Gastroenterologist Professor Shaheen Handy recognised an unmet need to treat people with swallowing difficulty (dysphagia) and invented a solution to address this involving electrical stimulation to the patient’s pharynx to restore neurological control. The design challenge was to translate the complex research expertise into a product suitable for routine use in a hospital and could be commercially successful. A start-up company Phagenesis was set up to lead the product to market with Maddison supporting the design of the unit and disposable catheter.
As well as meeting the functional requirements, the Phagenesis Dysphagia Treatment System had to conform to the relevant standards including IEC 60601 (electrical medical systems), 62366 (usability) and 10993 (biocompatibility) and ensure that no harm could come to the patient through system error or foreseeable misuse.
The product had to be simple to use, easy to clean, robust, cost effective and easy to manufacture. The industrial design needed to communicate a high quality aesthetic to support the Phagenesis brand. Maddison were brought in at the early design stage to drive the mechanical and industrial design aspects of the product development.
Maddison took the design from the early stages right through to production and post production support. We worked closely with an electronics and software partner to ensure a completely integrated approach to the design. As well as the design of the base unit, we supported the design of the disposable combination nasal feeding tube/electrode. Maddison also designed the User Interface and graphics in collaboration with the Phagenesis team, to create the finished product, the Phagenesis Dysphagia Treatment System.
