Single continuous piece prosthetic tubular aortic conduit and method for manufacturing the same
First Claim
1. An aortic prosthetic comprising:
- a conduit having a first portion, a skirt portion, and a third portion, all continuously woven together, wherein the skirt portion has a larger diameter than the first portion or the third portion, and a tightness of rows of yarn in the skirt portion is different than a tightness of rows of yarn in the first and the third portion.

Abstract
A prosthetic aortic conduit for replacing a root portion of an aorta is provided. The conduit comprises a continuous tubular conduit along a substantially common axis. A portion of the tubular conduit does not substantially deform in a longitudinal direction and has resilient means which allow said another portion of the conduit to be expandable in a lateral direction. The portion that is able to deform laterally mimics the function of the sinuses of Valsalva. The method of manufacturing such a conduit comprises the steps of having a continuous weave of rows of yarn or the equivalent with a change in tightness of the rows so that in some portion of the conduit it is expandable in the lateral direction and in some portion of the conduit it is expandable in the longitudinal direction.

5. An aortic prosthetic comprising:
-
rows of yarn forming a continuously woven conduit, wherein the continuously woven conduit comprises; a first portion comprising a first diameter; and a skirt portion comprising a second diameter larger than the first diameter, wherein spacing between a plurality of the rows of yarn are closer in the skirt portion than spacing between the plurality of the rows of yarn in the first portion. - View Dependent Claims (6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18)

20. A method of manufacturing a prosthetic aortic conduit having first and second ends, and rows of yarns of varying spacing, the method comprises the following steps:
-
weaving a first conduit suitable for use in heart surgery, said first conduit having a longitudinal axis; continuing weaving of the first conduit to form a skirt conduit suitable for use in heart surgery, wherein the skirt conduit has a larger diameter than that of the first conduit, and a spacing of the rows of yarn used to weave the prosthetic aortic conduit is different in the skirt conduit than the first conduit; and continuing the weave of the skirt conduit to form a third conduit. - View Dependent Claims (21, 22, 23, 24)
