Buttress for cardiac valve reconstruction
First Claim
1. A buttress for reconstructing a cardiac valve having cusps, the buttress comprising:
- two superimposed layers of a fabric forming an elongate member, the fabric partially-annularly fitting against a base of the cusps, the fabric being longitudinally extendable to 105-150% of a non-extended length of the elongate member; and
,longitudinally extending seams for fastening the layers together, said seams having inwardly extending opposing selvedges.

Abstract
A buttress for cardiac valve reconstruction comprises an elongate member formed from two superimposed layers of a fabric. The layers are fastened together by longitudinally extending seams having inwardly extending opposing selvedges. The elongate member fits part-annularly against the base of the cusps of the cardiac valve. The fabric is longitudinally extendable to 105-150% of its non-extended length. An apparatus for cardiac valve reconstruction comprises a holder, including a buttress receiving area; and a buttress comprising a part-annularly shaped elongate member formed from a fabric. The buttress is removably mounted onto the buttress receiving area of the holder in an extended condition, the extended condition being 105-150% of the non-extended length of the elongate member. The buttress and apparatus can be used in the reconstruction of mitral and tricuspid cardiac valves.

16. An apparatus for cardiac valve reconstruction, the apparatus comprising:
-
a holder including a buttress receiving area having a partially-annular configuration; a buttress comprising an elongate member and being of a fabric, the fabric being longitudinally extendable to an extended condition being 105-150% of a non-extended length of the elongate member; and
,mounting means for removably mounting the buttress on the buttress receiving area in the extended condition. - View Dependent Claims (17, 18, 19, 20, 21, 22, 23, 24, 25)

26. A method for cardiac valve reconstruction, the cardiac valve having cusps, comprising the steps of:
-
reversibly mounting a buttress onto a holder to form an apparatus for cardiac valve reconstruction, the buttress comprising an elongate member of a fabric, the fabric being longitudinally extended to 105-150% of a non-extended length of the elongate member; fixing the buttress to a base of the cusps; and detaching the buttress from the holder thereby allowing the buttress to contract towards the non-extended length. - View Dependent Claims (27, 28)
