Conformis Launches iUni® G2 Next Generation Platform for the Only Patient-Specific Unicompartmental Knee Replacement

Burlington, Mass. – December 14, 2009

Surgeon Feedback and Advanced Engineering Combine to Create a Wear Optimized Implant with an Even Easier Surgical Technique

Key Facts:

  • Conformis, Inc. is taking the next step in the evolution of patient-specific technology by launching a new iteration of its unicompartmental knee resurfacing device, the iUni G2.
  • Enhancements to the iUni G2 include an improved, patient specific and wear optimized design, instrument changes for even simpler surgical techniques, and iView patient-specific images for improved surgical planning.
  • Conformis’ partial knee resurfacing systems use proprietary technology and patient-specific imaging data to personalize an implant and instrumentation set for each patient, providing superior fit and performance.
  • Conformis introduced the iUni G2 in November 2009, and it is currently available for both medial and lateral compartment treatment.
  • Dr. Terry Clyburn and Dr. Brian Parsley performed the first iUni G2 surgery during a live broadcast from Foundation Surgical Hospital in Bellaire, Texas. The surgery is currently available for viewing.

The iUni G2 Advantages:
Conformis’ patient-specific approach offers an array of advantages to patients, surgeons and hospitals. These benefits include:

  • Patient-specific fit and wear optimized design: The iUni G2 offers patient-specific, anatomic fit for natural kinematics, full coverage of all weight bearing areas and a new implant designed for low contact stress and micro-motion.
  • Minimally invasive and minimally traumatic procedure: Patients benefit from a resurfacing solution with minimal bone resection, preservation of all ligaments, no intramedullary canal penetration, and the ability for a simple conversion to a primary total knee arthroplasty.
  • Simple and reproducible surgical technique: Conformis’ iUni G2 surgery uses iJig® patient-specific instrumentation to reduce the number of surgical steps and to minimize intra-operative sizing and trials. In addition, the new iView patient-specific planning images introduce an entirely new and simple way to visualize joint preparation during surgery.
  • Operating room efficiencies: The iUni G2 provides an assortment of efficiency benefits to surgeons and hospitals, including simplified set-up and tear down, minimal instrumentation for the surgery, complete system delivery in a disposable kit and reduced sterilization and inventory costs.

Philipp Lang, MD, CEO of Conformis: “The iUni G2 system was designed with surgeon feedback over the last 18 months. We believe the technology is a meaningful advance not just in the implant characteristics, but also in the experience that surgeons will have in the operating room. It’s the next evolution in the Conformis patient-specific experience.”

Dr. Terry Clyburn, MD: “With its iUni G2, Conformis has continued to lead the industry in patient-specific approaches to orthopedics. This product not only offers patients an array of benefits, but also provides surgeons with additional features that create a more streamlined surgical process. Conformis’ ability to listen to surgeons and provide rapid updates is a testament to the advantages of their just-in-time model.”
