AORTIC LEAFLET REPAIR USING SHOCK WAVE APPLICATORS

Described herein are shock wave devices and methods for the treatment of calcified heart valves. One variation of a shock wave device (100) may comprise an elongated flexible tube (110A-C) carried by a sheath (108). The tube (110A-C) may have a fluid input end, which may be located near a proximal e...

Zusammenfassung:Described herein are shock wave devices and methods for the treatment of calcified heart valves. One variation of a shock wave device (100) may comprise an elongated flexible tube (110A-C) carried by a sheath (108). The tube (110A-C) may have a fluid input end, which may be located near a proximal end of the sheath (108). The tube (110A-C) may include a loop portion. The loop portion may be configured to be at least partially accommodated within a cusp of the heart valve (200). The tube (110A-C) may be fillable with a conductive fluid. In some variations, the shock wave device (100) may include an array of electrode pairs (330,334,338) associated with a plurality of wires positioned within the loop portion of a tube (110A-C). The electrode pairs (330,334,338) may be electrically connectable to a voltage source and configured to generate shock waves in the conductive fluid in response to voltage pulses.
