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.

Abstract: Embodiments herein relate to medical devices and methods for using the same to treat cancerous tumors within a bodily tissue. A medical device system herein can include an electric field generating circuit configured to generate one or more electric fields, and control circuitry. The system can include one or more electrodes disposed on a first stimulation lead to deliver the electric fields to a site of a cancerous tumor within a patient and one or more electrodes disposed on a second stimulation lead to deliver the electric fields to the site of a cancerous tumor within a patient. The first and second stimulation leads can be configured to be implanted on or about a duodenum. The electric field generating circuit can generate electric fields at frequencies selected from a range of between 10 kHz to 1 MHz. Other embodiments are also included herein.

Abstract: Devices, systems, and methods for regulating glucose levels, including treating diabetes, in accordance with the present disclosure may include a catheter having an expandable or inflatable portion, one or more electrodes disposed on the expandable or inflatable portion of the catheter, wherein the electrodes are configured to deliver energy to a patient's gastrointestinal tract, and a drug delivery mechanism for delivering a drug therapy subsequent to energy delivery by the electrodes. A method for regulating glucose levels according to the present disclosure may include inserting a catheter into a patient's gastrointestinal tract, positioning the catheter in a duodenum of the patient's gastrointestinal tract, expanding or inflating a portion of the catheter in the duodenum, the expandable or inflatable portion of the catheter including electrodes, applying energy to the duodenum via the electrodes to ablate tissue of the duodenum, and delivering a drug therapy to the ablated tissue of the duodenum.
