Patent number: 11559327Abstract: An optical obturator apparatus includes an obturator sleeve defining a longitudinal axis and having a longitudinal bore for receiving surgical instrumentation and a transparent window mounted to the obturator sleeve and being dimensioned and configured to pass through tissue. The transparent window is mounted for movement between a first position in general alignment with the longitudinal axis of the obturator sleeve and a second position radially displaced from the longitudinal axis to thereby expose the longitudinal bore of the obturator sleeve to permit passage of the surgical instrumentation. The transparent window may include a cutting blade, or alternatively two cutting blades, adapted to penetrate tissue.Type: GrantFiled: February 25, 2020Date of Patent: January 24, 2023Assignee: Covidien LPInventors: Robert C.

Patent number: 11464614Abstract: A mesh deployment device having separate mesh deployment and actuation units is provided. A mesh deployment device includes an actuation unit and a mesh deployment unit configured to be releasably secured to the actuation unit. When the mesh deployment unit is secured to the actuation unit, a first actuation of the actuation unit moves the mesh deployment unit from an expanded condition to a collapsed condition and a second actuation of the actuation unit moves the mesh deployment unit from the collapsed condition to the expanded condition. The mesh deployment device may further include a mesh releasably secured to the mesh deployment unit. A third actuation of the actuation unit may release the mesh from the mesh deployment unit. Also provided is a kit including multiple mesh deployment units.Type: GrantFiled: June 24, 2019Date of Patent: October 11, 2022Assignee: Covidien LPInventors: William T. Kelly, Jason T.
