Abstract: A multi-spiral, self-expanding stent is constructed from superposed individual spiral strands. Each spiral strand comprises a terminal bend that separates the strand into a first portion and a second portion. Particularly, the first portion of each strand bends in a first spiral direction to the terminal bend, and the second portion bends in the opposite direction after the terminal bend. Advantageously, the disclosed stent is able to change its shape, diameter, and length to accommodate the corresponding shape, diameter, and length of patient's diseased vessel.
Abstract: A device and method for repair of a patient's aorta is disclosed. The device includes a first component including an outer diameter equal to a first diameter, a second component attached to a distal end of the first component, and a plurality of third components positioned in a chamber defined in the second component. The second component includes a proximal surface extending outwardly from the distal end of the first component, and a plurality of openings defined in the proximal surface. Each third component includes a passageway extending inwardly from an opening of the plurality of openings defined in the proximal surface. Each passageway is sized to receive a tubular conduit, and the proximal surface has an outer edge that defines a second diameter greater than the first diameter.
Abstract: A method of deploying a stent device into an aorta of a patient includes positioning a distal portion of the stent device at least beyond the left subclavian artery into the descending aorta by axially translating a distal end of a rod of a deployment device into the aorta. The stent device is engaged with the deployment device in an initial configuration about the rod. The axial translation occurs in a direction extending from the aortic arch into the descending aorta. The stent device further includes a stent portion in fluid engagement with the distal portion. The stent portion and the distal portion define an uncovered open cell surface. The stent device further includes a proximal portion in fluid engagement with the stent portion. A collar is defined at a terminal end of the proximal portion.
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.
