Locking release devices, systems, and methods

A system for delivering and/or deploying an implantable device, said system comprising:

• a flexible elongate member having a distal end with a delivery latch operably coupled therewith, and a proximal end opposite the distal end;
• a proximal control knob operably coupled with the proximal end of said flexible elongate member;
• a tubular flexible elongate member having a distal end with a lumen defined therein and a proximal end opposite the distal end;
• a distal control knob operably coupled with the proximal end of said tubular flexible elongate member;
• and
• a latch locking and release system shiftable between a locking configuration and a release configuration;
• wherein:
• said delivery latch is configured to engage a device latch on an implantable device;
• the lumen defined within the distal end of said tubular flexible elongate member is sized to extend over said delivery latch with a device latch engaged therewith to hold said delivery latch and the device latch in an engaged configuration;
• said latch locking and release system includes a tubular latch release mechanism sized, shaped, configured, and/or dimensioned to inhibit relative axial movement between said proximal control knob and said distal control knob when said latch locking and release system is in the locking configuration to maintain said delivery latch and the device latch in an engaged configuration;
• and
• in the release configuration, said latch release mechanism is sized, shaped, configured, and/or dimensioned to allow relative axial translation of said proximal control knob and said distal control knob along the longitudinal axis of said latch release mechanism to allow the delivery latch to be disengaged from the device latch.
