Medical Device Innovation: Translating Ideas into Reality
Engineering Analysis Tissue Stiffness XrayTo3D wins awards
Simulate the device under normal as well as extreme operating loads and conditions, to check its performance and safety.

1. Create a realistic Finite Element Model of the device.

2. Apply the necessary boundary conditions (constraints and loads).

3. Take special care of meshes, interfaces, and friction coefficients.

4. Verify the model under simple loads first, compare with manual calculations.

5. Validate the results with physical experiments (say, using UTM).

Tissue Stiffness Measuring Device helps in diagnosing diabetic foot ulcer patients. A plastic probe pushes and indents the foot skin, while recording and characterizing the tissue. Development team includes Amit Maurya and Rupesh Ghyar, BETiC, IIT Bombay; and Dr. Rajani Mullerpatan, MGM Hospital.
Current status: The device includes mechanical, electronic and software components, all of which have been developed and assembled. It has been tested by Dr. Rajani's team on both healthy and diabetic patients and the data is being analyzed.

Patent filed: A.Maurya, R. Ghyar, R. Mullerpatan, B. Ravi, "Tissue Stiffness detection device for Diabetic foot".

XrayTo3D technology developed by Vikas Karade, which reconstructs 3D models of bone from their 2D X-ray images, was recognized by 'Gandhian Young Technological Innovation Award' in 2014, and is among the top 10 innovations in India for President's Scholar In-Residence Program 2015.
This innovation has been in the media.
