Abstract: Described herein are medical apparatuses, formulations, manufacturing processes, and medical procedures relating to drug eluting rubber bands that may be used for banding procedures such as hemorrhoid ligation. Examples of therapeutic agents that can be eluted for therapeutic effect include local anesthetics, opioids, calcium channel blockers, antibiotics, sclerosing agents, and steroids.

Abstract: A device comprising a three-dimensional polymeric element and an electronic element integrated with the polymeric element is disclosed. The electronic element is made up of one or more electrode(s) each individually connectable to a measuring device and/or a controller, and each independently having a thin electrically-isolating layer deposited thereon such that the electrode is exposed to an environment surrounding the electrode at one or more pre-determined locations over the electrode. The device can include cells and/or tissue and/or a therapeutically active agent incorporated within the polymeric material. Processes of fabricating the device, systems for operating the device and methods utilizing same are also disclosed.
