Abstract:
A device for creating a plurality of myocardial channels comprising:an elongate tube having a distal port;an anchoring member slidably disposed within said elongate tube, said anchoring member having a pointed distal end extending from said elongate tube distal port, said pointed distal end adapted to penetrate into said myocardium;a treatment member slidably disposed within said elongate tube, said treatment member having an arcuate distal region having a cutting tip thereon, said arcuate distal region being biased to increase in radius when not constrained within said tube, such that said distally extending said elongate tube causes said treatment member distal end to decrease in radial distance from said anchor member and proximally retracting said elongate tube causes said treatment member distal end to increase in radial distance from said anchor member.
