1. An implant comprising:
a pair of anchors, wherein an anchor of the pair of anchors comprises a proximal drive coupler extending along a drive axis; and
a cinch component configured to control a space between the pair of anchors and having a cinch drive coupler mounted coaxially with the proximal drive coupler for movement coaxially with the proximal drive coupler.
 
13. An implant delivery system comprising:
an implant comprising:
a pair of anchors, wherein an anchor of the pair of anchors comprises a proximal drive coupler extending along a drive axis; and
a cinch component; and
a delivery catheter comprising:
a cinch driver releasably coupled to the cinch component, the cinch driver operable, when actuated, along the drive axis to cause the cinch component to control a space between the pair of anchors, the cinch driver having a cinch driver lumen extending therethrough, the cinch driver lumen parallel to the drive axis; and
an anchor driver releasably coupled to the proximal drive coupler of an anchor of the pair of anchors, the anchor driver disposed within the cinch driver lumen.
 
19. A method of delivering an implant to a treatment site, the method comprising:
advancing the implant to the treatment site, the implant comprising a pair of anchors and a cinch component;
positioning the implant at the treatment site;
coupling an anchor drive shaft to one of the pair anchors;
actuating the anchor drive shaft about a drive axis to translate an anchor of the pair of anchors coaxially with the drive axis into the treatment site; and
actuating a cinch drive tube coaxially with the drive axis to actuate the cinch component to move coaxially with the drive axis to modify a space between the pair of anchors.
