Abstract: Aspects of the disclosure provide a delivery device including a handle assembly as well as an inner catheter connected to the handle assembly. The inner catheter has a distal portion configured to receive an implant. The delivery device further includes an outer catheter connected to the handle assembly and coaxially positioned over the inner catheter. The delivery device also includes a capsule assembly including a proximal capsule secured to a distal end of the inner catheter. The capsule assembly also includes a distal capsule connected to a capsule shaft that extends within the inner catheter, the capsule shaft interconnecting the distal capsule to the handle assembly. The capsule assembly includes engagement features to releasably secure the distal capsule to the proximal capsule. Methods of loading and releasing an implant from a delivery device are also disclosed.
