Minimally invasive repair of heart valve leaflets

Abstract

A method of repairing a heart valve provides intravascular access for repair of a heart valve through a ventricular trans-septal approach. An external guide catheter can be inserted through a vein of a patient into the right ventricle via the right atrium. An internal guide catheter can be inserted through the external guide and can provide access to the septum for a puncture tool to create an opening through the septum to the left ventricle. The internal guide can then be advanced into the left ventricle and used to guide a deployment catheter that deploys a repair device onto the heart valve.

AI Technical Summary

Benefits of technology

The patent describes a deployment catheter that can release multiple sutures in a single activation, reducing the number of instrument exchanges and improving control of suture position. The sutures can also be used to deliver a biomatrix patch to enhance closure of the mitral valve. This patch can improve leaflet coaptation and reduce or eliminate mitral valve regurgitation by supporting the native leaflet tissue structure.

Problems solved by technology

The technical problem addressed in this patent text is the need for a minimally invasive system to repair heart valves while the heart is still beating, as current open heart surgery procedures are traumatic and require a sternotomy or right thoracotomy. The use of a robotically guided, thoracoscopically assisted cardiotomy is also discussed. The patent text describes a method and apparatus for minimally invasive surgery to repair heart valves while the heart is still beating.
