Deployment device

A stent graft deployment device, the device including:

• a tubular fixed handle to be gripped and held by a user;
• an elongate release handle extending through the fixed handle whereby the release handle can be moved through the fixed handle,
• a pusher at least partially disposed within the tubular fixed handle and the elongate release handle, the pusher comprising a hub;
• a release clamp positioned on the pusher, and
• a sheath to cover a stent graft disposed on the pusher,
• wherein the pusher is connected to the fixed handle and the sheath is connected to the release handle, whereby retraction of the release handle through the fixed handle causes the sheath to be retracted from the stent graft on the pusher,
• wherein a stop is disposed within an interior surface of the elongate release handle, the stop arranged to engage the release clamp on the pusher after a selected amount of movement of the elongate release handle has occurred, and
• wherein the release handle has longitudinal slots there along and an internal lumen, the pusher extends within the internal lumen, and wherein the pusher assembly includes arms which extend diametrically through the longitudinal slots to engage with the fixed handle, whereby the release handle can be moved with respect to the fixed handle to move the sheath with respect to the pusher.

A stent graft deployment device including:

• a handle, the handle including a tubular fixed handle to be gripped and held by a user and an elongate release handle extending through the fixed handle whereby the release handle can be moved through the fixed handle;
• a pusher at least partially disposed within the tubular fixed handle and the elongate release handle, the pusher comprising a hub;
• a release clamp positioned on the pusher;
• and
• a sheath to cover a stent graft on the pusher, the pusher being connected to the fixed handle and the sheath being connected to the release handle, whereby retraction of the release handle through the fixed handle causes the sheath to be retracted from a stent graft on the pusher wherein the fixed handle includes a grip component that grips the pusher and a rotator component that grips a release clamp on the pusher wherein the release clamp on the pusher has a trigger wire for the release of a stent graft from the pusher attached thereto and wherein the rotator component includes a screw thread with a portion of the release clamp engaged into the screw thread, whereby rotational movement of the rotator component causes longitudinal movement of the release clamp on the pusher thereby to pull the trigger wires, and
• wherein a stop is disposed within an interior surface of the elongate release handle, the stop arranged to engage the release clamp on the pusher after a selected amount of movement of the elongate release handle has occurred.
