Thanks Merel Rumping appreciate the support and look forward to staying in touch! Hope we can find ways to collaborate. Best regards,

Thank you Umuraza Mathilde . Do you work with lower-limb amputees in Rwanda? We would love to be connected with people currently using a prosthetic knee joint for their feedback and insight. You can please reach me at if willing to talk via email. Kind regards

5. "Tell us more about how you integrate your target user group into the design and development of your idea. Are there trainings or capacity building services offered to your target user group?"

Training is a critical factor in success of this product, although to be very clear, D-Rev is not interested in teaching prosthetics. It's not our skill-set, and there are excellent organizations (ISPO, Exceed) that ably and actively fulfill this role by supporting modern, high-quality standards of prosthetic training all around the globe. What we do believe in is supporting our customers, who are highly trained and typically ISPO-certified prosthetists, with the information they need to use our knee with max efficacy. For the ReMotion Knee, we've put together a series of training videos showing fabrication with different socket types commonly used in our target markets, and demonstrating proper alignment and tips for gait training. We're also partnering with practitioners to launch an inaugural day-long credit course in India in July. Each ReMotion Knee also comes with our Instructions for Use: a clearly-worded and highly visual guidebook that indicates proper use, patient selection, and alignment tips. All three of these resources -- the IFU, 1-day course, and video series - were developed with iterations based on multiple rounds of feedback from users.

6. We want know more about your vision for bringing your product to the market. Do you have specific hypotheses you want to test as you expand your model? What are your measures for quality control? Are you manufacturing in the regions you distribute to or is it centralized ? If so, does freight add significantly to cost of your products?

Currently, we manufacture and hold inventory centrally and distribute globally (hub-and-spokes model). We have an excellent and synergistic working relationship with our manufacturing partner, and manufacture in an ISO 13485 (medical grade) facility, having passed ISO 10328 (structural testing for lower-limb prosthetics). As a result ReMotion was able to receive CE mark and is registered with the FDA, standards we would hold ReMotion Pro to as well. With the $80 ReMotion Knee we demonstrated this level of quality could be achieved with an affordable end-user price. Internally at D-Rev we follow professional quality control procedures and recently passed a routine FDA audit.

Freight does add to the cost of the product, but we've been fortunate to have an excellent partnership with DHL which allowed us into their NGO program and offers door-to-door global shipping (destinations outside the USA) at a fraction of their typical rates. We've gotten rates down to approximately $5-10 / knee for most countries for a typical small order, and less for higher volumes. We've shipped successfully to customers in 20 countries, including arranging complex pick-ups from individual patients and returns management. This is an area we think we can add value by offering smooth and cost-effective service to customers used to difficult logistics and long lead times, and continue to improve in coming years.
