AI Technical Summary
Technical Problem
The prior art requires the use of control fluid when detecting the left atrial appendage blockage, which has disadvantages such as allergic reactions, and cannot be detected without using the control fluid.
Method used
Using a system including a sheath, delivery system, medical tools, pressure sensors and processors, the presence or absence of blockage is determined by deploying medical tools in the left atrial appendix and detecting changes in blood pressure using pressure sensors.
Benefits of technology
It is possible to efficiently detect blockages in the left atrial atrium and other heart cavity or body parts without using control fluid, avoiding allergic reactions and other problems.
