Prosthesis comprising a three-dimensional and openworked knit
First Claim
1. A prosthesis comprising at least one openworked three-dimensional knit comprising two opposite faces, a front face and a rear face, each front and rear face being formed with one or several laps of yarns defining pores on said front and rear faces, said front face being bound to said rear face by connecting yarns defining a spacer, wherein the connecting yarns are distributed so that said connecting yarns define a crisscrossing set of yarns crossing each other at the spacer, without obstructing the pores of the two opposite faces, wherein said connecting yarns are yarns from at least one lap from the laps forming said opposite faces.

Abstract
The present invention relates to a prosthesis (100) comprising an openworked three-dimensional knit (101) comprising a front face and a rear face, each face being formed with one or more laps of yarns defining pores on said face, the front face being bound to the rear face by connecting yarns defining a spacer, characterized in that the connecting yarns are distributed so that they define an entanglement of yarns crossing each other at the spacer, without obstructing the pores of the front and rear faces.

20. A prosthesis comprising at least one openworked three-dimensional knit comprising a front face and a rear face, each face being formed with one or more laps of yarns defining pores on said face, one face being bound to the opposite face by connecting yarns defining a spacer, the connecting yarns being distributed so that the connecting yarns define a crisscrossing set of yarns crossing each other at the spacer, without obstructing the pores of the two opposite faces, said knit being obtainable by knitting on a knitting machine of the warp or Rachel type comprising two opposite beds, each respectively with m and m′
- needles, the needles m of one bed facing the needles m′
of the opposite bed, the connecting yarns being distributed over at least one guide bar BE1, said bar BE1 bar having at least one lateral movement in one direction from one needle mi of one of the two beds to a needle (mi′
+x) of the opposite bed, wherein x ranges from 2 to 5, and a lateral movement in the opposite direction from a needle mj of one of the two beds to a needle (mj−
x′
) of the opposite bed, wherein x′
ranges from 2 to 5. - View Dependent Claims (21, 22, 23)
