Textile engineered prosthetics, bioreactors, and methods of manufacturing textile engineered prosthetics
A textile engineered prosthetic includes a continuous tube and at least one band of increased thickness formed over a portion of the continuous tube. The continuous tube includes a body portion and a bifurcated portion. The band of increased thickness forms a biomimetic surface. A bioreactor system includes a bioreactor container including a first compartment, a second compartment, a first membrane separating the first and second compartments, a third compartment, and a second membrane separating the second and third compartments. The bioreactor system also includes a woven textile prosthetic integrated with the bioreactor container in the second compartment to form a single bioreactor unit. A furcated textile article includes a continuous tube having a body portion and a furcated portion bifurcated N times from the body portion. The furcated textile article is a continuous woven piece formed from N shuttles of a shuttle loom, where N is at least two.
1. A method of manufacturing a furcated textile article comprising:
weaving a continuous tube with a shuttle loom;
furcating the continuous tube into N portions, wherein N is at least two, where N is equal to a shuttle capacity of the shuttle loom;
forming at least one band of increased thickness formed over a portion of the continuous tube, wherein the at least one band of increased thickness forms a biomimetic surface; and
wherein the band is C-shaped.
2. The method of claim 1 , where N is at least three.
3. The method of claim 1 , where N is at least four.
4. The method of claim 1 , wherein the furcated textile article is a vascular graft.
5. The method of claim 1 , wherein weaving the continuous tube comprises forming a body portion and a bifurcated portion extending from the body portion.
6. The method of claim 1 , wherein forming the band includes a six-step shuttle sequence comprising:
(1) moving from face of the fabric left to face of the fabric right to weave a face of the fabric;
(2) moving from face of the fabric right to back of the fabric left to weave a back fabric right;
(3) moving from back of the fabric left to back of the fabric right to weave the back fabric right;
(4) moving from back of the fabric right to face of the fabric left to weave the face of the fabric;
(5) moving from face of the fabric left to back of the fabric right to weave a back fabric left; and
(6) moving from back of the fabric right to back of the fabric left to weave the back fabric left.
7. The method of claim 1 , wherein forming the band includes a four-step shuttle sequence comprising:
(1) moving from face of the fabric left to face of the fabric right to weave a face of the fabric;
(2) moving from face of the fabric right to face of the fabric left to weave the face of the fabric;
(3) moving from face of the fabric left to back of the fabric right to weave a back of the fabric; and
(4) moving from back of the fabric right to back of the fabric left to weave the back of the fabric.
8. The method of claim 1 , wherein the textile engineered prosthetic comprises a prosthetic trachea.
9. The method of claim 1 , wherein the band extends around ⅓ to ⅔ of an outer diameter of the continuous tube.
10. The furcated textile article of claim 1 , wherein the furcated textile article is a prosthetic trachea.
11. The method of claim 1 , wherein the at least one band of increased thickness is integral to the continuous tube.
12. The method of claim 9 , wherein the at least one band of increased thickness is integral to the continuous tube.
13. The method of claim 1 , wherein the thickness is measured in a radial direction of the continuous tube.
