It is widely known and published that modern sterilization techniques used in the healthcare industry can have a detrimental effect on thermoplastic polymers. In particular, gamma sterilization, which is the most common ionization method, can cause substantial changes to occur in polymeric materials. Polymer chain scission and cross linking can both occur, altering the physical properties and appearance of materials and ultimately affecting the functionality of a device utilizing these materials. RTP Company’s TPE (Thermoplastic Elastomer) Division has initiated a series of projects to measure the effect different sterilization methods have on RTP Company’s standard TPE products used in medical devices. This paper discusses the effect gamma sterilization has on these various TPE compounds produced by RTP Company for the healthcare industry.
Different types of screw threads have evolved for fastening, and hydraulic systems. Of special concern are plastic-to-metal, taper/parallel threaded joints in hydraulic circuits. A discussion and recommendations are provided to create an awareness of different types of threads and how they are used.
Calibration, maintenance, and validation activity, despite operating within the same department in some organizations, have generally been managed separately, each with their own procedures and their own computerized management systems. Since even calibration and maintenance professionals tend to access records differently and track different types of information, these separate and unconnected systems made sense. However with new regulatory pressures and in search of greater productivity and efficiency, leaders in the life science industries have explored and experimented with different ways to harmonize these systems. Until recently, the available options have required significant compromises to be made. This paper discusses the evolution of the driving forces and the available solutions for harmonizing calibration, maintenance and validation, concluding with the latest technologies designed to eliminate the need for the departmental compromises previously required to achieve harmonization.
Teleflex Medical OEM, in conjunction with researchers at the University of Connecticut, has developed a tough, high-modulus composite with potential for bone fixation. Fabricated from a unidirectional, fibrous PLLA/apatite, the composite exhibits excellent mechanical properties which correlate to those of natural bone while featuring excellent surface bioactivity. The entire composite is bioabsorbable whereby a device made from the composite will gradually be replaced by natural bone tissue at the implantation site. Early studies indicate integration can occur firmly and permanently with the surrounding tissue. In addition, such prepared composites may have the potential to be used to control the release of growth factors to enhance bone cell stimulation.

A variety of linear motion devices are available today for performing the function of single-axis movement, whether it be for an assembly operation, testing, packaging or simple motion control. This white paper will seek to define the various types and define the options to be considered when deciding whether to build or buy a single-axis actuator, also known as a linear guide, slide or table in the parlance of particular industries.
Medical device manufacturers have long marketed their products with limited concern for costs. But today, an aging population and skyrocketing medical costs are prompting private insurers and government payers worldwide to limit reimbursements for medical devices. Medical device manufacturers are responding in two ways, by: * Justifying product price points by carefully documenting their value in improving patient outcomes. * Reducing costs throughout their operations by rethinking how they sell and market their products, outsourcing operations, and implementing lean manufacturing principles. Download this white paper by clicking on the link below and learn how enterprise software enables medical device manufacturers to more successfully implement these price justifications and cost cutting initiatives.
