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.

Implantable apparatus includes two or more alignable marker elements, and systems and methods for manufacturing such implantable apparatus, and methods to utilize such implantable apparatus. For example, the implantable apparatus may include a first alignable marker element and a second alignable marker element that may be used to ensure proper alignment with a target site.

The present disclosure is directed to a shuttle apparatus for detachably joining a catheter to a guidewire so that the joined catheter, extending alongside the guidewire, is in sliding engagement with the guidewire without extending around the guidewire. The apparatus comprises a collar member sized for mounting in sliding engagement around a length of the guidewire, the collar member having a longitudinal axis that approximately aligns along the length, when mounted thereabout, the length being defined between a proximal-most point of the guidewire and a distal point of the guidewire, the distal point being offset proximally from a distal-most point of the guidewire. The apparatus further comprises a plug member coupled to the collar member, the plug member having a longitudinal axis, and the plug member being sized to fit within an opening of the catheter for detachable engagement therewith.

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.

A fixation mechanism of an implantable medical device is formed by a plurality of tines fixedly mounted around a perimeter of a distal end of the device. Each tine may be said to include a first segment fixedly attached to the device, a second segment extending from the first segment, and a third segment, to which the second segment extends. When the device is loaded in a lumen of a delivery tool and a rounded free distal end of each tine engages a sidewall that defines the lumen, to hold the tines in a spring-loaded condition, the first segment of each tine, which has a spring-biased pre-formed curvature, becomes relatively straightened, and the third segment of each tine, which is terminated by the free distal end, extends away from the axis of the device at an acute angle in a range from about 45 degrees to about 75 degrees.

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.

An example fixation component for an implantable medical device (IMD) includes a base and a plurality of tines configured be deployed with a target deployment stiffness to engage tissue a target implant site while maintaining a target deflection stiffness after deployment. The base defines a longitudinal axis of the fixation component and is fixedly attached near the distal end of the IMD. Each tine is spaced apart from one another around a perimeter of the distal end of the IMD and extend from the base. A shape of each tine is selected to control each of the target deployment stiffness and target deflection stiffness.
