    Abstract: A catheter proximal section is preferably formed from a relatively soft part and a relatively rigid part, and includes a proximal terminal end that defines a perimeter of an opening into a lumen of the catheter. The proximal section may further include a feature for interlocking engagement with an accessory tool. An inner surface of each of the relatively soft and rigid parts may be located opposite one another, on either side of the catheter lumen. The relatively soft and rigid parts may be included in a sealing assembly that further includes an attachment feature for removable connection of the assembly to the proximal section catheter.

    Abstract: Methods and systems for positioning a leadless pacing device (LPD) in cardiac tissue are disclosed. A delivery device is employed that comprises a proximal end, a distal end and a lumen therebetween sized to receive the LPD. The LPD has a leadlet extending therefrom that includes a means to fixate the leadlet to tissue. The delivery device comprises an introducer to introduce the LPD into the lumen of the delivery device. The LPD is loaded in the distal end of the lumen of the delivery device. The leadlet extends proximally from the LPD while the fixation means extends distally toward the LPD. A LPD mover is configured to advance the LPD out of the delivery device. A leadlet mover is configured to advance the leadlet out of the lumen delivery device and cause the leadlet to engage with cardiac tissue.

    Abstract: In some examples, a tether head assembly of a delivery system includes an inner retainer and an outer retainer that defines an aperture comprising a receptacle configured to receive an attachment member of a medical device, a passageway, and a groove. The inner retainer is movable within the groove between a second position in which the passageway is dimensioned to receive the attachment member and a first position in which the passageway is dimensioned to prevent passage of the attachment member. In some examples, a tether handle assembly defines a channel, a force transmitter within the channel, a slidable member partially received within a first end of the channel and a button partially received within a second end of the channel. Distally-directed force applied to the button may cause the force transmitter to apply proximally-directed force to the slidable member, moving the slidable member and an attached pull wire proximally.

    Abstract: A deflectable catheter includes an elongate member having a wall defining a longitudinally extending lumen extending from a proximal end to a distal end, a fixation member coupled to a distal portion of the elongate member, and a pull wire extending through the wall of the elongate member from the proximal end of the elongate member to the fixation member. The pull wire is coupled to the fixation member and constrained along its length such that the elongate member is configured to deflect from an initial configuration to a deflected configuration in response to a pull force applied to the pull wire and actively return from the deflected configuration to the initial configuration in response to a push force applied to the pull wire.

    Abstract: In some examples, a system includes a catheter comprising an elongated shaft defining a lumen, and a tether assembly. The tether assembly may include an elongate body, a tether head assembly attached to a distal end of the elongate body, where the tether head assembly includes an attachment mechanism configured to releasably attach to an attachment member of a medical device, and a positioning element fixedly positioned over the elongate body and configured to align the attachment mechanism with the attachment member when the tether head assembly is extended distally out of the lumen. The positioning element may include a distal end, a proximal end, and a length between the distal end and proximal end that is less than a length of the elongate body. The tether head assembly, elongate body, and positioning element may be movable within the lumen of the elongated shaft.

The inner retainer is movable within the groove between a second position in which the passageway is dimensioned to receive the attachment member and a first position in which the passageway is dimensioned to prevent passage of the attachment member. In some examples, a tether handle assembly defines a channel, a force transmitter within the channel, a slidable member partially received within a first end of the channel and a button partially received within a second end of the channel. Distally-directed force applied to the button may cause the force transmitter to apply proximally-directed force to the slidable member, moving the slidable member and an attached pull wire proximally.
