Using a 3D printer , scientist have made an elastic tissue layer that intimately mimics the outer layer of the heart ’s wall .
The new membrane , which was described Tuesday ( Feb. 25 ) in the diary Nature Communications , contains diminutive sensors that can track the heart ’s temperature , pH and point of strain . The gadget could one daytime be used to treat patients with rhythm disorders in the lower chambers of the centre , as well as the musical rhythm disorderliness atrial fibrillation , the research worker said .
The outer layer of the heart was made of silicon embedded with tiny sensors. The heart layer was made on a 3D printer
Heart round irregularities are a common problem , with one of the most well - known forms , atrial fibrillation , affecting 3 million to 5 million people in the U.S. every year . Left untreated , rhythm irregularities can stimulate blood clot , which can lead to stroke .
masses with atrial fibrillation are often deal with blood thinners or other treatment that may ablate the nitty-gritty ’s pacemaker cell and put back them with electrode . But these techniques are fairly simplistic and do n’t put up much feedback on the pump ’s condition . [ 7 Cool Uses of 3D printing process in Medicine ]
" Currently , aesculapian devices to treat meat cycle diseases are fundamentally based on two electrode insert through the mineral vein and deployed inside the chambers , " study co - author Igor Efimov , a biomedical applied scientist at Washington University in St. Louis , said in a statement .
Efimov and his colleagues used aesculapian imaging to scan a rabbit heart , and then used3D printingto create a example for the heart . From there , the team create a slender silicon sheath , embedded with tiny sensing element , that fits over the outside of the nerve utterly . The squad then try out the mechanical and electrical properties of the affection " jacket " as it contract with rabbit nub .
The sensing element - filled sum arm could one Clarence Shepard Day Jr. be used to not only test forheart disease , but also to trail the wellness of other organs , such as the kidneys , the researchers say .
" Because this is implantable , it will allow for MD to monitor vital functions in unlike pipe organ and intervene when necessary to provide therapy , " Efimov say . " In the pillowcase of heart rhythm disorderliness , it could be used to stimulate cardiac muscle or the encephalon , or in [ kidney ] disorders , it would monitor ionic concentration of Ca , atomic number 19 and atomic number 11 . "
In addition , the sensors could one day measure out an enzyme called troponin , a telltale mark ofheart attacks . That could aid doctors detect heart troubles even in the beginning than current tests .
