Cook Medical, a global medical device manufacturer, has announced a new collaboration to incorporate DuPont™ Tyvek® with Renewable Attribution into its medical device packaging. Together with Nelipak® Healthcare Packaging, an Authorized Converter of Tyvek® Healthcare Packaging products, Cook is taking action to deliver more sustainable product packaging that can be seamlessly integrated into existing healthcare packaging production processes.
The project involves the use of Tyvek® with Renewable Attribution in the packaging of Cook Medical’s Compass BDS® Biliary Plastic Stent and Resonance® Metallic Ureteral Stent, helping enable more sustainable healthcare packaging by reducing product carbon footprint and dependence on fossil fuels.
“We are committed to making sustainable choices across our business,” said Barry Slowey, chief sustainability officer at Cook Medical. “By integrating Tyvek® with Renewable Attribution into our packaging, we are taking meaningful steps toward reducing our carbon footprint and promoting environmentally responsible practices. We are excited to be an early adopter of this innovative offering, and we look forward to bringing it to our customers.”
“Nelipak® has long been an Authorized Converter of Tyvek®, delivering innovative healthcare packaging solutions worldwide. By including Tyvek® with Renewable Attribution, supplied from our ISCC PLUS certified sites, in our Ecovate® sustainable product portfolio, we are taking an important step to help our medical device customers achieve their carbon footprint reduction goals,” said Pat Chambliss, CEO at Nelipak®.
DuPont™ Tyvek® with Renewable Attribution has significantly lower CO2 emissions compared to conventional Tyvek®, while retaining its trusted performance and quality. The carbon footprint reduction of Tyvek® with Renewable Attribution is enabled by the partial replacement of fossil fuel materials with certified renewable sources.
This is achieved through the mass balance approach, in accordance with the International Sustainability and Carbon Certification (ISCC PLUS) system. The use of certified bio-circular feedstock attributed to Tyvek® enables lower CO2 emissions and helps to reduce the use of fossil fuels.
“To protect our planet, we need to be innovative, passionate, and most importantly, collaborative. We are excited to work with like-minded, industry-inspiring organizations, such as Cook Medical and Nelipak®, who are helping to lead the way toward the use of more sustainable solutions in healthcare packaging,” said David Domnisch, vice president and general manager, DuPont Tyvek®.
Gayle Karch Cook, historical preservation activist and cofounder of the Cook companies alongside husband Bill Cook, passed away at 91 this morning. She is survived by her son Carl and daughter-in-law Marcy and their granddaughter, Eleanor.
“Gayle’s spirit of innovation was evident in everything she did. Whatever she was involved in, she left it better than she found it. This was true of her philosophy for the ever-growing company, her extensive efforts in renovating historically significant places, and her daily interactions with other people. That’s her inspiring legacy that we will keep striving for,” said Pete Yonkman, president of Cook Medical and Cook Group.
In 1963, Bill and Gayle Cook created a small company named Cook Incorporated that manufactured three simple medical devices used to treat patients in less invasive ways than common surgical techniques of the time. Gayle was the company’s first quality control employee, meticulously checking the devices Bill made after he finished work each night.
That small company grew into what is today Cook Group, a family of ethical and entrepreneurial companies. Cook Group includes the flagship company, Cook Medical, a global company that invents, manufactures, and delivers devices for treating conditions in almost every system of the body. Cook Group also includes companies in the life sciences, property management, resort, and service businesses.
Bill, Carl and Gayle Cook
The family planned ahead for this event, and nothing will change for employees moving forward. Carl Cook, Gayle and Bill’s son, has been CEO of Cook Group since his father’s passing in 2011. Company leadership will remain the same with Pete Yonkman as president of Cook Group and Cook Medical and Steve Ferguson as Chairman of the Board.
Gayle Karch Cook, born March 1, 1934, in Evansville, Indiana, made excellence her goal in every aspect of her life. She was salutatorian of Bosse High School when she graduated in 1952, and she earned a Bachelor of Fine Arts from Indiana University in 1956. After graduating, she began her career in advertising in Chicago. After marrying her husband, Bill, they moved to Bloomington, Indiana. There, in the spare bedroom of their apartment, they officially began the company that would later become Cook Medical. The company’s focus has always been on the patient, with a goal to make surgeries minimally invasive.
She was committed to creating a vibrant community, as she also served on the board of directors for the Star of Indiana Drum and Bugle Corps, the Bloomington Antique Mall, the Nature Conservancy, Indiana Chapter, and the board of trustees of the Indiana University Foundation.
Gayle was an avid supporter of historic preservation, and she was heavily involved in many restoration projects. She spearheaded about 70 historic preservation and economic revitalization projects, including the much-lauded West Baden Springs and French Lick resorts; Indianapolis’ Central Avenue Methodist Church; and Beck’s Mill and Cedar Farm complex in southern Indiana. The first property she restored and refurnished was the Colonel William Jones House, built in 1835. The house, which is on the National Register of Historic Places, is now a museum open to the public as a State Historic Site. Gayle restored historic sites to their original state, including the James Cochran house, the Illinois Central Freight Depot, the 8-story Graham Hotel, and more than 17 structures in the central square of Bloomington, Indiana.
In addition to her involvement in the restoration work itself, Gayle served on the boards of many restoration organizations. She was on the advisory committee of the Wylie House Museum, the Board of Governors of the Monroe County Historical Museum, the board of the Historic Landmarks Foundation of Indiana, and was an appointee of the State Historic Preservation Review Board. She was also a founder of the Monroe County History Center Annual Garage Sale which has become a staple in the Bloomington community. With every project, Gayle’s philosophy was to restore not just the site itself, but also the character and beauty of the location for present and future generations. Historic preservation wasn’t just good business; it was an investment in the community.
