Abstract

A delivery system for an implantable medical device includes a tool and a tethering member extending side-by-side within an inner shaft thereof; the tool extends within a first lumen, being in sliding engagement therein, and includes a distal end coupling feature that protrudes from a distal end of the inner shaft; and the tethering member has a first segment extending within a second lumen, and a second segment extending from the first segment and distally from the distal end of the inner shaft to an end of the tethering member, which is configured to engage with a holding member of the device, and with which the coupling feature of the tool is configured to couple. A retainer may be joined to another end of the tethering member that protrudes from a proximal port of the system.
