Medical Device Innovation: Translating Ideas into Reality
Clinical Immersion Auto Suture ICAM-3D, Chennai
Engineers visit hospitals (with prior consent) to observe the clinicians treating patients, and identify areas of potential improvements

1. Meet clinicians to understand the background and nature of medical problem.

2. Study relevant anatomy, medical terms and current solutions.

3. Collect information about equivalent solutions, devices and patents.

4. Record diagnosis and treatment protocols, observe surgeries.

5. Capture the 'voice of customer' - patient, surgeons and other caretakers.

Surgical auto-suture instrument allows surgeons to follow the ideal circular path necessary for perfect suturing. Unlike other such devices in the market, the novel design uses a standard needle, which are easily available at low cost.

Development team includes Dr. Rupesh Ghyar, IIT Bombay; Dr. Hemant Bhansali, Nanavati Hospital and Sridevi Tool Engineers,Vasai

Current Status: The metal prototype has been manufactured, and has been mechanically tested. The design is being improved based on clinician's feedback. The final device will be available for testing by end of 2015.

Patent filed: R. Ghyar,H. Bhansali, B. Ravi, "An automated needle holder and suturing device" 1880/MUM/2013

International Conference on Additive Manufacturing and 3D Printing (ICAM-3D), was organized by ESCI-Institution of Engineers (India), DST and Veltech, in Chennai on 5-7 Feb 2015, and inaugurated by Dr. R. Chidambaram. Prof. B. Ravi gave an invited talk on "Rapid Design, Prototyping and Manufacture of Medical Devices" and also chaired a session on Medical Applications
A key conclusion was that low-cost 3D-printed medical models reconstructed from CT scans can now be widely used for surgery planning, as well as patient education and medical training.
