BOULDER, Colo.--(BUSINESS WIRE)--Crosstrees Medical, Inc. today announced that it has completed enrollment of the company sponsored pivotal IDE study, “Clinical Evaluation of the Crosstrees™ PVA Pod System in Symptomatic Adult Patients with Acute Vertebral Body Compression Fractures at T4-L5.” Devices using Crosstrees® Pod technology feature a polymer material to control the delivery of a specific volume and geometry of PMMA bone cement to the vertebral fracture site. Following PMMA delivery, the construct is opened and removed from the vertebra, leaving only the PMMA filler material, without the need for an additional implanted device in the spine. Research staff at Crosstrees developed the technology to address the need for improved vertebral fracture repair devices designed to reduce risk of complications in vertebral augmentation, such as nerve root compression, pulmonary embolism, and arterial embolism as reported in the published literature.
