Abrégé
(EN)
Devices, systems, and methods for the localization of body lumen junctions and other intraluminal structure are disclosed. Various embodiments permit clinicians to identify the locations of intraluminal structures and medical devices during non-surgical medical techniques, such as cardiac ablation, by determining the intralumen conductance and/or cross-sectional area at a plurality of locations within the body lumen.
(FR)
L'invention concerne des dispositifs, des systèmes et des procédés de localisation de jonctions de lumières corporelles et d'autres structures intraluminales. Divers modes de réalisation permettent aux cliniciens d'identifier les emplacements de structures intraluminales et de dispositifs médicaux au cours de techniques médicales non chirurgicales, par exemple une ablation cardiaque, par détermination de la conductance intraluminale et/ou de la zone transversale au niveau d'une pluralité d'emplacements de la lumière corporelle.
