General Medical

Plastics are used in a variety of disposable medical products and single use devices. While off-the-shelf plastics have been used in many of these applications, demand continues to grow for custom polymer blends, stabilized polymers and pre-colored polymers for wound care, sterilization trays, packaging and more. 

Foster has added state-of-the-art extrusion compounding capacity for custom compounding polymers used in high volume medical applications.   Our latest twin screw extrusion line is capable of volume output in excess of 1,000 lbs/hour (454 kg/hour), a necessity for supporting high volume production. Traditional strand cutting and underwater pelletizing are available, the latter for low durometer materials such as urethanes and thermoplastic elastomers (TPE) used in flexible bandage, film and tubing applications.

Minimally Invasive

Today’s minimally invasive surgery techniques involve incisions small enough for a surgeon to insert a catheter into a blood vessel, through which instruments and devices can be inserted to treat diseased blood vessels, clean out blocked vessels, or deliver clot‐dissolving medications directly at the problem area.

Vascular catheters used in minimally invasive surgery face a number of design challenges. While they must be fairly stiff at their proximal end to allow the pushing and maneuvering of the catheter as it progresses through the body, they must be sufficiently flexible at the distal end to allow passage of the catheter tip through the smaller blood vessels without causing significant trauma to the blood vessels or to the surrounding tissue.

This combination of flexibility, high tensile strength and compression resistance is what makes designing a vascular catheter challenging. Selecting the appropriate polymer for an optimum catheter design requires an understanding of the biological, physical and chemical characteristics as well as a thorough knowledge of the polymers that are commercially available.

Increasingly, permanent and bioresorbable polymers are being enhanced with additives to increase therapeutic effect.  These include radiopaque fillers for x-ray visibility, bioactive bone growth additives and other active ingredients.

Custom compounding such materials requires facilities, equipment and processes necessary for implantable applications.   All batching and hot-melt extrusion processes must be conducted in a clean environment: ISO 100,000 class cGMP certified clean room at a minimum.

Twin screw extruders are often required to provide optimal distributive and dispersive mixing when melt blending liquid and powdered additives into an implantable polymer matrix.  Small scale twin screw extruders are required from an economic standpoint as ingredients for enhanced orthopedic implants are relatively expensive.  

Pre and post extrusion equipment is also highly specialized for implantable polymers.  Desiccant and vacuum driers are required to prepare active ingredients in fine powder form and pellets of bioresorbable polymers with low melt temperatures.  Polymers having dissimilar bulk densities are best fed into the extruder separately using multiple single screw loss-in-weight feeders.  Fine power additives are also fed separately using twin screw or disk type loss-in-weight feeders.  Liquid ingredients are injected into the melt blend with peristaltic, gear, piston, or syringe pumps. Post extrusion cooling of the polymer blend is essential for precise sizing and metering.  Long term implantable polymers are cooled using water while bioresorbable polymers must be cooled with a dry air supply.  In both cases the cooling medium must be clean and maintained at a specific temperature.

Regulated Devices

The FDA may require biological evaluation of medical devices to determine the potential toxicity resulting from contact of the component materials of the device with the body.  According to the FDA, the device materials should not, either directly or through the release of their material constituents:

produce adverse local or systemic effects;
be carcinogenic;
produce adverse reproductive and developmental effects.
The appropriate tests for biological evaluation of a medical device is determined by the chemical characteristics of device materials and the nature, degree, frequency and duration of its exposure to the body.  In general, the tests may include: acute, sub-chronic and chronic toxicity; irritation to skin, eyes and mucosal surfaces; sensitization; hemocompatibility; genotoxicity; carcinogenicity; and, effects on reproduction including developmental effects.  Additional tests may be necessary for some devices.

The International Standards Organization (ISO) developed a standard for biological evaluation of medical devices (ISO 10993) to evaluate the effects of medical device materials on the body.  This standard provides guidance for selecting the tests to evaluate the biological response to medical devices, and appropriate methods to conduct the biological tests.

High Performance

Plastics are used in a wide range of applications and markets.  Even in commoditized markets, such as consumer goods, custom compounders play a key role in tailoring plastics for specific applications.  Compounding volumes for these markets are often substantial, and require suppliers with large equipment and high throughput.

Many other markets require more specialized material solutions.  In semiconductor, aerospace, military, electronics and countless other industries, high performance polymers and specialty additives to enhance key properties are more common.  Equally, material specifications and quality standards are of primary importance.  In many instances, these markets require the same quality, consistency and performance that Foster has been providing medical device companies since our inception.

While our primary focus is medical, we have a rich history of providing innovative polymer solutions to other industries that value our expertise in performance polymer compounding.
