The University of Colorado (CU) has executed a license agreement with Aurora, CO-based ValveXchange, Inc., for a process to transform cardiac imaging data into high-quality, three-dimensional models used for heart valve product development, clinician training, and pre-procedure planning. The CU technology converts data from routine medical imaging of soft tissues — ultrasounds and CT and MRI scans — into 3D models, which are then transformed into physical models using 3D printers. ValveXchange is developing an artificial heart valve that has the advantages of existing tissue-based heart valves but can be implanted and replaced through a small incision between the ribs. The approach is expected to replace traditional open-heart surgery for many heart valve procedures. The 3D heart modeling technology allows the company to develop replacement valves using patient-specific heart anatomy examples, and later to train physicians in implant techniques in a highly realistic manner. “We expect this advance in 3D heart modeling to provide ValveXchange with a real advantage in the market space,” says company CEO Larry Blankenship.<\/p>\n
