CARDIOVASCULAR ACCESS AND DEVICE DELIVERY SYSTEM
First Claim
1. A system for accessing a heart of a patient, comprising:
- a cardiac access sheath having a channel therein and a distal end configured to be advanced through a apical wall of the heart to provide direct access via the channel through the apical wall to the left ventricle;
a vascular access catheter having a distal end configured to be advanced through the skin and into a peripheral blood vessel; and
a rail having a first end configured to be inserted into the patient through the channel of the cardiac access sheath or through the vascular access catheter, the rail having an intermediate portion and a second end opposite the first end, the first end configured to be disposed outside a patient through a first percutaneous access site while the intermediate portion is disposed in a chamber of the heart and while the second end is disposed outside the patient through a second percutaneous access site.

Abstract
A system and method of accessing a heart of a patient is provided. A cardiac access channel is established through an apical wall of the heart to provide direct access through the apical wall to the left ventricle. A vascular access channel is established through the skin to a peripheral blood vessel. A first end of an elongate member is advanced from the outside of the apical wall through the cardiac access channel and into the left ventricle. A second end disposed opposite the first end remains outside the patient. The elongate member is drawn into and through the vascular access channel to externalize the first end of the elongate member while leaving the second end outside the apical wall of the heart.

8. A device for closing a cardiac access channel, comprising:
-
an elongate body having a proximal end and a distal end; the proximal end having a first opening for delivering a closure medium and a second opening for delivering a pressurizing medium; the distal end having a first fillable member comprising a distal face, an enclosure disposed at the distal face and extending proximally therefrom, and one or more pores disposed through the enclosure at the distal face thereof, the first fillable member being in fluid communication with the first opening such that the closure medium can be delivered to the first fillable member; the distal end having a second fillable member in fluid communication with the second opening such that the pressuring medium can be delivered to the second fillable member; wherein the first and second fillable members are arranged such that when the first fillable member contains the closure medium and the second fillable member contains the pressurizing medium, the closure medium is disposed through the pore(s). - View Dependent Claims (9, 10, 11)

12. A method of accessing a heart of a patient, comprising:
-
(a) establishing a cardiac access channel through a apical wall of the heart to provide direct access through the apical wall to the left ventricle; (b) establishing a vascular access channel through the skin to a peripheral artery; (c) advancing a first end of an elongate member from the outside of the apical wall through the cardiac access channel and into the left ventricle, a second end disposed opposite the first end remaining outside the patient; and (d) drawing the elongate member into and through the vascular access channel to externalize the first end of the elongate member outside of the peripheral artery while leaving the second end outside the apical wall of the heart. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23)

27. A method of placing a cardiovascular prosthesis, comprising:
-
advancing a delivery system percutaneously from a peripheral blood vessel access site into the left atrium of a heart; accessing the left ventricle from outside the heart through the wall of the heart at or adjacent to the apex of the heart by placing a sheath therethrough; delivering an elongate member through the sheath across the aortic valve; linking the delivery system with the elongate member to provide a venous-arterial rail for delivery of a prosthesis into the heart and/or the aorta; and treating a condition of the aortic valve or a condition in the arterial vasculature over the venous-arterial rail. - View Dependent Claims (28, 29, 30, 31, 32)
