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.

First claim

What is claimed is:

1. A delivery device for delivering a device within a lumen, the delivery device comprising:
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 and a deployment configuration; wherein when in the pre-deployment configuration the outer sheath covers the at least one delivery platform and wherein when in the deployment configuration the outer sheath exposes at least one of the at least one delivery platform so as to deploy at least one of the at least one intraluminal device;
a handle housing having a trigger operatively coupled to the outer sheath, wherein the trigger is configured to cause the outer sheath to withdraw from over the inner shaft and to facilitate movement of the outer sheath from the pre-deployment configuration to the deployment configuration;
an interlock engageable with at least one of the trigger, the outer sheath, and the inner shaft and having a locked position and an unlocked position, wherein the interlock is configured to substantially prevent movement of at least one of the inner shaft and the outer sheath with respect to the handle housing when in the locked position, and wherein the interlock is configured to allow movement of at least one of the inner shaft and the outer sheath with respect to the handle housing when in the unlocked position;
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
a cap moveable with respect to the housing and having a lock, wherein when locked the cap is configured to prevent the interlock from moving from the locked position to the unlocked position, and wherein when unlocked the cap is configured to allow the interlock to move from the locked position to the unlocked position, wherein the cap is rotatable with respect to the handle housing and fixed with respect to the handle housing in a proximal-distal direction.

2. The delivery device of claim 1 , wherein the inner shaft adjuster comprises at least one pin associated with the inner shaft, wherein the at least one pin is configured to extend through a portion of the handle housing.

3. The delivery device of claim 2 , wherein the cap is configured to mate with the at least one pin, and wherein cooperative motion of the cap and the at least one pin causes movement of the inner shaft.

4. The delivery device of claim 2 , wherein the cap has at least one inner helical grooves configured to mate with the at least one pin.

5. The delivery device of claim 4 , wherein the cap is configured to be rotated with respect to the handle housing, wherein rotation of the cap in a first direction causes the at least one pin to move in a distal direction and rotation of the cap in an opposite second direction causes the at least one pin to move in a proximal direction.

6. The delivery device of claim 5 , wherein movement of the at least one pin in the distal direction causes movement of the inner shaft in the distal direction and movement of the at least one pin in the proximal direction causes movement of the inner shaft on the proximal direction.

7. The delivery device of claim 2 , wherein the at least one pin extends through at least one opening in a wall of the handle housing and is configured to slide in at least one of a proximal direction and a distal direction within the at least one opening.

8. The delivery device of claim 7 , wherein the at least one opening comprises at least one elongate slot in the wall of the handle housing, wherein the at least one elongate slot extends in a substantially proximal-distal direction.

9. The delivery device of claim 1 , wherein the handle housing further comprises a proximal extension having at least one of a medial slot and a lateral slot, wherein the at least one of a medial slot and a lateral slot extend substantially in a proximal-distal direction.

10. The delivery device of claim 1 , wherein the cap comprises at least one helical groove on an inner surface of the cap.

11. The delivery device of claim 10 , wherein the at least one helical groove is configured to accept a protrusion associated with at least one of the handle housing, outer sheath, and the inner shaft, and wherein interaction of the at least one helical groove and the protrusion causes relative movement between the cap and at least one of the handle housing, outer sheath, and the inner shaft.

12. The delivery device of claim 1 , wherein a distal end of the interlock engages the trigger and a proximal end of the interlock engages the inner shaft.

13. A delivery device for delivering a device within a lumen, the delivery device comprising:
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 and a deployment configuration; wherein when in the pre-deployment configuration the outer sheath covers the at least one delivery platform and wherein when in the deployment configuration the outer sheath exposes at least one of the at least one delivery platform so as to deploy at least one of the at least one intraluminal device;
a handle housing having a trigger operatively coupled to the outer sheath, wherein the trigger is configured to cause the outer sheath to withdraw from over the inner shaft and to facilitate movement of the outer sheath from the pre-deployment configuration to the deployment configuration;
an interlock engageable with at least one of the trigger, the outer sheath, and the inner shaft and having a locked position and an unlocked position, wherein the interlock is configured to substantially prevent movement of at least one of the inner shaft and the outer sheath with respect to the handle housing when in the locked position, and wherein the interlock is configured to allow movement of at least one of the inner shaft and the outer sheath with respect to the handle housing when in the unlocked position;
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
a cap moveable with respect to the housing and having a lock, wherein when locked the cap is configured to prevent the interlock from moving from the locked position to the unlocked position, and wherein when unlocked the cap is configured to allow the interlock to move from the locked position to the unlocked position, wherein the cap is rotatable and comprises a lip having a window and the interlock comprises a proximal extension configured to reside inside the lip and to fit through the window, wherein when the proximal extension resides inside the lip the interlock is prevented from moving from the locked position to the unlocked position, and wherein when window is aligned with the proximal extension the interlock is allowed to move from the locked position to the unlocked position.
