Medical system for treating a left atrial appendage

A medical system, comprising:

• a left atrial appendage closure device including an expandable framework and a proximal hub disposed along a central longitudinal axis of the expandable framework, the expandable
• framework being configured to shift between a collapsed delivery configuration and an expanded deployed configuration;
• wherein the left atrial appendage closure device includes a sensor at least partially disposed within an interior of the expandable framework and axially movable relative to the proximal hub while the expandable framework is in the expanded deployed configuration, wherein the sensor is biased proximally;
• wherein the proximal hub includes a first threaded connection structure;
• and a delivery catheter including a core wire extending axially within a lumen of the delivery catheter, the core wire having a second threaded connection structure at a distal end thereof configured to releasably engage the first threaded connection structure in an unreleased configuration;
• wherein the sensor includes an annular ledge extending radially outward from an outer surface of the sensor.
