Abstract
A medical device includes a surgical needle attached to a hollow tubular suture. The suture is constructed of macroporous hollow tubular wall that facilitates and allows tissue integration into the suture core subsequent to introduction to the body, thereby preventing suture pull-through and improving biocompatibility.
Claims20
A medical device comprising:
- a surgical needle;
- and
- an elongated suture having a first end attached to the surgical needle and a second end located away from the surgical needle, the elongated suture including a tubular wall, a hollow core inside of the tubular wall, and a plurality or pores extending through the tubular wall, at least some of the pores having a pore size that is greater than or equal to approximately 500 microns such that the pores are adapted to facilitate tissue integration through the tubular wall of the suture when introduced into a body.
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 a tubular suture;
- threading the tubular suture through the soft tissue, wherein the tubular suture comprises a tubular wall, a hollow core inside of the tubular wall, and a plurality of pores extending through the tubular wall, at least some of the pores having a pore size that is greater than or equal to approximately 500 microns such that the tubular suture is adapted to accommodate the soft tissue growing through the tubular mesh wall and into the hollow core, thereby integrating with the suture.
