Adopt standardized protocols and advanced technologies to achieve consistent throughput. For instance, Millstone Medical employs automated tray-sealing equipment to reduce manual handling and speed up production. Regular audits can also identify and address inefficiencies.

The Advantages of Custom Kitting in Complex Medical Device Assembly

Custom kitting is essential for efficiently assembling, packaging, and distributing complex medical devices. OEMs can streamline operations, improve surgical workflows, and enhance sterility by organizing components into single-use or reusable kits. Here are three key benefits of custom kitting in medical device assembly.

1. Simplifying Surgical Workflows

In a fast-paced surgical environment, every second counts. Custom kitting streamlines workflows by providing pre-assembled kits containing all necessary components for specific procedures. This approach eliminates the need to open multiple packages or search for individual items, giving surgical teams a single sterile kit ready for use.

Why It Matters:  

Disorganized supplies can disrupt procedures, increase patient risk, and strain resources. Pre-assembled kits save time and reduce cognitive load, enabling healthcare professionals to focus on patient care.

Solution:  

In cardiovascular surgeries, custom kits from Millstone Medical include pre-packaged stents, catheters, and guidewires for efficiency and reduced preparation time. Collaborating with OEMs, we design procedure-specific kits that streamline workflows while maintaining strict sterility standards in our ISO 7 cleanroom facilities. Standardized kits simplify staff training and reduce setup errors, improving surgical outcomes.

2. Enhancing Efficiency in Cleanroom Assembly

Efficiency is vital in assembling complex medical device kits. Traditional methods often lead to difficulty managing numerous stock-keeping units (SKUs), tracking components, and human errors. Custom kitting addresses these issues by organizing related items into easy-to-manage kits, reducing complexity.

Why It Matters:

Handling many individual parts can overwhelm cleanroom staff, slow production, and increase errors. Pre-kitted components streamline operations, cut assembly time, and simplify inventory.

Solution:

OEMs can reduce the number of SKUs for tracking and storage by consolidating related components into single kits. This approach minimizes confusion, shortens lead times, and boosts cleanroom efficiency. Millstone Medical utilizes advanced tracking systems and custom packaging to optimize assembly, applying lean manufacturing principles to ensure consistent output and minimize disruptions.

3. Improving Sterility Assurance

Maintaining sterility is crucial in medical device manufacturing, as contaminated devices can compromise patient safety and lead to costly recalls. Custom kitting enhances sterility by minimizing component handling and packaging.

Why It Matters:  

Each interaction during assembly increases the risk of contamination. Custom kits centralize packaging in a controlled cleanroom environment, reducing these risks.

Solution:  

ISO 14644 standards require strict environmental controls in cleanrooms to prevent contamination during assembly and packaging. Millstone Medical’s cleanroom facilities employ advanced technology to ensure compliance through custom kitting.
