Abstract

A device for placement in the aortic arch of a patient is provided. The device includes a distal portion for being engageably received in an aortic arch of a patient beyond the left subclavian artery and a stent portion fluidly engaged with the distal portion, the stent portion being permeable and configured to span a portion of the aortic arches to which the brachiocephalic trunk, left common carotid artery, and left subclavian artery attach to the aortic arch. A diameter of the stent portion may be modified by translation of the proximal portion to thereby alter a length of the stent portion thus causing modification of the diameter of the stent portion to fit anatomical features of differing dimensions.

Claims

1. A kit comprising:

a stent device for placement in the aorta arch of a patient, wherein a diameter of the stent device may be modified by translation of an end of the stent device to thereby alter a length thereof causing modification of the diameter of the stent device,

wherein the stent device comprises;

a distal stent portion that is permeable,

wherein the distal stent portion is a wireframe assembly that defines a circumferential periphery that spans but does not extend into the brachiocephalic artery, left common carotid artery, and left subclavian artery when placed within the aortic arch of a patient; and

a proximal portion that is impermeable and having a constraining member for constraining a diameter thereof,

wherein the proximal portion engages the distal stent portion at respective ends thereof such that the proximal portion is spaced-apart from the distant stent portion; and

a deployment apparatus comprising a sheath for housing the stent device and having a guide rod passing through a center therethrough for deploying the stent device at an operational site,

wherein the sheath constrains the distal portion of the stent device in a compressed state,

wherein the constraining member constrains the proximal portion of the stent device in a compressed state after removal of the sheath until release of the constraining member, and

wherein the guide rod carries the stent device and is removable through a center of the stent device when the stent device is in an expanded state and positioned within the aortic arch of the patient upon removal of the sheath.

2. The kit of claim 1, wherein the stent device includes at least one eyelet on a first end facing an operator, and the deployment apparatus further includes a pawl that is configured to engage the eyelet to expand and contract the end of the stent device to thereby shorten and elongate the stent device.

3. The kit of claim 2, wherein the pawl is initially retracted to contract the end of the stent device.

4. The kit of claim 3, wherein the pawl is initially retracted by a sleeve extending thereabout and the sleeve is translatable away from the pawl to thereby expand the pawl.

5. The kit of claim 3, wherein the pawl and the sleeve are translatable relative to the guide rod to alter one or more dimensions of the stent device.

6. The kit of claim 1, further including a guide wire extending through the guide rod and through a bumper on a second end opposed to the operator.

7. The kit of claim 6, wherein the proximal portion is covered with graft material.

8. The kit of claim 7, wherein the proximal portion covered with graft material includes a supporting wire frame.

9. The kit of claim 6, wherein the second end is telescopically engaged with a prosthetic device engaged in an adjacent anatomical organ.

10. The kit of claim 1, wherein the guide rod has a major external diameter that is about equal to an interior diameter of the stent device in the compressed state.

11. The kit of claim 10, wherein the prosthetic device is a transcatheter stent valve.
