Abstract
A system for implanting a flow modifying device in a heart comprises a flow modifying device comprising a tubular body comprising first and second openings located at first and second ends of the tubular body and a neck positioned between the first opening and the second opening, and a guide catheter comprising a flexible elongate shaft comprising a proximal portion comprising a fitting for receiving an insertion instrument and distal portion comprising an enlarged distal tip to prevent the flexible elongate shaft from passing through the flow modifying device. A guide catheter for cannulating a coronary sinus from a superior vena cava comprises a pre-formed distal portion comprising a proximal straight zone, a proximal curved zone extending along a first curved path, a distal straight zone extending along a straight path and a distal curved zone extending along a second curved path. The guide catheter can have different stiffnesses.
