Although the endovascular repair of abdominal aortic aneurysms is a less invasive alternative than classic open surgery, complications such as endoleak and kinking still need to be addressed. Numerical simulation of endovascular repair is becoming a valuable tool in stent‐graft (SG) optimization, patient selection and surgical planning.
The experimental and numerical forces required to produce SG...
A new concept of monolithic spinal rod with variable flexural stiffness is proposed to reduce the risk of adjacent segment degeneration and fracture associated with rigid spinal fixation techniques while providing adequate stability to the spine. The concept is based on the use of Ti–Ni shape memory alloy rods subjected to different processing schedules implying local annealing, cold work, or a combination...
