AI Technical Summary
Technical Problem
Existing transcatheter procedures for heart valve modification, such as transcatheter mitral valve replacement (TMVR), face challenges in preventing left ventricle outflow tract (LVOT) obstruction by effectively cutting or modifying mitral valve leaflets without causing damage to neighboring tissues.
Method used
A heart valve tissue cutting device with a pivoted cutting guide arm and actuator wires, allowing controlled cutting or splitting of mitral valve leaflets by pivoting and protruding a blade through a slot, ensuring precise and smooth tissue modification.
Benefits of technology
Enables precise and controlled cutting of mitral valve leaflets, reducing the risk of LVOT obstruction and maintaining the integrity of the leaflet structure during transcatheter procedures.
