Knit Hemostatic Bandage

A knit hemostatic bandage comprising:

• a first continuous fiber having a Young's modulus of elasticity of between 1 GPa and 30 Gpa;
• a second continuous fiber having a Young's modulus of elasticity of between 70 GPa and 75 GPa,
• wherein the first continuous fiber and the second continuous fiber are arranged to form stitches, each stitch comprising a loop of the first continuous fiber and a loop of the second continuous fiber,
• wherein adjacent stitches alternate between (i) a first configuration in which the loop of the first continuous fiber is disposed toward a first face of the knit hemostatic bandage and the loop of the second continuous fiber is disposed toward a second face of the knit hemostatic bandage, the second face opposite the first face, and (ii) a second configuration in which the loop of the first continuous fiber is disposed toward the second face of the knit hemostatic bandage and the loop of the second continuous fiber is disposed toward the first face of the knit hemostatic bandage,
• wherein the stiches are configured such that relative motion of the loops of the first continuous fiber and the loops of second continuous fiber occurs responsive to deformation of the knit hemostatic bandage, and
• wherein an overall Young's modulus of the knit hemostatic bandage is less than the Young's modulus of the first continuous fiber and less than the Young's modulus of the second continuous fiber.

A method of making a knit hemostatic bandage, the method comprising:

• knitting stitches of a first continuous fiber and a second continuous fiber, wherein the first continuous fiber has a Young's modulus of elasticity of between 1 GPa and 30 GPa and the second continuous fiber has a Young's modulus of elasticity of between 70 GPa and 75 GPa, wherein the knitting includes:
• knitting the first continuous fiber and the second continuous fiber such that each stitch comprises a loop of the first continuous fiber and a loop of the second continuous fiber, and such that adjacent stitches alternate between (i) a first configuration in which the loop of the first continuous fiber is disposed toward a first face of the knit hemostatic bandage and the loop of the second continuous fiber is disposed toward a second face of the knit hemostatic bandage, the second face opposite the first face, and (ii) a second configuration in which the loop of the first continuous fiber is disposed toward the second face of the knit hemostatic bandage and the loop of the second continuous fiber is disposed toward the first face of the knit hemostatic bandage;
• wherein the stitches are configured such that relative motion of the loops of the first continuous fiber and the loops of second continuous fiber occurs responsive to deformation of the knit hemostatic bandage, and
• wherein an overall Young's modulus of the knit hemostatic bandage is less than the Young's modulus of the first continuous fiber and less than the Young's modulus of the second continuous fiber.
