 The Crosstrees PVATM PodTM is a device designed to percutaneously provide controlled delivery of PMMA bone filler material during vertebral augmentation. The Crosstrees PVA System for Percutaneous Vertebral Augmentation PVA is designed for use with Crosstrees Fortibrae PMMA. The system is novel in providing the ability to control the delivery of PMMA to the vertebral body without the need for an additional permanent implant to remain within the patient. The Crosstrees System for Percutaneous Vertebral Augmentation will be used with Crosstrees Access Tools, which are regulated as Class I exempt orthopedic manual surgical instruments.
