Solvay Specialty Polymers and Secant Medical®, a leading manufacturer of custom biomedical textile structures for medical devices, have formed a marketing partnership to promote the development and production of implantable biomedical fabric structures made of Zeniva® PEEK (polyetheretherketone) fiber.

New Supply Chain Formed

The collaboration will result in the formation of a new supply chain that will provide medical OEMs with options to develop custom implantable fabrics made of Zeniva PEEK for therapeutic devices in orthopedics, cardiovascular, tissue engineering, neurology, and general surgery.

The partnership further solidifies Solvay’s position as a strategic materials supplier to the healthcare industry and expands Secant Medical’s leadership position in biomedical textiles engineering.

Custom Woven, Knitted and Braided Fabrics

Secant Medical uses high-performance metallic and polymeric biomaterials in various combinations to manufacture a range of woven, knitted, and braided fabrics for implantable devices. Custom applications include high-strength sutures, bone anchoring devices, rotator cuff and arthroscopic joint repair, spinal stabilization and disc repair and replacement, textile-based heart valves and vascular grafts, and lightweight textile mesh structures for a variety of surgical procedures that require tissue reinforcement and wound support.

Implantable Brain Shunts and Access Ports

Implantable brain shunt valves and access ports from France-based Sophysa, a leading supplier of adjustable neurosurgical valves for hydrocephalus treatment, are made of Eviva® polysulfone (PSU) resin from Solvay.

The BoneBac® TLIF spacer, made from Zeniva® PEEK rod, is a transforaminal lumbar interbody fusion spacer. These spacers are implanted in the lumbar disc space to enable fusion of the adjacent bony surfaces of the vertebrae. Minimally invasive surgery is made easier with the BoneBac® TLIF spacer due to its patented geometry that allows for direct injection of graft while the inserter is still attached, thus resulting in a more complete fill when packing the disc space.

Extremity Medical LLC, Parsippany, N.J., an entrepreneurial-based manufacturer of orthopedic implants for the distal extremities, received 510(k) clearance from the U.S. Food & Drug Administration (FDA) for its new HammerFiX™ IP fusion system made of Zeniva® polyetheretherketone (PEEK). The HammerFiX™ implant is the first cannulated hammertoe device made of the non-resorbable polymer PEEK in the U.S., according to Jamy Gannoe, Extremity Medical’s president and co-founder. It is used for the fixation of osteotomies and reconstruction of the lesser toes following correction procedures for hammertoe, claw toe, and mallet toe.

“Zeniva® PEEK’s exceptional properties have enabled us to develop a next-generation hammertoe fixation product that is differentiated among our competition in terms of material and design,” said Gannoe.

BioVentrix’s innovative Revivent™ Myocardial Anchoring System for the treatment of congestive heart failure features a tether component made of Zeniva® PEEK resin, selected for its for high strength and biocompatibility. The CE-marked heart failure therapy makes possible Less Invasive Ventricular Enhancement (LIVE™), a procedure that restores the left ventricle from damage done by a heart attack to a more optimal volume and conical shape, thereby enhancing the performance of the heart’s non-damaged myocardium and improving quality of life. (View video at: http://bioventrix.com/physicians/).

The unique anchoring system consists of two polyester fabric-covered anchor heads made of titanium. A flexible tether made of Zeniva® PEEK functions as a type of zip tie and is used to squeeze the anchors together and hold them in place. BioVentrix machines a flat PEEK sheet with a thickness of 0.1016 cm (0.040 in) into rectangular shapes that are 0.1016 cm wide x 0.1651 cm deep x and 30.48 cm long (0.040 in. x 0.065 in. x 12 in.). The anchor heads and tether are attached with eyelets and cam locks.
