First Claim
Patent Images
1. A two-piece stent combination for facilitating retrograde supply of oxygenated blood to heart tissue through a coronary sinus comprising:
- an arterializing stent having a leading end configured to be positioned in a left ventricle and a trailing end configured to be positioned in a coronary sinus, and a restricting covered stent having an underlying restricting stent and a covering, and having a coronary sinus distal end configured to be positioned in the coronary sinus, and a right atrial proximal end, and exhibiting a constriction between said coronary sinus distal end and said right atrial proximal end.

Abstract
The present invention contemplates a method for percutaneously providing oxygenated blood retrogradely from the left ventricle via coronary sinus to the heart tissue without a significant left-to-right shunt. The present invention contemplates a two-piece stent combination generally having an arterializing stent and a restricting covered stent.

27. A method for retrogradely supplying oxygenated blood from a left ventricle to heart tissue via a coronary sinus comprising:
-
puncturing a hole through said coronary sinus and a wall of said left ventricle, delivering an arterializing stent through said hole, wherein a leading end is placed in said left ventricle and a trailing end is placed in said coronary sinus, and delivering a restricting covered stent with a coronary sinus distal end positioned within said coronary sinus. - View Dependent Claims (28, 29, 30, 31, 32, 33, 34, 35, 36)
