Patent number: 8348122Abstract: A surgical stapling device is disclosed for performing circular anastomoses. The surgical stapling device includes a handle portion, an elongated body portion and a head portion including an anvil assembly and a shell assembly. The head portion includes an anvil assembly including a tiltable anvil which will tilt automatically after the device has been fired and unapproximated. The tiltable anvil provides a reduced anvil profile to reduce trauma during removal of the device after the anastomoses procedure has been performed. The stapling device includes an approximation mechanism including a rotatable knob, a screw having a helical channel and an anvil retainer. The helical channel includes a dwell portion for providing a tactile indication to a surgeon that the anvil retainer has been advanced to a position wherein the anvil assembly can be removed from the anvil retainer.Type: GrantFiled: September 5, 2006Date of Patent: January 8, 2013Assignee: Tyco Healthcare Group LPInventors: Keith L. Milliman, Bruce K. Jankowski, Douglas J. Cuny, Kevin Sniffin, Anthony Dato, Richard D. Gresham

Patent number: 7942302Abstract: A surgical stapling device is disclosed for performing circular anastomoses. The surgical stapling device includes a handle portion, an elongated body portion and a head portion including an anvil assembly and a shell assembly. The surgical stapling device includes a knife blade possessing a lubricious coating which enhances the ability of the knife to cut through tissue and minimizes the knife sticking to tissue or other components of the surgical stapling device.Type: GrantFiled: July 11, 2008Date of Patent: May 17, 2011Assignee: Tyco Healthcare Group LPInventors: Mark S. Roby, Keith L. Milliman, Anthony Dato, Douglas J. Cuny, Anthony Gaddy, John J. Kennedy, Nicholas Maiorino, Alan Byron Cabezas

Patent number: 7546940Abstract: A surgical stapling device is disclosed for performing circular anastomoses. The surgical stapling device includes a handle portion, an elongated body portion and a head portion including an anvil assembly and a shell assembly. The anvil assembly includes a tiltable anvil which will tilt automatically after the device has been fired and unapproximated. The anvil assembly of the stapling device also includes a retainer clip positioned on the anvil head. The retainer clip includes at least one resilient arm which is positioned to engage a cutting ring during unapproximation of the stapling device.Type: GrantFiled: October 29, 2007Date of Patent: June 16, 2009Assignee: Tyco Healthcare Group LPInventors: Keith L. Milliman, Bruce K. Jankowski, Douglas J. Cuny, Kevin Sniffin, Anthony Dato, Richard D. Gresham

The surgical stapling device includes a handle portion, an elongated body portion and a head portion including an anvil assembly and a shell assembly. The head portion includes an anvil assembly including a tiltable anvil which will tilt automatically after the device has been fired and unapproximated. The tiltable anvil provides a reduced anvil profile to reduce trauma during removal of the device after the anastomoses procedure has been performed. The stapling device includes a bulbous indicator which preferably extends above a top surface of the handle assembly of the device. The indicator includes indicia to identify to a surgeon that the device has been approximated and is in a fire-ready position. Preferably, the indicator includes a cover which is formed of a magnification material to prominently display the indicia. The anvil assembly of the stapling device preferably includes a retainer clip positioned on the anvil head.Type: ApplicationFiled: October 29, 2007Publication date: March 6, 2008Inventors: Keith Milliman, Bruce Jankowski, Douglas Cuny, Kevin Sniffin, Anthony Dato, Richard Gresham
