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.

Claims20

Dependent claims

A method of deploying an intraluminal device, the method comprising:

advancing a distal portion of a delivery device to a treatment site, the delivery device comprising:
an inner shaft, the intraluminal device positioned around the inner shaft in the distal portion;
an outer sheath surrounding the inner shaft and the intraluminal device;
a handle housing comprising a spring loaded trigger operatively coupled to the outer sheath, the trigger configured to facilitate movement of the outer sheath with respect to the handle housing;
an interlock engageable with at least one of the trigger or the inner shaft, the interlock having a first position that inhibits movement of at least one of the inner shaft or the outer sheath with respect to the handle housing, the interlock having a second position that allows movement of the at least one of the inner shaft and the outer sheath with respect to the handle housing, the interlock configured to inhibit actuation of the trigger when the interlock is in the first position;
and
an inner shaft adjuster operatively coupled to the inner shaft;
operating the inner shaft adjuster to move the distal end of the outer sheath proximate to a distal end of the intraluminal device;
and
actuating the trigger to withdraw the outer sheath proximally by a length from over the inner shaft and the intraluminal device to allow the intraluminal device to self-expand at the treatment site.

A method of deploying an intraluminal device, the method comprising:

advancing a distal portion of a delivery device to a treatment site, the delivery device comprising:
an inner shaft, the intraluminal device positioned around the inner shaft in the distal portion, wherein the inner shaft is configured to travel between a first position and a second position distal to the first position, and wherein, during advancing the distal portion, the inner shaft is in the first position;
an outer sheath surrounding the inner shaft and the intraluminal device;
a handle housing having a spring loaded trigger operatively coupled to the outer sheath, the trigger configured to facilitate movement of the outer sheath with respect to the handle housing;
and
an inner shaft adjuster operatively coupled to the inner shaft;
operating the inner shaft adjuster to move the distal end of the outer sheath proximate to a distal end of the intraluminal device;
and
actuating the trigger to withdraw the outer sheath proximally by a length from over the inner shaft and the intraluminal device to allow the intraluminal device to self-expand at the treatment site.
