Abstract: A tool has an outer assembly, which includes a deployment tube, extending around, and moveable with respect to an inner assembly of the tool; the inner assembly includes a single pull wire and a distal member configured to engage an end of an implantable medical device. The deployment tube includes an articulating segment located just proximal to an enlarged distal-most portion, which contains the device and the distal member. Relatively soft and stiff sections of a composite sidewall define the articulating segment and extend alongside one another, such that, when the pull wire is actuated, the composite sidewall causes bending of the segment in two directions. A handle assembly of the tool includes a control member for the pull wire, and may further include a flushing subassembly that has a connector port located at an end of the handle assembly that is opposite a proximal port of the handle.

Abstract: An improved assembly for securing an implantable medical device for retrieval from an implant site includes a plurality of snares, wherein distal openings of a first snare carrier lumen and a second snare carrier lumen have a pre-set offset established therebetween. First and second snare shafts, to which first and second snare loops are coupled, respectively, extend within the corresponding snare carrier lumens such that each loop is located in proximity to the corresponding distal opening of the lumen. The pre-set offset allows an operator to simultaneously position the snare loops around the device; and, when the operator retracts the snare shafts to collapse the snare loops until the loops fit snuggly around the device, the pre-set offset can help to align the device for retrieval.
