Abstract: A catheter inner assembly includes a receptacle with an interior contour configured to mate with a head and neck contour of a holding member of an implantable medical device; and a laterally facing opening of the receptacle has a profile matching a longitudinal profile of the head and neck. Thus, the opening allows only a properly oriented passage of the holding member therethrough, the passage being without deformation of holding member or opening. The inner assembly further includes a lock and release member useful for securing the device to the catheter, when the holding member has been passed through the receptacle's opening to mate with the receptacle's interior contour. The lock and release member may include an arcuate sidewall moveable between a first location, at which the sidewall overlays the laterally facing opening, and a second location, at which the sidewall is located proximal to the opening.

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.

Abstract: An interventional medical system includes an elongate shaft, a steering assembly coupled to the shaft, a snare member, and a passageway configured to allow passage of the snare member therethrough and into a first longitudinally extending lumen of the shaft; wherein the passageway is spaced distally from the steering assembly actuator by no more than 3 cm to 3.5 cm, and the passageway includes an elastic sealing perimeter. The passageway may, in some cases, be formed in a tapered member of the steering assembly that couples a proximal end of the shaft to a core of the steering assembly.

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: A shaft of an interventional medical system catheter has a distal end formed by opposing elastically deformable retention features that protrude into a lumen of the shaft, and that define an expandable distal opening of the lumen. The retention features secure an implantable medical device to the catheter by an interlocking engagement within a gap defined by a necked-in portion of a device holding member. Each retention feature includes a distal-facing surface defining the distal opening, and, when an elongate release member of the catheter, which extends within the shaft lumen, applies a push force against proximal-facing surfaces of the features, the distal opening expands from a constricted to an open configuration, wherein the open configuration allows passage of the device holding member through the distal opening, and the constricted configuration allows for the interlocking engagement with the device.

Abstract: In an interventional medical system, a tethering member of a catheter assembly and a holding member of a relatively compact implantable medical device are configured to interlock with one another. The tethering member includes an elongate shaft portion and a connector portion coupled to a distal end of the shaft portion, wherein the connector portion is configured to pass through a proximal-facing opening of a cavity defined by the device holding member, and to interlock with the holding member within the cavity. The connector portion of the tethering member includes a lumen extending longitudinally therethrough, which has a distal opening in fluid communication with the cavity of the device holding member, when the connector portion interlocks therewith. The catheter assembly further includes an elongate mandrel, which has a distal tip configured to extend within the lumen of the tethering member connector portion, being in sliding engagement therewith.
