Team Brady is working in collaboration with the Medtronic Foundation to assess and address the barriers to pacing therapies in India. After multiple field studies, the team has observed ineffective management of bradycardic patients in emergency situations. Proper care is stifled by the inaccessibility of temporary pacing, which is a bridging therapy to a permanent pacemaker. In particular, in low-resource settings where imaging technologies and infrastructure do not exist, patients either die before reaching a cardiologist or reach a cardiologist in a life-threatening state.

To address the lack of availability to temporary pacing, Team Brady is developing an assistive device to allow doctors in settings without imaging to safely and confidently temporarily pace a patient. The assistive device is a hybrid needle system that ensures safe venous access by mitigating the potential risks of a blind procedure. The main components of the device are a mechanical needle-syringe system that allows for larger needle integration without compromising the placement on the patient’s neck and a double-aspiration method that allows the physician to confirm access into the jugular vein twice during the procedure. These components as a system were designed to ensure patient safety, encourage physician confidence, and standardize venous access protocols.
