Title (EN) METERS FOR IN-VIVO MONITORING
(FR) COMPTEURS POUR SURVEILLANCE IN VIVO
Abstract:
(EN) Systems and methods for use in monitoring treatment of pressure-related conditions, such as hydrocephalus, include an implantable vessel, and a meter including one or more microfluidic channels connected to the vessel. The microfluidic channels may be configured to detect at least one of pressure and fluid flow rate through the vessel and to be read out remotely by a wirelessly coupled external device. The meter may include a passive resonant (LC) circuit. A dynamic flap may be included in the microfluidic channel that may act as part of the LC circuit. An external device may also be configured to inductively couple remotely to the LC circuit, without physical connections to the implantable vessel or pressure meter, and to display a pressure acting on the pressure meter andlor a fluid flow through the meter.
(FR) La présente invention concerne des systèmes et des procédés destinés à être utilisés dans la surveillance d'un traitement pour des pathologies liées à la pression, telles que l'hydrocéphalie, faisant appel à un récipient implantable et à un compteur comprenant un ou plusieurs canaux microfluidiques reliés au récipient. Lesdits canaux microfluidiques peuvent être conçus pour détecter une pression et/ou un débit de fluide à travers le récipient, et pour permettre une lecture à distance par un dispositif externe accouplé sans fil. Ledit compteur peut comprendre un circuit résonnant passif (LC). Une trappe dynamique peut être intégrée dans le canal microfluidique pour agir en tant que partie du circuit LC. Par ailleurs, un dispositif externe peut être conçu pour s'accoupler de manière inductive à distance au circuit LC, sans raccordements physiques au récipient implantable ni au pressiomètre, et pour afficher une pression agissant sur le pressiomètre et/ou un débit de fluide à travers le pressiomètre.
