Northwestern researchers develop 3D-printed vascular stents

Researchers at Northwestern University have designed a new 3D printer to create solid and biodegradable structures like vascular stents, according to a recent publication.
The technique, call Mircro-Continuous Liquid Interface Production (microClip), was highlighted in a recent Materials Today article.

The researchers also published a paper about their work in the journal Materials Today Chemistry.

While stents are effective at improving patients' lives, the devices do have issues such as causing inflammation or causing future blockage, according to the article.

"The need for improved manufacturing techniques and materials to create personalized medical devices to improve the outcome of medical procedures," was the stimulus leading to the development of the new technique, Guillermo Ameer said in the article. Ammeer is a BMES fellow and he worked with BMES member Cheng Sun.

The technique developed by the researchers has worked well.

“By marrying the new materials and the high-resolution 3D printing process, it is possible to tailor the stent to address an individual patient's needs, all at high fabrication speed and precision,” Sun said in the article.

The research will next move to live animal studies.
