1. An implant delivery system, comprising:

  • an implantable device comprising a plurality of supports extending between a proximal end and a distal end, the supports each having a proximal end, a distal end, an intermediate portion between the proximal end and the distal end, and being configured and adapted to move between a collapsed configuration and an expanded configuration,wherein the proximal ends of the plurality of supports are joined at a proximal hub having a diameter smaller than a diameter of the plurality supports in the expanded configuration, anda catheter system including a catheter having a lumen within a distal end region thereof, wherein the catheter system is sized and adapted to contain at least a portion of the implantable device when the implantable device is in the collapsed configuration;

    an activation element slidable within the lumen of the catheter; and

    a disconnect mount releasably joining the implantable device and the catheter when the implantable device is in the collapsed configuration,wherein the disconnect mount comprises two or more flexible fingers extending distally with respect to the catheter,wherein the two or more flexible fingers are sized and adapted to engage the proximal hub of the implantable device in an outwardly flexed position,wherein the activation element when activated allows the two or more flexible fingers to return to a biased position and moves the implantable device between the collapsed configuration and the expanded configuration, andwherein the disconnect mount is adapted to release the implantable device thereby allowing the catheter and the activation element to be removed from a patient while the implantable device remains implanted within the patient.
