Abstract: An example medical device is disclosed. The example medical device includes a tubular scaffold having an inner surface and an outer surface. The medical device also includes a flexible inner member extending along at least a portion of the inner surface of the scaffold. Further, the medical device includes an activation assembly positioned along a portion of the inner member, the activation assembly including a conductive member having a first end region and a second end region, wherein a portion of the first end region is coupled to an activation element, and wherein the second end region is coupled to a power source. Additionally, the power source is configured to deliver an electrical stimulus to the activation element which shifts the inner member between a first configuration and a second expanded configuration.

Abstract: Embodiments herein relate to non-invasive bladder cancer detection systems and methods. In an embodiment, a method for detecting a disease state in a subject is included. The method includes obtaining a liquid biological sample from the subject and placing it into a container and contacting the liquid biological sample with a first chemical sensor element, where the first chemical sensor element can include a plurality of discrete graphene varactors. The method can include sensing and storing capacitance of each of the discrete graphene varactors to obtain a first sample data set. Other embodiments are also included herein.
