Delivery device and method of delivery
First Claim
1. A method of delivering at least one intraluminal device within a lumen, the method comprising:
- advancing a portion of a delivery device carrying at least one intraluminal device to a target volume, wherein the delivery device comprises;
an inner shaft having at least one delivery platform for deployment of at least one intraluminal device;
an outer sheath surrounding the inner shaft and having a pre-deployment configuration covering the at least one delivery platform and a deployment configuration exposing at least one of the at least one delivery platform;
a handle housing having a trigger operatively coupled to the outer sheath, the trigger being configured to facilitate movement of the outer sheath with respect to the handle housing;
an interlock engageable with at least one of the trigger and the inner shaft and having a locked position that substantially prevents movement of at least one of the inner shaft and the outer sheath with respect to the handle housing, and an unlocked position that allows movement of at least one of the inner shaft and the outer sheath with respect to the handle housing;
an inner shaft adjuster operatively coupled to the inner shaft and one or more of the handle housing and the interlock, wherein the inner shaft has a length of travel defined by a proximalmost position and a distalmost position, wherein prior to actuating the inner shaft adjuster to change the position of the inner shaft the inner shaft is in the proximalmost position;
arresting movement of the delivery device with respect to the target volume;
actuating the inner shaft adjuster to change a position of the inner shaft with respect to at least one of the handle housing and the outer sheath, wherein actuating the inner shaft adjuster to change the position of the inner shaft moves the inner shaft to its distalmost position and wherein the inner shaft must be in its distalmost position before the interlock can be moved from the locked position to the unlocked position;
moving the interlock from the locked position to the unlocked position so as to allow movement of at least the outer sheath with respect to the handle housing; and
actuating the trigger to withdraw the outer sheath proximally from over the inner shaft.

Abstract
A delivery device can include several different features including, at least: a shuttle and trigger retraction of an outer sheath; an interlock device to prevent actuation of the trigger; a retraction override switch and lock; and an inner shaft adjuster to ensure correct alignment of the inner shaft and the outer sheath prior to device deployment. The inner shaft adjuster may include, at least: a proximal portion of the handle housing having slots therethrough: pins operatively fixed to the inner shaft and extending through and slidable within the slots: and a cap having an inner helical groove that mates with the pins. Rotation of the cap may push the pins and the inner shaft in a proximal-distal direction. The cap may have a distal lip configured to accept a proximal extension of the interlock and retain it in a locked position until the inner shaft has been adjusted or moved.

12. A method of delivering at least one intraluminal device within a lumen, the method comprising:
-
advancing a portion of a delivery device to a target volume, wherein the delivery device comprises; an inner shaft having at least one delivery platform configured to hold at least one intraluminal device; an outer sheath surrounding the inner shaft and configured to move over the inner shaft in at least one of a proximal direction and a distal direction; a handle housing having a trigger configured to facilitate movement of the outer sheath; an interlock engageable with at least one of the trigger and the inner shaft and having a first position that substantially prevents movement of at least one of the inner shaft and the outer sheath with respect to the handle housing, and a second position that allows movement of at least one of the inner shaft and the outer sheath with respect to the handle housing; an inner shaft adjuster operatively coupled to the inner shaft and one or more of the handle housing and the interlock, wherein the inner shaft adjuster is configured to change a position of the inner shaft with respect to at least one of the handle housing and the outer sheath, and wherein the inner shaft adjuster is configured to lock the interlock until the inner shaft adjuster has changed the position of the inner shaft so as to prevent the interlock from moving from the first position to the second position, wherein the interlock comprises a proximal portion lockable by the inner shaft adjuster, wherein the inner shaft adjuster comprises a cap configured to rotate about the inner shaft while being substantially fixed in a proximal-distal direction, wherein the cap comprises at least one helical groove on an inner surface of the cap and a distal lip having a discontinuity; arresting movement of the delivery device with respect to the target volume; actuating the inner shaft adjuster to change the position of the inner shaft with respect to at least one of the handle housing and the outer sheath; unlocking the interlock; moving the interlock from the locked position to the unlocked position so as to allow movement of at least the outer sheath with respect to the handle housing; and moving the outer sheath with respect to the inner shaft. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20, 21, 22)
