DEVICES, SYSTEMS, AND METHODS TO PRECONDITION, ARTERIALIZE AND/OR OCCLUDE A MAMMALIAN LUMINAL ORGAN
Devices, systems, and methods to precondition, arterialize, and/or occlude a mammalian luminal organ. In an exemplary embodiment of a device for preconditioning, arterializing, and/or occluding a mammalian luminal organ of the present disclosure, the device comprises a frame comprising a plurality of struts, wherein at least one strut of the plurality of struts forms a local general perimeter or boundary of the device, and an expandable occluder coupled to the frame and comprising a membrane or other expandable material that can generally expand and/or unfold as device shifts from a first configuration to a second configuration.
1 . A device for preconditioning, arterializing, and/or occluding a mammalian luminal organ, comprising:
a frame comprising a plurality of struts, wherein at least one strut of the plurality of struts forms a local general perimeter or boundary of the device; and
an expandable occluder coupled to the frame and comprising a membrane or other expandable material that can generally expand and/or unfold as device shifts from a first configuration to a second configuration.

3 . The device of claim 1 , wherein the first configuration is a generally compressed configuration, and wherein the second configuration is a generally expanded or deployed configuration.
4 . (canceled)
5 . (canceled)
6 . The device of claim 1 , wherein the expandable occluder is located at or near a distal end of the device.
7 . The device of claim 1 , wherein the expandable occluder is located at a relative center/middle of the device.
8 . (canceled)
9 . The device of claim 1 , wherein the expandable occluder comprises a biologically-compatible material.
10 . The device of claim 9 , wherein the biologically-compatible material comprises polytetrafluoroethylene (PTFE).
11 . The device of claim 1 , wherein the expandable occluder comprises a biological material.
12 .- 14 . (canceled)
15 . The device of claim 1 , wherein the plurality of struts includes at least one perimeter strut and/or at least one lateral strut.
16 . (canceled)
17 . The device of claim 1 , wherein the plurality of struts includes at least three perimeter struts, and wherein the expandable occluder is coupled to the frame at a most distal of the at least three perimeter struts.
18 . The device of claim 1 , wherein at least part of the device tapers from a first end to an opposite second end.
19 . The device of claim 1 , wherein the plurality of struts comprises a first perimeter strut, a second perimeter strut, and a third perimeter strut, wherein a first gap exists between the first perimeter strut and the second perimeter strut, wherein a second gap exists between the second perimeter strut and the third perimeter strut, and wherein the first gap is larger than the second gap.
20 .- 37 . (canceled)
38 . A method of using a device, comprising the steps of:
inserting a device of the present disclosure within a non-arterial luminal organ, the device comprising:
a frame comprising a plurality of struts, wherein at least one strut of the plurality of struts forms a local general perimeter or boundary of the device, and
an expandable occluder coupled to the frame and comprising a membrane or other expandable material that can generally expand and/or unfold as device shifts from a first, collapsed configuration to a second, expanded configuration; and
expanding the device from a first, collapsed configuration to a second, expanded configuration to anchor the device within the non-arterial luminal organ;
wherein the device, when in the second, expanded configuration, is operable to block bodily fluid therethrough at the location of the expandable occluder.
39 . The method of claim 38 , wherein the device, when expanded and anchored in a vein, facilitates preconditioning of the vein prior to arterialization.
40 . (canceled)
41 . (canceled)
42 . The method of claim 38 , wherein when the device is expanded and anchored in a vein at a bifurcation having a first side branch and a second side branch, blood can flow through the first side branch but not the second side branch.
43 . The method of claim 38 , wherein the device, when expanded and anchored in the non-arterial luminal organ, causes a localized stenosis at or near the expandable occluder.
44 .- 52 . (canceled)
53 . The method of claim 38 , further comprising the step of:
performing a medical procedure after the device is anchored within the non-arterial luminal organ.
54 .- 56 . (canceled)
57 . The method of claim 38 , wherein the plurality of struts includes at least two perimeter struts and at least one lateral strut, the at least one lateral strut connected to two of the at least two perimeter struts, and wherein the step of inserting is performed to insert the device within a non-arterial luminal organ at a bifurcation so that the bifurcation is located at the at least one lateral strut.
58 . A device for preconditioning, arterializing, and/or occluding a mammalian luminal organ, comprising:
a frame comprising a plurality of struts, wherein at least one strut of the plurality of struts forms a local general perimeter or boundary of the device; and
an expandable occluder coupled to the frame and comprising a membrane or other expandable material that can generally expand and/or unfold as device shifts from a first configuration to a second configuration;
wherein the first configuration is a generally compressed configuration, and wherein the second configuration is a generally expanded or deployed configuration;
wherein the first configuration allows the device to be delivered intravascularly within a patient; and
wherein the plurality of struts comprises a first perimeter strut, a second perimeter strut, and a third perimeter strut.
59 . The device of claim 58 , wherein a first gap exists between the first perimeter strut and the second perimeter strut, wherein a second gap exists between the second perimeter strut and the third perimeter strut, and wherein the first gap is larger than the second gap.
60 . The device of claim 58 , wherein the expandable occluder comprises a biological material selected from the group consisting of visceral pleura and lung ligament tissue.
