Abstract

An example system for detecting leakage around an occlusive implant disposed in the left atrial appendage includes an elongate shaft having a port disposed at a distal end region thereof and a first sensor disposed adjacent the elongate shaft. The elongate shaft is configured to be positioned adjacent the occlusive implant such that the first sensor is positioned on a first side of the occlusive implant and the port is positioned on a second side of the occlusive implant. Further, the first sensor is configured to measure a first parameter and the first parameter is utilized to determine a fluid leak between the occlusive implant and a tissue wall defining the left atrial appendage.
