Abstract

An assembly including a deployment device for deploying a stent device into an aorta of a patient is provided. The deployment device includes a rod translatable within an aorta of a patient and a first release wire configured for releasing one or more radially constraining members, wherein the radially constraining members are configured to constrain a diameter of the stent device. The stent device is at least partially permeable and engaged with the deployment device in an initial configuration, wherein a diameter and a length of the stent device in a deployed configuration can be altered by axial translation of the rod and releasing one or more of the radially constraining members by translation of the first release wire.

Claims

1. An assembly comprising:

a deployment device having;

a rod translatable within an aorta of a patient and having an operator end and a distal end;

at least one release wire, a first one of the at least one release wire configured for releasing first and second radially constraining members, and

a stent device aimed with the deployment device in an initial configuration, the stent device having;

a distal portion for being engageably received in the aortic arch of the patient and extending beyond the left subclavian artery when implanted;

a stent portion fluidly engaged with the distal portion, the stent portion being at least partially permeable and configured to span a portion of the aortic arch including the brachiocephalic trunk, left common carotid artery, and left subclavian artery;

a proximal portion fluidly engaged with the stent portion and defining a collar for engagement with the aorta;

wherein the radially constraining members are configured to constrain a diameter of the stent device when engaged therewith,

wherein a diameter of the stent portion is altered axial when the first radial constraining member is released to allow expansion of a proximal segment of the stent device and when the second radially constraining member is released after the first radially constraining member is released to allow expansion of a segment of the stent device distal to the proximal segment;

wherein a length of the stent portion altered by translation of the rod when at least a portion of the stent device remains engaged with the deployment device during deployment of the stent device due to at least one radially constraining member being unreleased,

wherein, in operation, the collar is allowed to expand until engaged with a portion of the aorta during deployment of the stent device,

wherein the stein portion and distal portion are formed from an open cell, uncovered stent material so blood flows from the aorta into the brachiocephalic trunk;

left common carotid artery, and left subclavian artery when the stent device has been implanted.

2. The assembly according to claim 1, wherein the deployment device includes a handle assembly for providing axial translation of the rod.

3. The assembly according to claim 2, wherein the deployment device defines a first outlet from which the first release wire extends.

4. The assembly according to claim 3, further comprising a first cap selectively receivable by the first outlet, wherein the first release wire is engaged with the first cap.

5. The assembly according to claim 3, wherein the deployment device defines a second outlet from which a second one of the release wires extends, wherein the second one of the release wires is configured releasing additional one or name radially constraining members.

6. The assembly according to claim 1, wherein the deployment device defines a third outlet through which a guidewire extends, wherein the rod defines a tip on the distal end that has an initially non-linear arrangement, and wherein advancement of the guidewire through the tip causes the tip to define a linear arrangement.

7. The assembly according to claim 1, wherein each of the first and second radially constraining members include a slip joint.
