Abstract: A tool of an interventional medical systems system includes a core configured to be temporarily attached to the implantable medical device, as the tool deploys the device to expose a fixation member of the device for engagement with tissue at a target implant site; the core is then employed to verify adequate fixation of the deployed device via a tug test. An operator determines that the device is adequately fixed by the engaged fixation member, if a tug force that is applied to the core modifies the temporary attachment between the core and the device, to allow release of the device from the temporary attachment. A tether, which is fixedly attached to the core, may be employed to create the temporary attachment between the core and the device, or the temporary attachment may be created by a snap fit formed between the core and the attachment structure of the device.

Abstract: An inner subassembly of a delivery system assembly extends within a lumen of an elongate outer tube of the assembly, and includes a flared distal end, which is preferably configured to conform to a proximal end of an implantable medical device; a distal-most portion of the outer tube is sized to contain both the flared distal end and an entirety of the medical device. The inner subassembly includes a core, an elongate pull-wire, extending along the core, and a sheath surrounding the pull-wire and the core; the sheath includes a slot opening that allows the pull-wire to pass laterally therethrough. The assembly preferably has a pre-formed curvature along a length of the sheath, and the slot opening extends along the pre-formed curvature. The outer tube is longitudinally moveable relative to the inner subassembly, for example, to deploy the medical device.

Abstract: A delivery system assembly includes an elongate outer tube, an elongate inner member extending within a lumen of the outer tube, and an articulation sheath surrounding the outer tube between a handle of the assembly and a distal-most portion of the outer tube. The outer tube is longitudinally moveable within the sheath; and an inner diameter of the sheath is preferably smaller than that of the handle and the distal-most portion of the outer tube. Navigation of the assembly through a venous system, for deployment of an implantable medical device, is facilitated by deflection of the sheath, to orient a distal-most portion of the outer tube, within which an entirety of the medical device is contained/loaded, and by subsequent advancement of the distal-most portion, with respect to the sheath, to move the distal end of the inner member, along with the contained/loaded device into proximity with a target implant site.

Abstract: A delivery system assembly includes an outer tube, an inner member, extending within a lumen of the outer tube, and a deflectable shaft, extending within the outer tube lumen and around the inner member; the tube and inner member are longitudinally moveable with respect to the shaft, and a distal end of the inner member is located distal to the shaft within the tube lumen. A medical device can be loaded into the tube lumen, along a distal-most portion of the tube, and contained between the inner member and a distal opening of the tube lumen. Deflecting the shaft orients the distal-most portion for navigation of the assembly, and, when the distal end of the inner member is engaged within the tube lumen, distal movement of the tube, with respect to the shaft, causes similar distal movement of the inner member and the loaded medical device toward an implant site.

Abstract: A tether subassembly, which may be employed by a tool that deploys an implantable medical device, includes a test segment for verification of adequate fixation of the device at an implant site. When the device is located in proximity to a distal opening of the tube, a tether first length extends through an attachment structure of the device and within an elongate tube of the tool, a tether second length extends alongside the tether first length within the tube, and the test segment is located in proximity to the distal opening. The test segment is configured so that only a tug force, applied to the tether first length, and greater than or equal to a predetermined force, can pull the test segment through an aperture, either of the delivery tool or of the device. The predetermined force corresponds to a minimum adequate fixation force for the device.
