AI Technical Summary
Existing transvascular techniques for repairing damaged heart valves, such as the mitral valve, are limited by the inability to precisely position and deploy prosthetic devices due to the complex anatomy of the heart, particularly the mitral valve's D-shaped orifice and the challenges of navigating the delivery catheter through the septum to the left atrium.
A steerable catheter with a distal and proximal flexible portion, controlled by offset pull wires, allowing for a counterflexing configuration that enables precise positioning and deployment of prosthetic devices by creating a 'question mark' shape, facilitating better alignment with the mitral valve and reducing the gap between the catheter end and the valve annulus.
Enhances the ability to accurately position and deploy prosthetic devices at the mitral valve, reducing procedural complexity and improving the efficacy of valve repair by minimizing regurgitation through better alignment and spacing adjustments.
