Abstract
A medical device includes a surgical needle attached to a mesh suture having anti-roping elements. The suture is constructed of a flat macroporous mesh wall that facilitates and allows tissue integration subsequent to introduction to the body, thereby preventing suture pull-through and improving biocompatibility. Advantageously, the anti-roping elements serve to maintain the desired construct of the flat mesh wall when undergoing axial tensile loads by resisting elongation and loss of outer mesh wall macroporosity.
Claims20
A medical device comprising:
- a surgical needle;
- an elongated mesh suture having a first end attached to the surgical needle and a second end located away from the surgical needle, the elongated mesh suture including a flat wall and a plurality of pores extending through the flat wall;
- and
- one or more anti-roping elements fixed to the mesh wall, the anti-roping elements resisting elongation of the elongated suture when a tensile load is applied along an axial direction between the first and second ends of the elongated suture,
- the flat wall having a length dimension extending substantially entirely from the first end to the second end of the elongated mesh suture, the flat wall having a cross-sectional rectangular profile with a substantially uniform width dimension and a substantially uniform thickness dimension along the entire length dimension, the width dimension being greater than the thickness dimension and the width dimension being between approximately 1 mm and approximately 1 cm,
- at least some of the pores having a pore size that is greater than or equal to approximately 200 microns such that the pores are adapted to facilitate tissue integration through the flat wall when the elongated mesh suture is introduced into a body.
The medical device of 14, wherein the proximal end of the surgical needle includes a rectangular cross-sectional profile.
A method of re-apposing soft tissue, the method comprising:
- piercing a portion of the soft tissue with a surgical needle attached to a first end of an elongated mesh suture;
- threading the elongated mesh suture through the soft tissue, wherein the elongated suture includes the first end attached to the surgical needle and a second end located away from the surgical needle, the elongated mesh suture including a flat wall and a plurality of pores extending through the flat wall, and one or more anti-roping elements fixed to the flat wall, the anti-roping elements resisting elongation of the elongated mesh suture while threading the mesh suture through the soft tissue,
- the flat wall having a length dimension extending substantially entirely from the first end to the second end of the elongated mesh suture, the flat wall having a cross-sectional rectangular profile with a substantially uniform width dimension and a substantially uniform thickness dimension along the entire length dimension, the width dimension being greater than the thickness dimension and the width dimension being between approximately 1 mm and approximately 1 cm, at least some of the pores having a pore size that is greater than or equal to approximately 200 microns such that the pores are adapted to accommodate the soft tissue growing through the flat mesh wall, thereby integrating with the elongated mesh suture.
