Alasdair Barnett-Endocuff a Colonoscopy Device

At Design Interviews

(Excerpt) Interview with Alasdair Barnett : Frank Scott: What is the main principle, idea and inspiration behind your design?. Alasdair Barnett : The main source of inspiration came through the practical difficulties in a conventional colonoscopy, including the colonoscope slipping back, the forces required to push can be quite high causing patient discomfort, the tip can move during procedure and is difficult to stabilise and current scopes can miss legions that hide behind colon folds and there is no way to view behind folds. These factors created the design challenge that DesignEdge needed to meet on a technical and aesthetic level, effectively these medical problems were the basis to the inspiration and an eventual solution. .Frank Scott: What has been your main focus in designing this work? Especially what did you want to achieve?. Alasdair Barnett : The main focus was to design and develop an innovative disposable device that slips onto the end of conventional colonoscopes to improve mucosal vision and enhance tip control. With sixty million procedures worldwide this innovative product will revolutionise detection rates within cancer screening. .Frank Scott: What are your future plans for this award winning design?. Alasdair Barnett : We are currently exploring various markets and future product derivatives. We will contunue to find simple and effective solutions to everyday problems in medical endoscopy. .Frank Scott: How long did it take you to design this particular concept?. Alasdair Barnett : Approximately 2 years. .Frank Scott: Why did you design this particular concept? Was this design commissioned or did you decide to pursuit an inspiration?. Alasdair Barnett : The work was commissioned. After the preliminary testing phase we focused on a design that utilised flexible hairs to grip the side of the colon wall. The collapsible hairs fall flush with the EndoCuff maximising user comfort whilst the device is inserted. The tip hairs fold in to be as small as possible during insertion and while the colonoscope is forced forward. When the scope is extracted the hairs then open out enabling the surgeon to view the colon wall behind the folds whilst the scope is being slowly extracted. .Frank Scott: Is your design being produced or used by another company, or do you plan to sell or lease the production rights or do you intent to produce your work yourself?. Alasdair Barnett : Arc Medical Design manufacture and market EndoCuff. .Frank Scott: What made you design this particular type of work?. Alasdair Barnett : DesignEdge specialises in the design of simple and effective medical devices for high volume manufacture. DesignEdge offers a complete design and engineering service to both local and national companies, taking designs through from initial sketches all the way to manufacture. .Frank Scott: Where there any other designs and/or designers that helped the influence the design of your work?. Alasdair Barnett : Early research explored the natural world including animal skins and fish scales for forward friction traction. Hydroscopic and nano-coatings were explored to improving colonscope movement. .Frank Scott: Who is the target customer for his design?. Alasdair Barnett : Patients that require a colonoscopy procedure. .Frank Scott: What sets this design apart from other similar or resembling concepts?. Alasdair Barnett : EndoCuff is a unique and innovative device. .Frank Scott: How did you come up with the name for this design? What does it mean?. Alasdair Barnett : We need a name to reflective the twin values of medical endoscopy and a device to fit the end of a colonoscope. .Frank Scott: Which design tools did you use when you were working on this project?. Alasdair Barnett : SolidWorks 3D CAD Software, SolidWorks Simulations .Frank Scott: What is the most unique aspect of your design?. Alasdair Barnett : EndoCuff features soft flexible projections which gently support the tip of the colonoscope in the centre of the colonic lumen during extubation so providing greater stability and reducing sudden slip back and juddering. This also reduces looping and patient discomfort and pain. The projections evert large folds and flatten small folds so t.[ End of Excerpt: Read complete interview with Alasdair Barnett on Endocuff A Colonoscopy Device at design-interviews.com ]
