About V-Muller
Specialty Armamentarium

More than 100 years ago in Chicago, Vinzenz Mueller started a small storefront business to provide physicians and surgeons with fine instruments and exceptional customer service.

Mr. Mueller was guided by the principle that keeping all promises made to his customers even if at a cost was essential to the long-term success of his business. Since then, V. Mueller has set the standard for service in the industry, which is still part our company culture today.

The tradition of making fine surgical instruments continued when William Merz started as an instrument apprentice for Mr. Mueller in 1928.

Driven by the idea of improving the lives of patients, Mr. Merz used his specialized knowledge and skills to translate surgeon problems or ideas into more efficient surgical instruments. His passion for advancing quality surgical instrumentation helped build his reputation as one the best-known instrument makers in the world.

We are thankful for the thousands of innovative surgeons, operating room and sterile processing professionals, and other healthcare personnel who have collaborated with us to develop our high-quality, innovative new products. Today, the V. Mueller and Snowden-Pencer instrument lines include more than 25,000 instruments used in hospitals across the globe.

We are also proud of our craftsmen and supporting staff who continue our tradition of providing high-quality surgical instrumentation and customer service for customers everywhere.

We dedicate this armamentarium to our customers. We value your loyalty, support and ideas that have ensured our successful partnership throughout the years.

Mindful of our heritage and responsibility to work toward ever-higher standards of excellence, we enjoy listening to and serving your needs in surgery.

Our standards of quality originated with our founder, Vinzenz Mueller.

In 1893, he brought the knowledge of German instrument craftsmanship to the United States and established a tradition that has carried through to today.

His protege, William Merz, established the V. Mueller name as one synonymous with innovation and collaboration. In 1951, Leonard Snowden and George Pencer introduced the revolutionary tungsten carbide insert to the jaws of surgical instruments.

CareFusion is now proud to offer the Snowden-Pencer family of products to our customers.

These men dedicated their lives to improving surgical instruments and patient care.

Our customers have always expected high quality and first-rate technology from our surgical instruments, which are promises CareFusion continues to deliver on today.


At CareFusion, our commitment to quality stems from our ability to understand customer needs and exceed industry expectations. Our sales force has more than 125 knowledgeable V. Mueller representatives, some with more than 30 years of experience. In addition, our V. Mueller and Snowden-Pencer customer support team ensures accurate order processing and technical support. We are all here to help. Once our products are in your hands, our service quality does not stop. We offer many opportunities for continuing education. In addition, all of our surgical instruments are backed by a lifetime warranty against defects in materials and workmanship.


CareFusion prides itself on the quality craftsmanship of our V. Mueller and Snowden-Pencer surgical instruments. Though technology has progressed over the years, all of our instruments maintain a handcrafted component. We know that small details make a real difference in the hands of surgeons.

That is why we consider our surgical instruments an art form and attention to detail critical. This mindset and pride ensure our surgical instruments are among the highest in quality.

Our entire manufacturing process reflects our dedicated specializations through:

• Training instrument craftsmen by apprenticeships

• Inspecting instruments for quality throughout manufacturing

• Placing instruments under several stages of heat treatment, followed by quick cooling to achieve the proper hardness and strength

• Deep cleaning instruments, and preventing their corrosion by passivation

We have also proudly maintained a manufacturing presence in the United States for more than 115 years. With state-of the art manufacturing and operational facilities in St. Louis, MO; Tucker, GA; Cleveland, OH; and Tuttlingen, Germany, our quality instruments are manufactured under consistent standards by highly skilled individuals.
