Dr. Amy Throckmorton and Colleagues Receive a US Patent for an Integrated Cutting Guide with Cardioprotective Butterfly December 30, 2021 Dr. Amy Throckmorton, associate professor and director of the BioCirc Research Laboratory in the School of Biomedical Engineering, Science and Health Systems, and colleagues (Co-inventors R. Stevens, A. Moulick, and V. Mahan) received US patent No. 11,202,645, assigned to Drexel University, for an “Integrated Cutting Guide with Cardioprotective Butterfly for Repeat Sternotomy and for Cast Cutting.” Pericardial patches are used prior to closing a patient's sternum after a sternotomy. Dr. Throckmorton’s and her colleagues’ patent is for a device that consists of a cardioprotective patch with an integrated cutting guide that includes a membrane and that would be beneficial to provide a pericardial patch that can reduce complications associated with a repeat sternotomy, as well as to provide a mechanism integrated into the patch to assist in performing the repeat sternotomy. As an added benefit, it would be beneficial to apply the mechanism to cutting a cast, such as to remove a cast after the healing of a broken limb.
