Occlusive sealing sensor system

A system for detecting leakage around an occlusive implant disposed in the left atrial appendage, the system comprising:

• an elongate shaft having a first sensor disposed on a first portion thereof and a second sensor disposed along a second portion thereof;
• wherein 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 wherein the second sensor is positioned on a second side of the occlusive implant;
• wherein the first sensor is configured to measure a first parameter;
• wherein the second sensor is configured to measure a second parameter;
• wherein the first parameter is compared to the second parameter to determine a fluid leak between the occlusive implant and a tissue wall defining the left atrial appendage.

A method for detecting leakage around an occlusive implant disposed in the left atrial appendage, the method comprising:

• advancing an elongate shaft into the left atrial appendage, the elongate shaft including a first sensor disposed thereon and a port disposed at a distal end region thereof;
• positioning the elongate shaft 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;
• measuring a first parameter with the first sensor;
• utilizing the first parameter to determine a fluid leak between the occlusive implant and a tissue wall defining the left atrial appendage.
