Harvard Develops Drug-Filled, Injectable Sponge That Expands Inside the Body

An anonymous reader writes "Harvard bioengineers have perfected injecting us with a drug-filled sponge instead of just a liquid. It may seem strange to want to inject a piece of sponge into your body, but it does actually help solve a number of invasive problems. For example, sometimes it is necessary to have drugs released slowly into our bodies, and/or some kind of bio-scaffold is required to be positioned so that it can help support a damaged organ or to engineer new tissue. This new, injectable sponge is incredibly useful because not only can it be filled with drugs that then are slowly released, it also has a memory and can be collapsed down to a tiny fraction of its original size."

I guess doctors will have to decide...

Custom shapes

My favorite part of the article is the picture of custom sponge shapes. Can I get my insulin sponge-shot shaped like a Lucky Charms marshmallow? http://www.geek.com/wp-content/uploads/2012/11/cryogel_sponge_02.gif [geek.com]

So, in a few years time when my body slumps a little more and my ass is hanging down, I can get a 'Sponge Bob' job down the back and another complementary do-hickey up front? This is strangely appealing on several levels. I can see the cost benefit analysis, and why wait for the future; do they need human test subjects?

As long as it results in square pants, I fully support your sponge bobbing.

If they inject this into the blood stream, definitely. But they're probably putting it into connective tissue, so that the drug can diffuse into the blood while the sponge stays and degrades.

The original press release [harvard.edu] (linked in TFA) says the following:

"The simplest application is when you want bulking," Mooney explains. "If you want to introduce some material into the body to replace tissue that's been lost or that is deficient, this would be ideal. In other situations, you could use it to transplant stem cells if you're trying to promote tissue regeneration, or you might want to transplant immune cells, if you're looking at immunotherapy."

Makes me wonder what other kind of sponges are out there that can't hold liquid, can't collapse, and don't remember their shape. O_o

How is this new?

[morganjayp]

Um, Harvard invented the twinkie?

Memory?

This new, injectable sponge ... has a memory and can be collapsed down to a tiny fraction of its original size.

So does my kitchen sponge.
