The broader impact/commercial potential of this I-Corps project includes smart algorithm-driven superior stents for use in Urology, Gastrointestinal surgery, ENT surgery and Neurosurgery. Patients suffering from malignant obstruction, benign biliary strictures, biliary leaks, bile duct stones, transplants, pancreatic strictures due to malignancy, pancreatic fistulae, chronic pancreatitis, and pancreas divisum would potentially benefit from this technology. Almost 112,000 people are treated for these conditions every year in the U.S. The invention is expected to significantly improve performance over currently used plastic/teflon based stents and also augment functionality on many fronts.This I-Corps project will focus on assessing the market requirements to refine the design of a novel Multi-Axis Deformable Sensor/Actuator that is based on the principle of tensegrity. It offers a lightweight actuator system with 6 degrees of freedom of manipulation. This provides the opportunity to create 3-dimensional structures that can be delivered to a desired anatomical/surgical site in the human body for the purpose of repairing strictures, in a low profile and can be expanded to the desired shape. This system offers a new generation of intra-body luminal space maintainers, stents, and expanders. The main value proposition is guaranteed stent retention. The device involves smart algorithms that sense the states (angles, loads) of the system and locally activates them to achieve a desired spatio-temporal support. These algorithms are run in real-time, in embedded processor.

该 I-Corps 项目的更广泛影响/商业潜力包括用于泌尿外科、胃肠外科、耳鼻喉外科和神经外科的智能算法驱动的优质支架。 患有恶性梗阻、良性胆道狭窄、胆漏、胆管结石、移植、恶性肿瘤引起的胰腺狭窄、胰瘘、慢性胰腺炎和胰腺分裂的患者可能会从这项技术中受益。在美国，每年有近 112,000 人因这些病症接受治疗。与目前使用的基于塑料/聚四氟乙烯的支架相比，该发明预计将显着提高性能，并在许多方面增强功能。该 I-Corps 项目将重点评估市场需求，以完善基于张拉整体原理的新型多轴可变形传感器/执行器的设计。它提供了具有 6 个操纵自由度的轻型执行器系统。这提供了创建 3 维结构的机会，该结构可以以低调的方式输送到人体所需的解剖/手术部位，以修复狭窄，并且可以扩展到所需的形状。 该系统提供新一代体内管腔空间维持器、支架和扩张器。主要价值主张是保证支架保留。该设备涉及智能算法，可以感知系统的状态（角度、负载）并在本地激活它们以实现所需的时空支持。这些算法在嵌入式处理器中实时运行。
