Abstract: The disclosure describes techniques and systems for delivering an implantable medical device. In one example, an implantable medical device (IMD) delivery system may include an elongated member comprising a first distal end configured to mate with the IMD, a resilient member disposed along at least a portion of the elongated member, a housing configured to accept a first proximal end of the elongated member and a second proximal end of the resilient member, a rotation control mechanism wherein user movement of the rotation control mechanism causes rotation of the elongated member with respect to the housing and a fixation element of the IMD into tissue, and a deflection control mechanism wherein user movement of the deflection control mechanism causes longitudinal displacement of the resilient member along a longitudinal axis of the elongated member and the housing resulting in angular deflection of the first distal end of the elongated member.

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.

Abstract: A kit for implantation of an implantable medical device (IMD) comprises an elongated outer shaft, a tether, and an elongated inner shaft. The IMD comprises a fixation element comprising a looped portion. The outer shaft is sized to traverse a vasculature of the patient and defines a longitudinal lumen and a port in fluid communication with the lumen and located proximal a distal end of the outer shaft. A first portion of the tether is configured to pass through the lumen. A second portion of the tether is configured to exit the lumen through the port and pass through the looped portion of the fixation element of the IMD outside of the outer shaft. A third portion of the tether defines a looped portion of the tether. A portion of the inner shaft is configured to pass through the lumen and to pass through the looped portion of the tether.

Abstract: An engagement subassembly of a catheter, for retrieving an implanted medical device, may include at least three segments or, alternately, capture members being spring biased outward from a longitudinal axis of the subassembly, wherein a device receptacle of the catheter forces the capture members/segments, against the spring bias thereof, toward the axis. Each capture member includes a spring-biased wire and a grip, which is located between proximal and distal portions of the corresponding wire, and which is configured to interlock within a gap between a device attachment feature and housing; a length of each wire distal portion may be approximately equal to that of the device housing. An interlocking edge of each segment interlocks within the gap between the attachment feature and housing, when a distal-facing surface of each segment, which tapers outward from the axis in a distal direction, comes into confronting engagement with the device housing.

Abstract: In a system for retrieving an implanted device, a flared inner surface of a catheter tubular sidewall may define a distal-most opening of a device receptacle; the opening has a first diameter equal to that of the receptacle, and a second diameter, coincident with a distal-most edge of the tubular sidewall, and at least 5% greater than the receptacle diameter. Alternately, a retrieval tool in sliding engagement within a lumen of a catheter includes a shaft assembly, through which a snare member passes, and which includes a collapsible spring-biased perimeter sidewall; the sidewall defines a capture member passageway approximately coaxial, and in fluid communication with a lumen of the shaft assembly. A distal-most opening of the passageway has a spring-biased diameter that is greater than that of a distal-most opening of a device receptacle of the catheter, and a collapsed diameter that is less than the receptacle distal-most opening diameter.

Abstract: An inner member of an improved assembly for a delivery system includes a first segment formed by a multi-lumen tubing surrounded by a braided tubing, and a second segment formed by a single-lumen tubing that extends within a distal portion of the braided tubing. The single-lumen tubing accommodates an antenna of a medical device, is in fluid communication with three lumens of the multi-lumen tubing, and opens into a flared distal end of the inner member. A distal-most portion of an outer tube of the system contains the flared distal end and an enclosure of the medical device abutting the distal end. A pull wire of the assembly extends within another lumen of the multi-lumen tubing and between the single-lumen tubing and the distal extent of the braided tubing, and is coupled to a pull band mounted in a cone member that forms the flared distal end.

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: A tether holder has a locking portion, for securing a proximal end of a tether, and a pin portion that may fit within a receptacle of a handle assembly of a tool. A distal member of an inner assembly of the tool engages an implantable medical device, from which the tether extends, through at least one lumen of the inner assembly and out through a proximal port of the handle assembly, which is located in proximity to the receptacle. An enlarged distal-most portion of a deployment tube of the tool contains the distal member and the device, and is moveable, relatively to the inner assembly and the device, to deploy the device out through a distal opening of the tool. The handle assembly may also include a flush lumen and a tether engaging conduit, both in fluid communication with the at least one lumen of the inner assembly.

Abstract: A kit for intravascular implantation of an implantable medical device (IMD) within a patient includes the IMD, an elongated shaft, and a locking mandrel. The IMD comprises a fixation assembly comprising a loop and defines at least one longitudinal lumen and a port in fluid communication with the lumen. The shaft is sized to traverse a vasculature of the patient. The port is sized to receive at least a portion of the loop. The locking mandrel is configured to be positioned within the at least one lumen of the shaft and to pass through the loop within the lumen at the port. A reduced profile portion of the shaft defines a reduced profile with respect to at least one other portion of the shaft. At least a portion of the reduced profile portion is configured to be adjacent to the IMD when the IMD is positioned on the shaft.
