Tissue plug
Tissue plugs for occlusion of hollow anatomical structures and methods for their use are provided.
1. A device for treatment of hollow anatomical structures comprising:
a. a first portion;
b. a second portion;
c. an axial member configured to be oriented through a hollow anatomical structure and is connected to the first portion and the second portion;
d. at least one occluding member which adjusts upon said axial member to fill the hollow anatomical structure,
e. a first portion reinforcing element that is oriented substantially perpendicular to a longitudinal axis of the axial member;
f. a second portion reinforcing element;
g. a collar attached to at least one of the first and second portion reinforcing elements, and
h. a second axial member comprising an end portion advanceable to move the first portion away from the second portion and stretch the occluding member,
wherein the at least one of the first and second portion reinforcing elements is located between the collar and the at least one occluding member,
wherein the at least one occluding member is configured to adjust within the hollow anatomical structure upon longitudinal translation along the axial member,
wherein the first portion is either fixedly or slidably connected to the axial member and wherein the second portion is either fixedly or slidably connected to the axial member provided that the first portion and the second portion are not both fixedly attached to the axial member,
wherein said at least one occluding member is collapsible by tensioning the axial member from an initial state with an initial length to a deployed state with a length shorter than said initial length and wherein said deployed occluding member is configured to conform to the geometry of a tract formed by the hollow anatomical structure and comprises a material that is bunched and has loft to aid in filling the tract formed by the hollow anatomical structure,
wherein said first portion is an anchoring member which is expandable from an initial state with an initial diameter to a deployed state with a diameter greater than said initial diameter,
wherein the device is adapted for catheter delivery, and
wherein the device is adapted to be removed and redeployed.
2. The device of claim 1 wherein the first portion is in the form of a substantially planar anchoring member.
3. The device of claim 1 wherein the second portion is in the form of a fixed point or an anchoring member.
4. The device of claim 3 wherein the second portion is in the form of a substantially planar anchoring member.
5. The device of claim 1 wherein the at least one occluding member is bioabsorbable.
6. The device of claim 1 wherein said collar reduces the freedom of movement of any components which may move or slide along the axial member after deployment.
7. The device of claim 6 wherein said collar reduces the freedom of movement via chemical, mechanical or frictional means.
8. The device of claim 1 , wherein the material that has loft to aid in filling the hollow anatomical structure includes a web, a mesh, a foam, or a sponge construct.
9. The device of claim 1 , wherein the second axial member is a push rod.
10. A device for treatment of hollow anatomical structures comprising:
a. a first portion in the form of a substantially planar anchoring member;
b. a second portion;
c. an axial member configured to be oriented through a hollow anatomical structure and is connected to the first portion and the second portion;
d. at least one occluding member which adjusts upon said axial member to fill the hollow anatomical structure and comprises a material that is bunched and has loft to aid in filling the hollow anatomical structure,
e. a first portion reinforcing element that is oriented substantially perpendicular to a longitudinal axis of the axial member;
f. a second portion reinforcing element;
g. a collar attached to at least one of the first and second portion reinforcing elements, and
h. a second axial member comprising an end portion coupled to the first portion and advanceable to move the first portion away from the second portion and stretch the occluding member,
wherein the at least one of the first and second portion reinforcing elements is located between the collar and the at least one occluding member,
wherein the at least one occluding member is configured to adjust within the hollow anatomical structure upon longitudinal translation along the axial member,
wherein the device is adapted to be removed and redeployed, and
wherein the first portion is either fixedly or slidably connected to the axial member and wherein the second portion is either fixedly or slidably connected to the axial member provided that the first portion and the second portion are not both fixedly attached to the axial member.
11. The device of claim 10 , wherein said second portion is in the form of a substantially planar anchoring member.
12. The device of claim 10 , wherein said collar reduces the freedom of movement of any components which may move or slide along the axial member after deployment.
13. The device of claim 12 , wherein said collar reduces the freedom of movement via chemical, mechanical or frictional means.
14. The device of claim 10 , wherein the device is adapted for catheter delivery.
15. The device of claim 10 , wherein said at least one occluding member is collapsible from an initial state with an initial length to a deployed state with a length shorter than said initial length and wherein said deployed occluding member is configured to conform to the geometry of a tract formed by the hollow anatomical structure.
16. The device of claim 15 , wherein said first portion is expandable from an initial state with an initial diameter to a deployed state with a diameter greater than said initial diameter.
17. The device of claim 10 , wherein the at least one occluding member is bioabsorbable.
18. A device for treatment of hollow anatomical structures comprising:
a. a first portion in the form of a substantially planar anchoring member;
b. a second portion;
c. an axial member configured to be oriented through a hollow anatomical structure and is connected to the first portion and the second portion;
d. at least one occluding member which adjusts upon said axial member to fill the hollow anatomical structure,
e. a first portion reinforcing element that is oriented substantially perpendicular to a longitudinal axis of the axial member;
f. a second portion reinforcing element;
g. a collar attached to at least one of the first and second portion reinforcing elements, and
h. a second axial member comprising an end portion coupled to the first portion and advanceable to move the first portion away from the second portion and stretch the occluding member,
wherein the at least one of the first and second portion reinforcing elements is located between the collar and the at least one occluding member,
wherein the at least one occluding member is configured to adjust within the hollow anatomical structure upon longitudinal translation along the axial member,
wherein the device is adapted to be removed and redeployed, and
wherein said at least one occluding member is collapsible by tensioning the axial member from an initial state with an initial length to a deployed state with a length shorter than said initial length and wherein said deployed occluding member is configured to conform to the geometry of a tract formed by the hollow anatomical structure and comprises a material that is bunched and has loft to aid in filling the tract formed by the hollow anatomical structure.
