transducer is in the fundus of the stomach, aimed up through the left ventricle. The probes disclosed herein facilitate placement of the transducer in the optimum position within the fundus, despite wide variations in the distance between the lower esophageal sphincter and the fundus among different subjects. In one preferred embodiment, the ultrasound probe uses a bending section with a series of vertebrae and stiffening that is more flexible proximally and less flexible distally, which causes the probe to bend relatively sharply at the point where the probe exits the lower esophageal sphincter.
Pour exécuter une échocardiographie transoesophagienne afin d'obtenir une vue du ventricule gauche selon le petit axe transgastrique, le meilleur emplacement pour placer le transducteur dirigé vers ledit ventricule, est le fundus stomacal. La sonde objet de l'invention facilite la mise en place du transducteur dans la position optimale à 'intérieur du fundus quelque soit la distance, variable selon les individus, séparant le sphincter oesophagien inférieur du fundus. Dans une exécution préférée, la sonde à ultrasons comporte une section recourbable comprenant plusieurs nervures et raidisseurs, et plus flexible côté proximal et moins côté distal, qui oblige la sonde à se recourber assez fortement au point où elle sort du sphincter oesophagien inférieur.
