  • Patent number: 6174220
    Abstract: A method of manufacturing blunt tip surgical needles. Taper point needles having conventional piercing tips are placed into a vessel containing a grinding media. The needles are maintained in the vessel for a sufficient amount of time to convert the piercing point into a blunt. Additionally, the needles may be separated from the grinding media using a rotating magnetic drum such that the needles remain engaged with the magnetic drum while the grinding media is directed away to a collection tray. Needles are later removed from the magnetic drum.

  • Patent number: 5219358
    Abstract: Surgical needles are fabricated from a shape memory alloy. The alloy has a low temperature state, in which the needle is formable into an elongated shape to pass through an elongated tube, and a high temperature state, in which the needle forms an arc. The needle is particularly adapted for use in endoscopic surgery. A needle that has a remembered curved shape is straightened and passed to a surgical site through a cannula. It is then returned to its curved shape by heating it at the surgical site. After use, it is withdrawn through the cannula.
