Lens-invasive devices and methods for cardiac valve surgery
First Claim
1. A method of accessing an internal chamber of the heat 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:
- forming at least one percutaneous access port between at least one pair of adjacent ribs and positioning an instrument through a first access port of the at least one percutaneous access port and into an inner lumen of the vessel through a penetration in a wall thereof, a proximal end of the instrument extending out of the patient'"'"'s chest; and
manipulating the proximal end of the instrument to advance a distal end of the instrument through the vessel and into the internal chamber of the heart;
wherein all manipulations of the instrument are performed outside of the patient'"'"'s chest.

Abstract
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.
