Publication number: 20210177462Abstract: A device and method for application of a cervical cerclage suture to a patient's cervix is disclosed. The device includes a housing having a first end and a second end spaced from the first end and defining an internal passageway. The device includes a retractable claw having a shaft slidable in the passageway and comprising a plurality of spaced flexible fingers that hold and release the cerclage suture. Each flexible finger may have a through-hole for receiving the cerclage suture, and may have a radial slit in communication with the through-hole and through which the cerclage suture is releasable from each finger. The claw is movable in the housing between a retracted state and an extended state relative to the housing. The shaft is operatively connected to the claw to move the claw axially relative to the housing.Type: ApplicationFiled: December 12, 2020Publication date: June 17, 2021Inventors: Alexis C. Gimovsky, Felek Jachimowicz, Ehsan Hajiesmaili, Jordon T. Levine, Gregory A. Walters

Patent number: 10752549Abstract: The present invention relates to modification of hydratable cement and cementitious materials, such as mortar cement and masonry or ready-mix concrete using ketone alcohol oil waste (“KAOW”) material, obtained as an alkali-soluble liquor waste byproduct at a certain stage in the commercial production of cyclohexanol and cyclohexanone. Preferred applications for KAOW are in chemical admixture formulations whereby KAOW is used to substitute for a portion of a cement dispersant such as sodium lignosulfonate, sodium gluconate, or other conventional dispersant. Another preferred use is in mortar cement and masonry concrete units such as blocks, pavers, curbstones, and other concrete masonry units wherein air void systems advantageously foster freeze-thaw durability.Type: GrantFiled: February 27, 2015Date of Patent: August 25, 2020Inventors: Shuqiang Zhang, Hua Zhong, Wee Fuk Lai, Felek Jachimowicz, Byong-wa Chun, Yin-Zar Hnin
