CleanFUZE™ Technology

DiFUSION Technologies, Inc.
Georgetown, TEXUS

• CleanFUZE™ is a blend of PEEK and Silver Zeolite that results in a new orthobiologic load-bearing biomaterial that promotes bone growth osteoconductively and osteoinductively while simultaneously fighting potential surgical site infections (SSIs).

• It is a self-sterilizing osteoconductive polymer which resists infection and biofilm adhesion. CleanFUZE™ is not a coating, but a new biomaterial, which can be machined into load bearing, stand-alone spinal implants.

• It can also be applied to all metal orthopedic and dental implants through a proprietary encapsulation process.

• CleanFUZE™ is the first antimicrobial polymer which also contributes to the osteointegration of the implant.

Advanced Manufacturing Of Ceramics For Biomedical Applications: Subjection Methods For Biocompatible Materials

A crucial aspect related with the eventual manufacturing or prototyping of parts of advanced ceramic cups is the machining processes involved.

Ceramic cups are used in field of prosthetic implantalogy

* Design of a complete machining route
* Development of the innovative and tailored subjection systems
