When someone hears the word “bioprinter,” it likely conjures up images of bulky hardware buzzing loudly on a desk in a brightly lit laboratory. Early testing suggests the tiny bioprinter could help heal gastrointestinal tissue damage and potentially seal hemorrhages, all without the need for invasive surgery. Designing a printer the size of a jelly beanThe idea for an ingestible bioprinter stems from a major roadblock in how healthcare professionals treat gastrointestinal disease. When deployed, the ingestible bioprinter was able to extrude a sealant and induce coagulation, effectively closing the simulated hemorrhage. What remains unclear, though, is when, or even if, a procedure using this bioprinter will become available to the general public.
