Minnesota Rubber and Plastics (MRP) manufactures elastomer and thermoplastic components for medical devices.

MRP specializes in custom rubber formulations, designing and manufacturing silicone, rubber and thermoplastic components for numerous medical applications.

The company offers plastic and rubber combination parts, including sub-assemblies, allowing it to provide competent development and production efficiencies, as well as reducing development time and short and long-term costs.

Mid-sized specialty manufacturers to global leaders in the medical field utilize MRP for its advanced material expertise.

MRP’s product applications include many registered by the Food and Drug Administration (FDA) in Class 1, 2 and 3 devices. The company operates Class 10,000 International Organization of Standardization (ISO) 7 and Class 100,000 ISO 8 cleanrooms, with FDA-registered sites in China and the US.

Thermoplastic structural heart components

MRP partners with medical device companies to manufacture delivery system seals, implantable heart valve components, homeostasis valves and components, along with surgical instruments utilized in the structural heart space.

Biocompatible materials comprise the company’s thin cross-section and complex geometry of heart valve components. Molded with high-performance thermoplastics, robust and intricate devices can live within the human body for up to more than two decades.

Cardiovascular components and surgical instruments

MRP’s cardiovascular components and surgical components feature convenient designs and surface areas to enable greater control for surgeons carrying out active implantable lead placement.

The company creates the instrument’s molded parts with engineered and high-performance plastics that withstand ethylene oxide sterilization (ETO).

Molded rubber seals for insulin pumps

MRP provides medical device manufacturers with custom moulded rubber seals for insulin pumps. This precision pump is the heart of automated delivery systems, which offers continuous doses of short-acting insulin throughout the day to mimic how the human pancreas works.

The company engineers its insulin pumps, reservoirs, continuous glucose monitoring devices (CGMs) and their internal components to consistently perform flawlessly. There is no latitude for system failures, such as leaks or material breakdowns.

MRP manufactures many of its custom elastomer formulations to stringent regulations such as ISO 10993 part 5, and United States Pharmacopeia (USP) Class VI.

Medical diagnostic testing systems

MRP partners with numerous medical companies to design and manufacture a wide range of medical diagnostic testing systems.

These point-of-care diagnostic testing systems are critical to addressing immediate patient needs, such as those impacted by Covid-19.

The company’s quick and rapid response to partner with customers that have received emergency use authorization (EUA) for their devices to bring accurate and reliable testing systems online to support the global pandemic.

Surgical and orthopedic devices

MRP helps medical device companies to design and manufacture advanced surgical and orthopedic devices. Instruments include over-molded handles and surgical instruments, as well as trocar components and sub-assemblies for surgery.

MRP’s extensive portfolio also includes mixing and delivery systems seals and components.

Engineering and design services for medical device manufacturers

From the proposal, through design to prototyping to final production, MRP’s state-of-the-art design engineering services provide timely answers to complex design issues.

Leveraging tools and expertise such design for manufacturability (DFM), finite element analysis (FEA) and mold-flow analysis allows MRP to offer design alternatives quickly and precisely, while its tool development and secondary press operations are second to none.

Before committing to production, MRP’s prototyping services provide clients with production-quality sample parts for final testing.
