Evaluation of a Shape Memory Alloy Reinforced Annuloplasty Band for Minimally Invasive Mitral Valve Repair Molly F. Purser, PhD, Andrew L. Richards, MS, Richard C. Cook, MD, Jason A. Osborne, PhD, Denis R. Cormier, PhD, Gregory D. Buckner, PhD The Annals of Thoracic Surgery Volume 88, Issue 4, Pages 1312-1316 (October 2009) DOI: 10.1016/j.athoracsur.2009.04.133 Copyright © 2009 The Society of Thoracic Surgeons Terms and Conditions

Fig 1 (A) Prototype band at 24°C (martensitic phase) is easily straightened; (A–D) changes in shape and stiffness during heat-induced phase transformation (elapsed time approximately 5.0 seconds); (D) band at 37°C (austenitic phase) in final shape.

Fig 2 Endoscopic images show (A) normal, (B) failed, and (C) repaired mitral valve for prototype band, and (D) normal, (E) failed, and (F) repaired mitral valve for Physio band. Arrow indicates flail leaflet. The Annals of Thoracic Surgery 2009 88, 1312-1316DOI: (10.1016/j.athoracsur.2009.04.133) Copyright © 2009 The Society of Thoracic Surgeons Terms and Conditions

Fig 3 Compression test results show stiffness of prototype band at 24°C (martensitic phase) and at 37°C (austenitic phase) in comparison with commercial bands.

Fig 4 Pictures from robotic evaluation show flexibility of (A, B) Physio ring (Edwards Lifesciences, Irvine, CA) and (C, D) prototype band. Arrows indicate tissue deformation and suture tension. Dotted line highlights mitral annulus. The Annals of Thoracic Surgery 2009 88, 1312-1316DOI: (10.1016/j.athoracsur.2009.04.133) Copyright © 2009 The Society of Thoracic Surgeons Terms and Conditions

Fig 5 (A–D) Prototype band deployed through an 8-mm trocar; (E, F) Physio band can not be deployed through the trocar. The Annals of Thoracic Surgery 2009 88, 1312-1316DOI: (10.1016/j.athoracsur.2009.04.133) Copyright © 2009 The Society of Thoracic Surgeons Terms and Conditions
