When it comes to material selection, the medical industry is one of the most demanding sectors. Materials employed within healthcare must be durable enough to withstand harsh conditions, resistant to degradation, and, of course, compatible with the human body. One category of materials that continues to gain traction in silicone manufacturing is biomaterials.

At ProMed, we have extensive experience with biomaterial grade injection molded products. Our manufacturing facilities and equipment are designed for a single purpose—to mold medical and implantable silicone, combination components, and biomaterial grade plastics with uncompromising quality and service. We currently have four divisions that are located within two manufacturing sites. All are certified class 10,000 / ISO Class 7 cleanrooms. Our ProMed Molded Products division specializes in the molding of silicone and biomaterial grade plastic components , sub-assemblies, and assemblies.

What Are Biomaterials?

Biomaterials are an area of great innovation within the medical industry, and this sector continues to evolve over time. Initially, molded products made of biomaterials were focused on doing no harm to the patient, and thus, caused no injuries or toxic effects to the patient. As biomaterials advanced, the focus shifted to being a material that is responsive and interactive with local biological conditions. Biomaterials are now defined as “material intended to interface with biological systems to evaluate, treat, augment, or replace any tissue, organ, or function of the body”. For example, if we consider implantable devices, traditional implantables were designed with inert biomaterials that “did no harm” when placed inside the body. However, implantables of today are often focused on interacting and integrating with the biological environment inside the body – and in some cases even biodegrading, or bioabsorbing, over time.

Applications of Biomaterial Grade Injection Molded Products

In the early days of biomaterials in silicone manufacturing, it was challenging to find many applications of injection molded products. However, as innovations were made and companies gained more experience with these materials, biomaterial grade injection molded products are finding a broader range of uses and play a crucial part in biomedical applications. Today’s biomaterials are easily incorporated into existing injection molding processes as no additional equipment is needed to manufacture these materials. Biomaterials include polymers, natural rubbers, polyurethanes, and silicone rubbers. Silicones are a common biomaterial used for injection molded products for the medical sector due to its attractive properties. Silicone offers excellent biocompatibility, chemical resistance, and stability. Silicones also offer a wide range of operating temperatures, are easily sterilized, and are a great choice for injection molding.

Biomaterials serve an important role in biomedical applications. Below are some applications of biomaterial grade injection molded products.

  • Cardiovascular devices: biomaterials are used in a wide range of cardiovascular products including vascular grafts, heart valves, pacemaker leads, artificial heart and ventricular assist device components, stents, balloons, and blood substitutes.
  • Orthopedics: biomaterials are used in various applications to treat musculoskeletal issues including joint replacements, bone defect fillers, fracture fixation plates, and artificial tendons and ligaments.
  • Ophthalmic: biomaterials are integrated into existing treatments for the eyes such as contact lenses, corneal implants and artificial corneas, and intraocular lenses.
  • Drug delivery: biomaterials are used in controlled and targeted drug-delivery systems, and have revolutionized this form of treatment.
  • Spinal implants: biomaterials are becoming an alternative to traditional spinal implants made of titanium, stainless steel or cobalt-chromium. For example, biomaterials are used to fill in the disc space in the spine to treat disc degeneration issues.
  • Soft tissue repair/replacement: biodegradable biomaterials are being considered for tissue engineering and soft tissue repair, such as burn and wound dressings and artificial skin. Researchers on focused on controlling the rate of degrading within the boy as well as the mechanical properties of the material. Bone repairs with biomaterials is also being studied.
  • Gene therapy: there is a great deal of potential in using biomaterials for gene therapy and thus, research is on-going in this area. Biomaterials would be used to carry and target treatment for certain genes within a patient.
  • Miscellaneous: there are several other applications for biomaterial grade injection molded products including dental implants, cochlear implants, urologic implants, and sutures.
