Automated Sewing Process of a Trans-Catheter Heart Valve

Abstract: The current development of one trans-catheter heart valve (THV) consists of a multi-stage operation that takes over fifteen hours to complete. One of these stages is a 41 -minute, ground-level sewing operation, in which a highly skilled operator will sew an implantable cloth onto a valve frame template. Due to the immense dexterity required to operate this process, automation of a standardized sewing process has been identified as a must to meet industry standards and rising demand. We hope to develop a single automated system that will interchangeably mass produce the different models of the THV, a procedure known as S.M.E.D (Single Minute Exchange of Dies). Previously, we designed a robotic sewing device, based on the experimental hand trajectory from a human operator sewing an implantable cloth using a motion capture system. The data analysis of the manual sewing process showed that the workspace of the manual sewing process can be reduced to 3D-planar. A prototype was developed and tested, comparing the human manual sewing trajectory to the robotic device. Tests showed the robot could closely follow the experimentally obtained trajectory of a human operator. We hope to perfect the trajectory of our sewing device to meet valve standards, to record and measure the tension in the sewing thread, and to integrate a five-axis robotic arm into the system. Once we quantify this force we can develop further accordingly. This process, once complete, may alter the bio-medical field as we know it.
