Abstract: A method and system for performing transseptal extracorporeal membrane oxygenation is disclosed. The method may include puncturing a septum between the right atrium and the left atrium and advancing a catheter system through the puncture and into the aorta. A first portion of the catheter system can remove blood from the patient, in some examples near the inferior vena cava. A second portion can return oxygenated blood to the patient, through the transseptal puncture and into the aorta.

Abstract: Methods, apparatuses, and systems for performing a valve replacement or repair. Apparatuses may include systems and may include an outer catheter, one or more interchangeable inner catheters, a guidewire and an expandable chordae tendinae deflector. Also described herein are rapid pacing sheaths that may be used with any of these apparatuses and methods.

Abstract: Intravascular delivery system is designed for a safe and efficient access to secondary and tertiary vascular structures, such as the branches of the coronary sinus, to enhance the delivery and deployment of various catheters, such as, for example, pacemaker electrical leads. The over-the-wire system features a straight, or alternatively shaped, micro-catheter distal tip of an inner catheter that seamlessly cooperates with a peel-away reinforced outer catheter. The inner catheter and the peel-away reinforced outer catheter are advanced in their engaged mode of operation towards (or beyond) the target site. Subsequently, the inner and outer catheters are disengaged, and the inner catheter is removed from the outer catheter. A pacemaker lead may be advanced over the wire inside the outer catheter to the target site for deployment. Subsequently, the outer catheter is easily split and may be rapidly removed from the blood vessel.

Abstract: Methods, apparatuses, and systems for performing a valve replacement or repair. Apparatuses may include systems and may include an outer catheter, one or more interchangeable inner catheters and a guidewire. The inner catheter(s) may be detachably coupled to the outer catheter. The inner catheter and outer catheter may surround the guidewire such that the inner and outer catheters may be advanced in a monorail fashion within the patient. Example methods may include percutaneously inserting the outer and inner catheter(s) into an artery and advancing toward the right atrium, through a transseptal atrial puncture, and advanced to the left atrium and left ventricle to access the aortic valve.
