CAPABILITIES

Vertical Integration

Our multiple technologies supporting catheter manufacturing have been developed specifically to provide the competitive edge to leaders in the minimally invasive medical device market. Our structure is designed to provide access to each of the key technologies and processes used to build world-class catheter products, all under one roof.

Extrusion

Today's leading medical devices must be able to perform the most critical procedures with high precision, and they must do this in a minimally-invasive system. Polymer extrusions play an important role in many of these devices. For that reason, Duke Empirical prides itself on delivering the best in extrusion technology to each of our client's projects. Our Extrusion Division supplies custom extrusions to match almost any application, and does so in the shortest lead times possible. www.dukeextrusion.com

Materials

Configurations

Coiling and Braiding

Coils have a number of applications in medical devices, and Duke Empirical has the technology to provide the right coil for your application. Coiled wires are commonly used to reinforce tubing, providing excellent kink resistance without loss of flexibility. Spring loaded devices, vascular implants, and radiopaque catheters also commonly employ coil technology. Duke Empirical has built customized computer controlled coiling equipment allowing us control pitch, diameter and tension of each coil that is built. Our capabilities range from small coils (down to 0.002" I.D. with 0.001" diameter wire micro coils), to larger coils up to 0.50" I.D. and more. Examples of materials that we commonly coil include:

Duke has the capability to build multiple braid configurations, using round or flat wire in a wide range of sizes. We operate 48-carrier, 24-carrier and 16-carrier braiding machines, on which we can run up to 4 ends each. Interwoven axial fibers can be added to the braid to increase tensile strength or provide additional lumens. Examples of materials for these configurations include:

Applications

Nitinol

Nickel-Titanium alloy (Nitinol) has emerged as a material of choice for Medical device designs. The Superelastic and shape memory properties of this alloy have allowed designers to put Nitinol in places that no other metal or polymer could go. Duke Empirical has vast experience in the design and fabrication of Nitinol devices, putting this "must have" technology at your fingertips.

Surface Treatment

In order to maximize the performance of this unique alloy, Nitinol must be processed in a manner which provides a surface that is smooth and free of blemishes, oxides, or other flaws. Duke Empirical can blast, etch, and electropolish Nitinol components, maintaining extremely tight dimensional tolerances and stringent standards for surface finish. This will ensure that each Nitinol Device which Duke Empirical produces will perform as designed, every time.

Examples of applications:

Anatomical Models

Prior to clinical use of any medical device, sufficient testing must be performed to ensure that the device will perform as designed under intended conditions. For this reason, accurate anatomical models are an invaluable tool in the development and testing process. Duke Empirical employs rapid prototyping, molding, and polymer technologies to produce models of human anatomy. These models may be based upon true human anatomy (for example from patient CT scan data) or shapes which are custom designed to simulate clinical use.

Hydrophilic Coating

Today's interventional devices must have superior control and performance in order to meet the demands of physicians who use them. Surface lubricity is a key performance feature in accessing difficult vasculature. Duke Empirical offers hydrophilic coating of catheters and interventional devices to enhance trackability through tortuous anatomy and tight lumens. Hydrophilic coating adds a notable slick surface quality to a device. All of the coating materials applied to our products have a history of use and approval in interventional devices.

Machining

Our precision machining center brings the finest CNC technology to your project, delivering the closest tolerance components in the fastest possible lead times. Employing ultra-high speed tools and multi-axis programmability, our engineers can fabricate intricate components from Steel, Aluminum, Delrin, ABS, PEEK, PTFE, and more. Custom tools and precision components that normally take weeks to design and fabricate can be conceived, produced, and tested in a fraction of the time. Our CNC machine includes:

Rapid Prototyping

Duke Empirical employs state of the art rapid prototype technology to bring our clients' products to life. Using both Fused Deposition Modeling (FDM) and Direct Light Projection (DLP) processes, our designers are able to create high-resolution, functional models in a variety of materials. These models are exceptionally useful for a number of applications, including:

Features of our rapid-prototype components include:

Catheter Processing Tools

Utilizing our rapid prototyping and machining capabilities Duke Empirical provides to its customers a broad array of custom process tools. Examples include:

Whether you are developing catheters, delivery systems, or surgical tools, the user interface must look, feel, and function flawlessly. Duke Empirical's rapid design and prototype capabilities ensure that you will achieve the optimum design in the shortest time possible.

Pad Printing

When a medical device requires that finishing touch, Duke Empirical can provide custom printing on the surface of most materials which we process. Pad Printing is a proven method which provides consistent, repeatable results. Duke Empirical utilizes biocompatible ink and validated processes to ensure that your finished device is printed with a clear and attractive artwork matching your custom design. Some examples of applications for our pad printing technology include:
