ACTIVATION DEVICE FOR DYNAMIC RING MANIPULATION

摘要

An activation device for applying energy to an implanted annuloplasty ring is described. The activation device includes an outer elongate member having an outer elongate member distal end and an outer elongate member proximal end, and a lumen therebetween, wherein the inner elongate member is slidably insertable through the lumen of the outer member. The activation device further includes at least one adjustable spline having spline proximal and spline distal ends, the spline distal end connected to the inner tubular member distal end and the spline proximal end connected to the outer tubular member distal end, wherein the adjustable spline is configured to flex as the inner tubular member distal end is drawn proximally toward the outer tubular member distal end while the inner elongate member resides in the lumen of the outer elongate member. The activation device further includes at least one energy-transfer element coupled to the adjustable spline.
