Abstract: A hollow catheter segment comprising a longitudinally extending slot region including a slot, at least one longitudinally backbone region and longitudinally extending intermediate regions between either adjacent backbone regions or between one of the backbone regions and the slot region, the slot and backbone regions being all disjoint from each other, the slot region, at least one backbone region and intermediate regions being all distributed circumferentially around the driving section. The catheter segment includes plurality of first and second slits extending radially therethrough and disjoint from each other, each first slit extending around the catheter segment between slot region first and second side edges and the second slits each extending between one of a backbone region first and second side edges and either a backbone region first or second side edges of an adjacent backbone region or the slot.

Abstract: A system for driving an helical anchor into biological tissue including concentric inner and outer drivers defining a driver passageway therebetween for mounting the helical anchor thereinto, the inner and outer drivers being axially rotatable and longitudinally fixed relative to each other. The inner driver includes a protrusion protruding in the driver passageway and configured for engaging the helical anchor to prevent pure translation of the anchor along the inner driver while allowing helical movements of the helical anchor relative to the inner driver. The outer driver is includes a slot extending therealong from an outer driver distal end towards an outer driver proximal end, the slot receiving the anchor protrusion thereinto and allowing movements of the anchor protrusion therealong. An actuator selectively rotates the inner and outer driver relatively to each other.
