Patent number: 10421569Abstract: The present invention relates generally to methods of sterilizing elastomeric articles in a manner that prevents and/or reduces degradation to the articles, particularly degradation that may be caused and/or accelerated by sterilization techniques such as gamma irradiation, x-ray irradiation, and electron-beam processing. The methods include packaging the elastomeric articles in order to improve their resistance to degradation. In certain aspects of the invention, packaged elastomeric articles, optionally containing one or more antidegradants, such as antioxidant and/or antiozonant compounds, are also provided. The methods of providing degradation-resistant elastomeric articles in accordance with the present invention may also be used to reduce the occurrence of cracking and discoloration in elastomeric articles, regardless of whether they are subjected to sterilization.Type: GrantFiled: June 3, 2016Date of Patent: September 24, 2019Assignee: Allegiance CorporationInventors: Seong Fong Chen, Wei Cheong Wong

Publication number: 20180110579Abstract: An integrated tray and wrap system for supplying components used in medical procedures is provided and a method of manufacturing the tray while filling and sealing in one continuous process. The trays can be formed on a process line, such as by a thermo-form-fill-seal technique, and once the cavity of the tray is formed, the desired medical components can be loaded into the tray cavity as the formed trays are advanced down the process line. After the components are loaded, a pre-folded drape or non-woven sheet can be affixed to an inner ledge of the tray along an inner fenestration of the drape or sheet, thus attaching the drape or sheet to the tray. Once the drape has been attached, the tray continues to advance along the process line to receive a cover film that can be heat-sealed to the outer rim of the tray.Type: ApplicationFiled: October 25, 2017Publication date: April 26, 2018Applicant: Allegiance CorporationInventors: VARSHA KALYANKAR, ANDREW M ROLSMA, ELIEZER APONTE, NICHOLAS GUS FOTIS, DANNY W PENNY
