1. A method for engaging mitral valve leaflets, comprising:
- a) directing a distal end of an elongated catheter body of a leaflet-engaging device into a coronary sinus of a heart;
b) passing a first leaflet-engaging component located proximate to said distal end of said elongated catheter body of said leaflet-engaging device through cardiac tissue separating said coronary sinus and a left atrium of said heart to enter a left atrium of said heart; and
c) engaging a first mitral valve leaflet with said first leaflet-engaging component,thereby engaging at least one mitral valve leaflet.

Abstract
Disclosed are a method for engaging cardiac valve leaflets, including a) directing a distal end of an elongated catheter body of a leaflet-engaging device into a coronary sinus of a heart, b) passing a first leaflet-engaging component located proximate to the distal end of the elongated catheter body of the leaflet-engaging device through cardiac tissue separating the coronary sinus and a left atrium of the heart to enter a left atrium of the heart, and c) engaging a first cardiac valve leaflet with the first leaflet-engaging component, thereby engaging at least one cardiac valve leaflet. Related apparatus and methods are also described.

50. A device suitable for defining a minimally invasive conduit to a left atrium of a mammalian heart, comprising:
-
a) an elongated catheter body with a proximal end, a distal end and a distal tip, said distal end configured for passage into a coronary sinus from a peripheral region of a mammalian body; b) a main lumen passing from said proximal end to said distal end of said elongated catheter body, said main lumen terminating at a side port located at a side of said distal end of said elongated catheter body; c) a reversible anchoring component in proximity of said distal end of said elongated catheter body, said anchoring component having at least two states; i) a first non-anchoring state; and ii) a second anchoring state, wherein said anchoring component engages walls of a coronary sinus in which said distal end is located so as stabilize a position of said distal end in said coronary sinus; and d) an anchoring component actuator functionally associated with said anchoring component, configured to allow changing of said anchoring component from said first non-anchoring state to said second anchoring state, wherein said anchoring component is configured to anchor on a side of said elongated catheter body opposite said side port. - View Dependent Claims (51, 53, 54)
