Offering engineering services in the design and development of high-reliability drug-infusion systems manufactured from biocompatible medical-grade extrusion materials, Forefront Medical Technology is a fully integrated contract manufacturer. Its development expertise includes rapid prototyping by means of selective laser sintering, and the company additionally offers capabilities in in-house toolmaking, injection molding, extrusion, Class 10,000 cleanroom assembly, testing, packaging, sterilization, and global logistics. It has developed a pump tube assembly that forgoes conventional bond joints, instead attaching the extruded silicone pump tube to the mating hubs by means of a self-locking feature that eliminates leakage.

Extrusion of flexible medical tubing
Grayline Inc. employs standard and special extrusion equipment to manufacture custom flexible medical tubing in a range of sizes and geometries. The company’s extruded tubing is available in a variety of nontoxic materials, including PVC, thermoplastic elastomers, polyurethanes, and polyethylene compounds. It also offers custom tubular shapes and tubes with a connector or fitting inserted in each end. Tight dimensional tolerances are controlled by means of laser micrometry, which is also used to support the collection of full production-lot data.
Variable-flexibility extrusion technology
A provider of advanced extrusion services uses proprietary Taper-Tie continuous-extrusion technology to make variable-flexibility tubing for catheter shafts requiring high flexibility at one end for forward navigation and rigidity at the other to facilitate directional control by physicians. Specializing in the production of minimally invasive medical devices, Putnam Plastics Corp. designed the technology to replace traditional manual assembly of catheters with segmented shafts and eliminate associated labor costs. The continuous manufacturing method produces a catheter shaft that has variable properties along its length from the moment it is extruded. The process allows for quickly changing from rigid to soft grades of a designated polymer along the shaft while simultaneously reducing wall thickness during the extrusion.
