Title:
IMPLANTABLE CARDIOVASCULAR PRESSURE SENSING SYSTEM AND METHODS OF USE
Document Type and Number:
WIPO Patent Application WO/2024/030883
Kind Code:
A3
Abstract:
An implantable cardiovascular pressure sensing system can be used to measure blood pressure accurately and safely without any patient intervention. It can include a pressure sensor that makes blood pressure measurements, circuitry for processing and storing the blood pressure measurements, and an antenna for transmitting the processed measurements to an external device (i.e., a device not implanted in the patient). The circuitry can average blood pressure measurements and/or remove artefacts caused by patient motion that is sensed with an accelerometer integrated into implantable cardiovascular pressure sensing system. A multilayer ceramic/polymer coating forms a hermetic seal around the components, preventing leakage or contamination. The implantable cardiovascular pressure sensing system is very versatile: it can be implanted in a blood vessel, next to a blood vessel, in an aneurysm sac, or integrated with another medical implant, such as an Amplatzer septal occluder, and implanted into or next to another vascular structure.
