Kiva® VCF Treatment System

A Novel Treatment For Vertebral Compression Fractures

If you’re searching for a different treatment for vertebral compression fractures, be sure to take a look at the KIVA® VCF Treatment System.

Kiva has met or exceeded the performance of balloon kyphoplasty in 3 separate comparative studies. In one or more of these studies, Kiva was shown to:

  • Reduce rate of adjacent level fracture

  • Improve kyphotic angle restoration

  • Reduce rate of cement extravasion

  • Reduce cement volume

The KIVA System is the first new approach to treating vertebral compression fractures (VCF’s) in over a decade. For the first time, physicians can deliver (through a transpedicular approach) an implant with a predictable structure. The implant also serves as a reservoir to contain and direct the flow of cement. It is indicated for use in the reduction and treatment of spinal fractures in the Thoracic and/or lumbar spine from T6-L5. It is intended to be used in combination with the IZI Vertebral Augmentation Cement Kit.

How Does Kiva Work?

Kiva is a Unipedicular System. The Kiva Implant is delivered percutaneously over a removable guide-wire in a continuous loop into the vertebral body through a small diameter, single incision. Physicians can customize the amount of the implant delivered during the procedure to adjust to vertebral compression fracture morphologies. With Kiva, bone cement is delivered simultaneously through both the access cannula and the implant. This eliminates the added steps required by other systems.

Biomechanical & Biomedical Advantages of the Kiva Implant

A bench test material comparison demonstrated that theKiva Implant is 63% less rigid than PMMA bone cement alone, which may reduce the risk of adjacent level fractures.1,2,3

(Compression testing at same rate to identical peak load (.5Hz, 300-3000N))
