Motorized telescoping medical device delivery system

A system for delivering an implantable medical device, comprising:

• a handle housing;
• an outer sheath configured to cover at least a portion of the implantable medical device;
• an outer sheath coupler secured to the outer sheath such that translation of the outer sheath coupler relative to the handle housing causes translation of the outer sheath relative to the handle housing;
• an outer sheath nut threadedly disposed on a first threaded rod and operably coupled to the outer sheath coupler;
• an outer sheath drive motor operably coupled to the outer sheath nut such that actuation of the outer sheath drive motor causes the outer sheath nut to translate relative to the first threaded rod and thus causes the outer sheath coupler to translate relative to the handle housing;
• an actuation shaft extending within the outer sheath and operably coupled to translation members secured relative to the implantable medical device such that translation of the actuation shaft causes translation of the translation members which in turn causes the implantable medical device to shift from a delivery configuration to a deployment configuration;
• an actuation shaft coupler secured to the actuation shaft such that translation of the actuation shaft coupler relative to the handle housing causes translation of the actuation shaft relative to the handle housing;
• an actuation shaft nut threadedly disposed on a second threaded rod and operably coupled to the actuation shaft coupler;
• an actuation shaft drive motor operably coupled to the actuation shaft nut such that actuation of the actuation shaft drive motor causes the actuation shaft nut to translate relative to the second threaded rod and thus causes the actuation shaft coupler to translate relative to the handle housing;
• and
• a first thrust bearing configured to secure the first threaded rod at an end away from the outer sheath drive motor while permitting the first threaded rod to rotate relative to the first thrust bearing.
