  • Endoscopic stapler and hernia repair mechanism
    Patent number: 5174487
    Abstract: A unique hernia repair stapler is described which allows the forming of staples to attach prosthetics to tissue, or to approximate herniated tissue. The staple is useful in endoscopic operations and may be rotatable or stationary. The stapler has a unique forming and ejecting mechanism; as well, there is the availability of a loading mechanism useful for both cartridges and magazines of staples. An improved staple shape allows for better staple alignment, especially in a multiple load device.
