Abstract:
1. A wound closure device, comprising: an elongated body having first and second sections, the sections being configured and dimensioned for insertion within tissue on opposed sides of a wound; a depth stop positioned on the elongated body to limit an insertion depth of at least a portion of the elongated body within tissue; and at least one barb extending radially outward from the elongated body, the at least one barb including a distal tip and being movable between first and second positions, wherein in the first position, the distal tip is in close cooperative alignment with the elongated body, and in the second position, the distal tip is radially offset from the elongated body, wherein the at least one barb defines an inner surface having a first portion disposed at a first orientation relative to a longitudinal axis of the elongated body and a second portion disposed at a second orientation relative to the longitudinal axis, wherein the inner surface further includes a third portion disposed at a third orientation relative to the longitudinal axis, wherein at least one of the first, second, and third portions is substantially linear, wherein the first, second, and third portions are at first, second, and third angles relative to respective longitudinal axes of the elongated body, wherein the second angle is less than each of the first and third angles, wherein the at least one barb includes a first barb being formed of a first material and a second barb being formed of a second material different than the first material, one of the first or second materials having either more flexibility or more rigidity than the other of the first and second materials.
