Patent number: 11123105Abstract: A visual insufflation obturator is provided. The obturator includes seals, valves, screens and/or various other tip features to eliminate the ingress of fluids, matter and/or gas that can disrupt the visual field of the laparoscope disposed within the obturator. The obturator provides additional features such as lens and anti-fog features to further increase visibility of the scope, efficiently insufflate the patient and ultimately provide an access channel into the insufflated abdomen once the visual insufflation obturator is removed.Type: GrantFiled: November 21, 2018Date of Patent: September 21, 2021Assignee: Applied Medical Resources CorporationInventors: Scott V. Taylor, Paul W. Balschweit, Jeremy J. Albrecht, Gary M. Johnson, Said S. Hilal, Zoran Falkenstein

Patent number: 11051812Abstract: A surgical stapler includes a jaw assembly at a distal end connected to a handle assembly that is configured to control the stapler and actuate the deployment of staples. The surgical stapler successfully eliminates intermediate caming portions commonly known as pushers that are located between the staples and a translating slider. The staples are located in pockets at an angle such that the base of the staple is parallel to an angled caming surface of the slider. The translating slider comes into direct contact with staples during deployment as the slider moves through each staple pocket where staples are partially supported by recesses along the slider pathway. The staples are deployed at an angle against the anvil surface. Because there are no pushers, a great deal of space is saved resulting in a much smaller diameter surgical stapler that is particularly suitable for laparoscopic stapling applications.Type: GrantFiled: December 19, 2017Date of Patent: July 6, 2021Assignee: Applied Medical Resources CorporationInventors: Timothy M. Hopkins, Donald L. Gadberry, Matthew M. Becerra, Babak Jasemian, Gary M. Johnson, Steven E. Decker

Patent number: 10918814Abstract: An insufflating surgical instrument adapted for movement across an abdominal wall to insufflate an abdominal region of a patient is disclosed. The instrument comprises a shaft having an insufflation channel extending between a proximal end and a distal end, the insufflation channel being adapted for connection to a source of fluid under pressure at the proximal end. A tip is at the distal end and a vent hole is formed in the tip being in connection with the insufflation channel and adapted to expel fluid under pressure to insufflate the abdominal region. The tip is formed of a transparent material to facilitate visualization of the abdominal wall and region. The shaft includes a lumen extending along the axis between the proximal end and the distal end to enable insertion of a laparoscope. The lumen and insufflation channel may be formed as separate channels or as one shared channel.Type: GrantFiled: March 4, 2019Date of Patent: February 16, 2021Assignee: Applied Medical Resources CorporationInventors: Jeremy J.

Patent number: 10888326Abstract: Jaw assemblies for a surgical stapler are provided. The jaw assemblies comprise a first jaw having a first clamping surface and a plurality of staples disposed therein and second jaw assembly having a second clamping surface. The jaw assemblies can be actuated from a closed configuration in which the first clamping surface contacts or is adjacent to the second clamping surface to an open configuration in which the second jaw is pivoted away from the first jaw to a stapling position in which the second clamping surface is parallel to the first clamping surface and spaced apart from the first clamping surface. A pivoting link or sliding pivot joint can couple the second jaw to the first jaw to facilitate motion between the closed position, the open position, and the stapling position.Type: GrantFiled: October 19, 2017Date of Patent: January 12, 2021Assignee: Applied Medical Resources CorporationInventors: Jonathan Covach, Matthew M.
