Systems and methods are disclosed for performing less-invasive surgical procedures within the heart. A method for less-invasive repair or replacement of a cardiac valve comprises placing an instrument through an intercostal access port and through a penetration in a wall of a vessel in communication with the heart, advancing the instrument into the heart, and using the instrument to perform a surgical intervention on a cardiac valve in the heart under visualization through an intercostal access port The surgeons hands are kept outside of the chest during each step. The surgical intervention may comprise replacing the cardiac valve with a prosthetic valve, wherein the native valve is removed using a tissue removal instrument, the native valve annulus is sized with a specialized sizing device, a prosthetic valve is introduced through an intercostal access port and through the penetration in the vessel, and the prosthetic valve is secured at the native valve position, all using instruments positioned through intercostal access ports without placing the hands inside the chest. Systems and devices for performing these procedures are also disclosed.
A method of accessing an internal chamber of the heart through a vessel having a lumen in fluid communication with the chamber, the heart and the vessel being within a patient's chest defined by a plurality of ribs connected to a sternum, the method comprising:
The method of claim I further comprising forming an incision in the vessel using a cutting tool manipulated from outside of the patient's chest.
In a valve replacement procedure, a method of positioning a replacement valve in a patient's heart within a patient's chest, the chest being defined by a plurality of ribs, the method comprising:
In a valve replacement procedure, a method of positioning a replacement valve in a patient's heart within a patient's chest, the chest being defined by a plurality of ribs, the method comprising:
An access device for providing a percutaneous passage into a chest cavity through which a replacement cardiac valve may be positioned, the access device comprising:
An access cannula for providing a percutaneous passage into a chest cavity through which a replacement cardiac valve may be positioned the access cannula comprising:
In a valve replacement procedure, a method of positioning a replacement valve in an aortic position of a patient's heart within a patient's chest, the aortic position being disposed between a left ventricle of the heart and an aorta leading away from the heart, the chest being defined by a plurality of ribs connected to a sternum, the method comprising:
