Vessel closure system

A power driven vessel closure system for closing a hole in a wall of a body lumen, the vessel closure system comprising:

• a power source;
• a driver system operably couplable with the power source;
• an elongate drive member removably and operably couplable to the driver system;
• a drive collar operably coupled to the elongate drive member and movable relative to the elongate drive member;
• and
• a closure element associated with a surface of the drive collar configured to distally push the closure element, said closure element being retained in the vessel closure system in a deployment orientation and being capable of converting to a closed orientation when released from the vessel closure system into the wall of a body lumen so as to close the hole wherein the closure element is resilient from an open form in the deployment orientation to a closed form in the closed orientation when released from the vessel closure system.

A kit comprising:

• a power driven vessel closure system for closing a hole in a wall of a body lumen, the vessel closure system comprising:
• a fluid-tight modular handle comprising:
• a power source;
• and
• a power operated drive system operably coupled with the power source;
• and
• a plurality of disposable sheaths, each sheath having a proximal end being removably couplable with the handle, each sheath comprising:
• an elongate drive member having a proximal end that is removably and operably couplable with the power operated drive system;
• a closure element removably and operably coupled with the elongate drive member, said closure element being retained in the sheath in a storage orientation, and when said elongate drive member is operably coupled to the power operated drive system said elongate drive member is capable of distally moving the closure element within the sheath to the distal end of the elongate drive member and releasing the closure element from the elongate drive member and sheath into the wall of the body lumen so as to convert the closure element to a closed orientation and close the hole, wherein the closure element is resilient from an open form in the storage orientation to a closed form in the closed orientation when released from the vessel closure system;
• and
• a drive collar operatively coupled with the elongate drive member and the closure element, the drive collar being movable relative to the elongate drive member and including a pusher surface configured to push the closure element and to hold the closure element away from the sheath.
