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.

Abstract: A surgical instrument arrangement has a modular motor drive unit which has a drive arrangement having at least one output element, an instrument shaft that can be detachably connected to the drive unit, and a drive arrangement having at least one input drive element. The output drive arrangement and the input drive arrangement can be coupled to each other by a mechanical interface that has at least one single-sided linkage, a pin, and a cut-out, wherein the pin can be radially expanded in the cut-out. Alternatively, a gap may be formed between the pin and the cut-out, which gap is wavy in the radial direction, and in which a radially displaceable, axially fixed intermediate element arrangement is arranged. The surgical instrument arrangement may also include a sterile barrier, which is provided to envelop the drive unit and to be arranged between the drive unit and the instrument shaft.
