Devices and methods for intracardiac procedures
First Claim
1. A system for performing an interventional procedure in a heart within a patient'"'"'s chest, the chest being defined by a plurality of ribs and a sternum, the system comprising:
- a device for inducing cardioplegic arrest from outside the patient'"'"'s chest;
a blood circulation device for maintaining circulation of oxygenated blood in the patient'"'"'s arterial system downstream of the heart; and
an interventional device positionable through a percutaneous penetration between two adjacent ribs and through a penetration in a wall of the heart for performing a surgical intervention within the heart, the interventional device being configured for manipulation entirely from outside the chest, the intervensional device also including a replacement valve, a valve delivery device, and an elongate handle, the replacement valve being configured to be positioned into the chest through a percutaneous penetration between two adjacent ribs, the valve delivery device being couplable to the replacement valve and configured for positioning the replacement valve between the ribs and into the heart, the elongated handle having distal and proximal ends, the distal end having a coupling configured to releasably hold the replacement valve, the coupling being pivotable relative to the handle.

Abstract
The invention provides devices and methods for performing less-invasive surgical procedures within an organ or vessel. In an exemplary embodiment, the invention provides a method of closed-chest surgical intervention within an internal cavity of a patient'"'"'s heart or great vessel. According to the method, the patient'"'"'s heart is arrested and cardiopulmonary bypass is established. A scope extending through a percutaneous intercostal penetration in the patient'"'"'s chest is used to view an internal portion of the patient'"'"'s chest. An internal penetration is formed in a wall of the heart or great vessel using cutting means introduced through a percutaneous penetration in an intercostal space in the patient'"'"'s chest. An interventional tool is then introduced, usually through a cannula positioned in a percutaneous intercostal penetration. The interventional tool is inserted through the internal penetration in the heart or great vessel to perform a surgical procedure within the internal cavity under visualization by means of the scope. In a preferred embodiment, a cutting tool is introduced into the patient'"'"'s left atrium from a right portion of the patient'"'"'s chest to remove the patient'"'"'s mitral valve. A replacement valve is then introduced through an intercostal space in the right portion of the chest and through the internal penetration in the heart, and the replacement valve is attached in the mitral valve position.
