ICU Medical Brand Guidelines: The San Clemente Clave Maker That Bought Smiths Medical

A physician’s locking IV connector in Orange County.

ICU Medical began in 1984 in Southern California. English Wikipedia says it was founded by George “Doc” Lopez, a physician, who developed a product called the ClickLock to secure intravenous lines; his own Wikipedia entry describes him as a board-certified internist and the ClickLock as a protected needle in a locking housing for IV systems. The company is based in San Clemente, in Orange County, California, which its press releases still give as their dateline.

The ClickLock was followed by the Clave, a needlefree connector for IV lines, and later by the Neutron catheter device, English Wikipedia says. For years the Clave carried the company. In 2002 Lopez told the Orange County Business Journal that “diversification doesn’t help a company.” By July 2009 the same paper reported that ICU was “finally shaking it up,” making custom IV sets and adding products to lessen its reliance on one large customer, Hospira, which had been a key customer for some fifteen years, going back to Hospira’s days as part of Abbott Laboratories. Lopez described his approach as a search for “empty markets.”

One of those markets was oncology. English Wikipedia dates ICU’s first oncology products to 2006, while the Orange County Business Journal reported in 2011 that it began selling them in 2008. Among them was the ChemoClave, a closed system transfer device for preparing and giving hazardous drugs; Lopez was its lead inventor, Wikipedia says, and in 2012 ICU added the Diana compounding system. Lopez retired as chief executive and chairman in 2014 and stayed on the board, according to Wikipedia. The company’s releases from 2021 onwards name Vivek Jain as chief executive.

Hospira, then Smiths Medical.

ICU Medical grew by buying businesses from larger companies. In July 2009 it bought a critical care product line from Hospira, the Orange County Business Journal reported; English Wikipedia says this came after four years in which ICU had made Hospira’s critical care products under contract, and that it brought manufacturing space in Salt Lake City, Utah. In 2010 ICU opened a plant in Slovakia, the same paper reported in 2011. In 2015 it bought Excelsior Medical, maker of the SwabCap disinfecting cap, and in February 2017 it bought Hospira Infusion Systems from Pfizer, Wikipedia says. After that deal, the Orange County Business Journal noted in 2022, ICU’s 2020 annual report described it as “the only company to focus exclusively on IV therapy across the continuum of care.”

The largest step came next. On 8 September 2021 ICU Medical and Smiths Group of London announced that ICU would buy the Smiths Medical division, in a deal the two companies called superior to a sale Smiths had already agreed with a buyer named Trulli Bidco; Smiths would also take a stake of about ten per cent in ICU. ICU said on 6 January 2022 that the purchase was complete, adding syringe and ambulatory infusion devices, vascular access and “vital care” products. The Orange County Business Journal called it ICU’s largest-ever acquisition and reported that the two sides had begun talks in 2018.

The product names on ICU’s website today reflect that history. Alongside the Clave connectors and the ChemoClave and ChemoLock transfer devices, it lists the Plum, CADD and Medfusion pump families and the Portex airway range. In April 2025 the company announced FDA 510(k) clearance for its Plum Solo and Plum Duo pumps, which it presents as a new category it calls precision IV pumps.

Bedside and ward.

Hospital device makers sell to clinicians, purchasing teams and hospital engineers rather than to shoppers, and their brands are built for that audience. Their catalogues and websites tend to show the equipment where it is used: infusion pumps on poles beside a bed, dialysis machines lined up in a treatment room, monitors and consoles in intensive care.

Much of the product is small and disposable, so the pictures often come close. Gloved hands hold a catheter, a cannula or an infusion set; blood tubing is coiled for a dialysis session; a dialyzer or a single-use endoscope is photographed on plain white so that every connector and label can be read. Product names usually lean on model numbers and technical terms rather than on lifestyle words.

People appear too, usually in uniform: nurses and doctors at the bedside, technicians at a workbench, trainers at a company teaching centre. Several makers in this group run their own training facilities for clinicians, and they present them as part of what they sell alongside the devices.

The trade meets at congresses and fairs. Medica in Düsseldorf gathers hospital suppliers from around the world each autumn; ASN Kidney Week, the American Society of Nephrology’s annual meeting, draws dialysis makers; and Digestive Disease Week brings together gastroenterologists and endoscopy suppliers. Stands, booth graphics and congress brochures are where many of these brands are seen at their largest, and this guide sets out what can be checked about each company: who founded it, who owns it, and where it says its products are made.

A San Clemente name on IV therapy.

ICU Medical has also drawn regulatory attention. On 4 April 2025 the US Food and Drug Administration sent the company a warning letter after inspecting the former Smiths Medical site in Minneapolis in July and August 2024. The letter said the Medfusion Model 4000 syringe pump and the CADD-Solis VIP ambulatory pump had been changed without the premarket submissions the agency requires. MedTech Dive reported that the changes were fixes made after a Class I recall over fluid delivery, false alarms and interrupted therapy, and that the letter followed a series of recalls since the Smiths Medical purchase.

Manufacturing is spread widely. Besides Salt Lake City and Slovakia, the Smiths Medical business brought manufacturing operations in the United States, the United Kingdom, Mexico and Italy, the Orange County Business Journal reported in 2022. In May 2025 ICU and Otsuka Pharmaceutical Factory of Tokushima, Japan, formed Otsuka ICU Medical LLC, a joint venture for IV solutions in North America that combines ICU’s production in Austin, Texas, with Otsuka’s sixteen IV-solution sites in Asia, the companies said. In September 2025 ICU announced new FDA-cleared labelling for the Clave connector family, which it says clinicians have used for more than thirty years.

The company’s description of itself has changed with its size. Its 2025 releases call it “a worldwide leader in the development, manufacture and sale of innovative medical devices” and “a global medical technology company specializing in IV therapy and critical care”; these are its own words. It is listed on Nasdaq and still gives San Clemente as its home.

For a design guide, ICU Medical shows how a company built on one small connector can take in older names — Hospira’s infusion business, Smiths Medical’s Portex and CADD — and keep them as product brands under its own. Compare Smiths Medical, the division it bought, and Baxter, another American hospital-products company. For this guide we use a deep clinical blue, a teal and a pale saline grey with a sans, an unofficial interpretation; no product or logo is reproduced.
