“Kenya has one of the highest incidence rates of esophageal cancer in the world with a rate of 17.6 per 100,000.”  That means there are 9,463 Kenyan patients per year. This is four times higher than the incidence rate in the US. . The cancer is often only noticed toward the later stages allowing only for palliative care (restoring esophageal patency). Therefore, patients usually have no or improper treatments, which leads to higher death rates and suffering more during their end-of-life care. .
A low-cost solution to restoring esophageal patency and, thus, quality of life for patients with terminal cancer does not yet exist. Currently the average Kenyan has the option of depleting their savings for a proper stent or they resort to improper treatments.
The Purdue Innovation
Our model aims to reduce the cost of the esophageal stent to less than $10 USD. This is accomplished by manufacturing the stent with a low-cost material that can be procured in Eastern Africa. This allows for the device to be easily manufactured locally to contribute to their economy and provide a stable supply of quality low-cost stents.
