Abstract:
A device for creating a plurality of myocardial channels in a heart chamber wall comprising:an elongate outer tube having a longitudinal axis, a proximal end, a distal end, a tubular wall and a distal region, said distal region wall having an elongate slot therethrough, said slot having a length; an elongate intermediate tube disposed within said outer tube, said intermediate tube having a wall, a distal region, and a channel in said distal region wall; and an elongate inner percutaneous myocardial revascularization cutting probe disposed within said intermediate tube and adapted to extend through said intermediate tube channel such that a distal length of said percutaneous myocardial revascularization cutting probe extends outside of said intermediate and outer tubes, wherein said percutaneous myocardial revascularization cutting probe extends at a longitudinal position relative to said outer tube, said outer tube slot having a proximal portion and a distal portion, said intermediate tube being slidable within said outer tube, said inner percutaneous myocardial revascularization cutting probe being slidable within said intermediate tube, such that said percutaneous myocardial revascularization probe extended distal length can be varied by sliding said inner percutaneous myocardial revascularization probe within said intermediate tube and through said intermediate tube channel, such that said percutaneous myocardial revascularization probe longitudinal position can be varied by sliding said intermediate tube within said slot, such that said percutaneous myocardial revascularization probe can be rotated by rotating said outer tube.
