Abstract
Surgical suture assemblies, and methods of their use, are disclosed having configurations suitable for closure of biological tissue, including the bony tissue of the sternum. The surgical suture assemblies described or contemplated herein have physical characteristics that help to mitigate undesirable issues, such as bleeding.
Claims22
An assembly, comprising:
- a needle portion having a maximum diameter, a tapered distal portion ending in a distal tip, and a proximal end;
- and
- a wire portion coupled to the proximal end of the needle portion, the wire portion including a wire, the wire having a distal end, a proximal end, a transition portion, a distal portion extending from the distal end of the wire to a distal end of the transition portion, and a proximal portion extending from a proximal end of the transition portion to the proximal end of the wire, a first diameter at a first location along the distal portion of the wire and a second diameter at a second location along the proximal portion of the wire, the second diameter being greater than the first diameter,
- the wire formed from metal, the wire having a smooth outer surface and a solid cross section extending along the entire length of the wire, the solid cross section of the wire being a solid circular cross section along the distal and proximal portions of the wire, and
- an overall diameter of the wire portion at the second location of the wire being greater than both an overall diameter of the wire portion at the first location of the wire and the maximum diameter of the needle portion.

A surgical suture assembly, comprising:
- a needle portion having a maximum diameter;
- and
- a wire portion coupled to the needle portion, the wire portion including a wire, the wire having a first end, a second end, a transition portion, a first portion extending from the first end of the wire to a distal end of the transition portion and a second portion extending from a proximal end of the transition portion to the second end of the wire, a first location along the first wire portion having a first diameter and a second location along the second wire portion having a second diameter, the second diameter being greater than the first diameter, the transition portion located between the first location and the second location along the wire,
- the wire formed from a single material, the wire having a smooth outer surface and a solid cross section extending at least from the first location, through the transition portion, to the second location, the solid cross section being a solid circular cross section at the first location and the second location, and
- an overall diameter of the wire portion at the second location of the wire being greater than both an overall diameter of the wire portion at the first location of the wire and the maximum diameter of the needle portion.

- the wire formed from metal, the wire having a smooth outer surface and a solid cross section extending along the entire length of the wire, the solid cross section of the wire being a solid circular cross section at least at a location where the distal end of the transition portion meets the distal portion of the wire, and
- an overall diameter of the wire portion at the second location of the wire being greater than both an overall diameter of the wire portion at the first location of the wire and the maximum diameter of the needle portion.
