  • Patent number: 5403345
    Abstract: A needle suture combination and attachment method is disclosed wherein a surgical suture is attached to a surgical needle by inserting the suture tip into a tapered axial hole formed in the barrel section through the needle blunt end face and swaging the needle barrell section. The swage commences at a point away from the end of the needle end face. The needle suture attachment of the invention does not require closely corresponding suture and needle hole diameters, and advantageously achieves reliable needle-suture attachment with reduced needle inventory. Process and equipment maintenance are also reduced.
