Publication number: 20220313237Abstract: In a first aspect of the subject invention, an iris expander is provided which includes a non-metallic, unitary, multi-segmented body which is expandable from a first state to a second state. The second state defines a larger footprint than the first state with the body being defined by a plurality of segments connected by living hinges. In a further aspect, an iris expander is provided which includes a multi-segmented body that is expandable from a first state to a larger-footprint second state. At least one aperture is formed in the body with a channel extending therefrom embedded in the body such that no portion thereof is exposed externally of the body. The channel is formed to accommodate a portion of an instrument for causing adjustment of the body with avoidance of direct contact of the instrument with the tissue of the iris.Type: ApplicationFiled: June 24, 2022Publication date: October 6, 2022Inventors: Dana M. Cote, James J. Hughes

Publication number: 20220015794Abstract: A surgical knife safety device having a handle, a blade connected to the handle, and a guard carried by the handle for sliding movement between a retracted position in which the blade is exposed for use, and an extended position for covering the sharp cutting edge of the blade. In the retracted position, an enlarged guard radius is provided at the distal end of the handle to allow improved handle control and blade orientation. The enlarged guard radius is positioned to allow the user to firmly grip a large distal handle portion which is preferably molded as a single piece with the blade holder, preventing unwanted blade or handle movement due to guard mechanism tolerances.Type: ApplicationFiled: October 1, 2021Publication date: January 20, 2022Inventors: Michael J. Morawski, Dana M. Cote, Patrick T. Thrailkill, David S. Seebauer, Mohan Rajasekaran, Brian Rapp