Gayle authored and published two books detailing her passion for Indiana’s history. The first, A Guide to Southern Indiana, was published in 1972. The other, Monroe County in Focus: Portrait of an Indiana County, was published in 1990.
A Phi Beta Kappa graduate of IU, Gayle earned a Bachelor of Arts degree in fine arts in 1956. She and her late husband were generous, far-sighted benefactors of IU’s Jacobs School of Music, School of Education, School of Medicine and Kelley School of Business, as well as supporting IU Athletics, the Wylie House Museum, the Wells Scholars program and research in the College of Arts and Sciences.

Leveraging Cook’s history of innovative medical devices in a new procedural setting
Bloomington, Ind. — Cook Medical today announced the launch of its new Interventional Magnetic
Resonance Imaging (iMRI) division, marking a significant step forward in its commitment to transforming how complex procedures and unmet clinical needs are addressed.
Unlike conventional tools repurposed for MRI use, Cook Medical is developing a portfolio of minimally invasive devices that have been purposefully engineered, over years of research and refinement, to meet the unique demands of interventional MRI environments. This approach is especially critical in pediatrics, oncology, and pediatric structural heart interventions, where precision and safety are of paramount importance. The new division marks a significant step toward transforming how clinicians diagnose, intervene, and care for patients.
The iMRI division collaborates closely with physicians, hospitals, and strategic partners to seamlessly integrate real-time magnetic resonance imaging. This empowers clinicians to visualize anatomy and instruments simultaneously, without the risks associated with ionizing radiation.
“We know that real progress happens when we listen to the people who use our products every day. The iMRI division is another example of Cook’s commitment to working alongside physicians to solve real challenges and improve lives,” said Pete Yonkman, president of Cook Medical and Cook Group. “We’re proud to support clinicians with technology that helps them do their best work for patients while advancing patient care.”
Rooted in a philosophy of prioritizing patients and physicians, Cook Medical’s iMRI division reflects the company’s longstanding commitment to meaningful, patient-centered innovation. Partnering with premier companies creating state-of-the-art imaging technology, the division aims to empower clinicians with the tools they need for improved outcomes.
Cook Medical appointed Peter Polverini as the new Vice President of the Interventional MRI division. Pete brings over 20 years of experience in advancing medical technology and fostering strong healthcare partnerships.
“I’m proud to lead a team building on years of collaboration with physicians to uncover real clinical needs. This division was born from those insights, where our devices can partner with better visualization and precision guidance to improve patient outcomes. Our mission is bold: to enable safer, more innovative, and more effective procedures through the use of interventional MRI. This is a paradigm shift in medicine, and we’re just getting started,” Polverini said.

Cook Medical has announced a €3 million investment in renewable and energy-saving technologies.
The project consists of a new 1 megawatt ground-mounted solar PV array on the grounds of the Limerick site, along with 1.2 megawatts of heat pumps to replace the existing chillers, an upgrade of electronically commutated fans, and a new energy management system.
The investment is part of the company’s carbon reduction goals, with the new technologies helping to increase the operational efficiency of the facility in Castletroy and eventually offsetting approximately 50% of carbon emissions.
This project is expected to offset up to 269 tonnes of carbon annually, and over its 25-year life cycle it will remove a total of 6,725 tonnes of carbon. Coupled with the procurement of additional green energy technologies, this will result in the removal of 60% of the carbon from the Cook Ireland site.
This project is supported by the Irish Government through IDA Ireland. Minister for Enterprise Tourism & Employment Peter Burke said, “For almost 30 years, Cook Medical has been present in Ireland and today’s announcement of a €3 million investment in renewable and energy-saving technologies is fantastic news. The combined plans are expected to offset 50% of their carbon emissions, which is in line with the Climate Action Plan to halve Ireland’s emissions by 2030. It is really encouraging to see initiatives being taken by companies focused on carbon reduction measures, sustainability and protecting the environment for future generations. I wish Cook Medical success with these plans and all their future endeavours.”
Commenting on the project, Bill Doherty, executive vice president and managing director of Cook Medical Europe, said, ‘’We are committed to making sustainable choices across our business and reducing our impact on the environment. By integrating solar panels into our operations, we’re able to enhance our efficiency while also reducing our carbon footprint.”
The company is committed to enhancing and maintaining the biodiversity of its site and will continue to safeguard the environment in its plans. In addition to reseeding native wildflowers in all areas under construction, the company will also preserve walking tracks and spaces for wildlife.
CEO of IDA Ireland Michael Lohan said: “This proposed project will position Cook’s Irish operations as an exemplar with its global network, and as a key location of subject matter expertise around energy management systems. Strongly aligned to the National Climate Action Plan’s Enterprise Pillar and IDA Ireland’s sustainability targets, we wish Cook Medical every success with this initiative which has far reaching potential.’’
Upon completion of this project, Cook Ireland will reduce its annual import of electricity by 19% and release that capacity back to the grid. A 70% reduction in the annual use of natural gas consumption is expected from the installation of the heat pumps.
A planning application has been submitted to Limerick City and County Council. If successful, construction on this project is expected to begin in due course.
Please join us as we highlight some of our leaders, learn about their experiences, and hear how they are talking about the positive changes we’re making to meet our vision of the future at Cook. Follow along for the full Meet Our Leaders series.
