Electrosurgical Foreceps

The BEAR team was asked to develop better electrosurgical foreceps. Our physicists and engineers made several prototypes that were tested in our labs on beef liver. A new coating system resulted in foreceps that last 3 times as long during surgery. The foreceps have been approved by the FDA and by the European equivalent of the FDA.

Blood Vessel Connection Device

BEAR has performed design review and mechanical analysis for numerous biomechanical devices. One device was a blood vessel connection device. The device was manufactured from an extremely ductile shape memory alloy. The fabrication of this device was a complicated multistep process, and required detailed knowledge of the strains present in the component during each step. BEAR performed a 3D dynamic finite element analysis and closed form solutions to this process.
