Abstract: A delivery tool of a system for deploying medical diagnostics and/or therapy includes a deployment member and a sheath. An elastic cantilever element secured to a tubular sidewall of the deployment member, in proximity to a distal opening of a lumen formed by the sidewall, is spring biased to extend outward from the sidewall. When the cantilever element is received within the sheath, a sheath sidewall pushes the cantilever element inward, against the spring bias thereof, and a radius of curvature of the cantilever element approximately conforms to that of an outer surface of the deployment member sidewall. A helical track for receiving passage of a medical device helix fixation element therein may extend around a perimeter of the deployment member lumen, wherein a distal terminal end of the track is located in close proximity to the distal opening and generally opposite a free end of the cantilever element.
