Bolivian Knitters Help Heal Hearts

The indigenous Aymara women of Bolivia have knitting as part of their heritage, but now they are able to use old skills in a new way by helping make medical devices to save the lives of children born with holes in their hearts.

The device, known as Nit Occlud, was designed by Franz Freudenthal, a cardiologist in La Paz. It looks like a little top hat knit out of wire and can be made in different sizes to block a hole in the heart.

It’s made of nitinol, a nickel-titanium alloy, and can be collapsed and inserted into the body through a catheter. It’s only expanded when it gets where it needs to go, making the procedure minimally invasive and inexpensive, which is a must in Bolivia, the poorest nation in South America and a place without enough cardiac doctors to treat kids with heart problems, which can also be more serious in the high altitudes.

It takes about two hours working in a clean room to knit a device, and knitter Daniela Mendoza told the BBC she’s glad to be able to help.

“We are very happy, we are doing something for someone so they can live,” she said.

Sometimes I feel like knitters get intimidated to try new things because they think they need to start with a big project. Your first time working in the round doesn’t need to be a sock, and your first colorwork doesn’t need to be a sweater, for example. You can find little projects that use the skills you want to learn to build your confidence before you move on to something that requires more time commitment.

This adorable knit bunny, for example.

The colorwork bunny from Knit Picks was designed by Amy Munson and is a kind of bowling pin shaped bunny complete with a knit hat, contrasting inner ears and a little stranded colorwork on its body. Note that the ears are attached the the hat not the bunny, but you could stitch them to the bunny if you’d rather.

It’s worked from the bottom up and also has a tiny pompom tail you can’t see in the picture but it’s a really cute touch. There are a variety of little fair isle patterns to choose from to make the best bunny for you.

The bunny comes out about 8 inches tall (or just over 20 cm) and use several colors to complete the colorwork, depending on the design you choose.

You can purchase the pattern by itself from Knit Picks, or make a kit that includes sport weight yarn in all the colors you need for your creation. There are gray and brown options for the main body of the bunny, but of course if you’re using your own yarn you can make it whatever color you like.

Once you’ve tried colorwork (maybe also working in the round and shaping if those are skills you haven’t used before) in a little project like this you’ll be ready to take on something bigger in no time.
