SYSTEMS FOR DEPLOYING MEDICAL DIAGNOSTICS AND/OR THERAPY AND DELIVERY TOOLS THEREOF
First Claim
1. A delivery tool for an implantable medical device, the tool comprising:
- a deployment member comprising a tubular sidewall and an elastic cantilever element, the tubular sidewall defining an elongate lumen of the deployment member that extends along a longitudinal axis of the tool, from a proximal opening of the lumen to a distal opening of the lumen, the lumen being configured to receive passage of an elongate body of the medical device therethrough, and the elastic cantilever element being secured to the tubular sidewall in proximity to the distal opening of the lumen, the cantilever element being spring biased to extend outward from the sidewall, in a direction approximately orthogonal to the longitudinal axis; and
a sheath including a tubular sidewall, the sheath sidewall defining an elongate lumen of the sheath that extends along the longitudinal axis of the tool, from a proximal opening of the sheath lumen to a distal opening of the sheath lumen, the sheath lumen being configured to receive passage of both the tubular sidewall of the deployment member and the elastic cantilever member of the deployment member therethrough; and
wherein the elastic cantilever element of the deployment member has a radius of curvature that approximately conforms to a curvature of an outer surface of the tubular sidewall of the deployment member, when the cantilever element is received within the sheath sidewall and the sheath sidewall pushes the cantilever element inward, toward the longitudinal axis, against the spring bias of the element.

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.
