uCompare uCompare Anatomy Based Hospital Ratings
We know that choosing a hospital is hard. So uCompare is employing an interactive Decision Assistant to help customers, er, patients, in selecting the best hospitals for them.

…if you are researching hospitals for a heart-related procedure you might be interested in learning how many coronary bypass procedures each performed, the patient mortality rate, the average length of stay and overall costs-and how this compared to other hospitals, and to the national average.

The Decision Assistant makes it easy: If you want to know what criteria are involved in rating hospitals on knee surgery, you click on the illustrated woman’s knees. Breast surgery? NSFW. You can also rotate the model, and change its gender (the male version is somewhat lacking).
Let’s hope they don’t adapt this interface for patients to select their doctors…

transmedics Transmedics: Better Transport for Transplants
It’s been a staple of medical dramas and third-year student rotations for years: transporting organs on ice. But Transmedics is moving forward with clinical trials that may prove their system is superior:

Since the advent of transplantation, the cornerstone of organ preservation has been cold ischemic storage. Although this method was intended to help reduce the extent of organ damage during transport, significant damage still occurs. The more time that passes, the more damage occurs.
Living organ transplant performed with the TransMedics Organ Care System could resolve many of the limitations associated with cold ischemic storage. By pumping warm, oxygenated, nutrient-rich blood through the organ from the time of removal until it is implanted, the organ may withstand longer periods of time outside of the body and be less vulnerable to damage during transportation to the recipient. More extensive testing for function and tissue matching may also be possible with a functioning organ.

They keep the donated organs going by pumping donor blood through the tissue, along with their own nutrient mix. Not only do they keep hearts beating, but we even saw defibrillator pads in the heart container!
We’re not sure the system will “remove urgency” from the transplant process, like they claim, but it would be great if they improve organ viability and uptake.

wickedlaser She Blinded Me With Science
We’ve been afraid to blog about the Wicked Lasers, which look a lot like normal presentation-style pointers but can burn a hole through the screen and the eyes of audience members. But despite the obvious potential for harm, and the FDA warnings and fines, these lasers are, after all, medgadgets:

The medical use of class IIIb lasers has long been licensed and practiced. Although Wicked Lasers products have not been specifically approved for medical use, at least one medical professional has been experimenting with our lasers in the US. A practicing chiropractor since 1977, he prefers that we not use his name in association with use of a laser that has not yet been licensed for medical use.

Well, that settles that. The site goes on to explain that lasers are good for healing sprains and cauterizing wounds. Oddly enough, the video gallery doesn’t show any medicinal uses! Instead they feature footage of lasers lighting matches, cutting plastic, and popping balloons.
Gizmodo is giving away a wicked laser to the person who makes the best MP3 of an alien invasion (?).
We are countering their offer: Medgadget editors will give free medical and legal advice to the winner, after he or she injures someone / brings down an airliner / creates an international incident, in exchange for said laser.
Why do we want such powerful laser? We have some clinical trials planned, of course.

Minnesota, home of medical device companies like Restore Medical (see below) and mighty Medtronic, may become a little more hostile to these innovative firms. Instead of just supplying a free replacement, the companies may have to pay for the surgery and medical fees, as well.
The aptly-named Pioneer Press has the story:

In an effort to get medical-device manufacturers to pay “for their mistakes,” a lawmaker introduced a bill at the Capitol on Monday that would require the companies to cover medical costs when their devices are replaced because of a recall.
While med-tech companies provide a free replacement device, it is the patient’s insurance that typically pays for the surgery and related costs…
…A constituent who has gone through several recalls since receiving a Medtronic implantable defibrillator in 1999 spurred Cornish to propose the legislation.
Sue Peterson, a 49-year-old registered nurse from Lake Crystal, said she didn’t think it was fair that her insurance company covered the costs, and she is worried that she eventually could exceed her insurance policy’s $1 million maximum.
“I wanted them (Medtronic) to replace and pay for the medical costs,” Peterson said

Since this isn’t being enacted at the federal level, we wonder if the proposed bill might have the unintended consequence of making implants tougher to obtain in Minnesota (or if the companies will be tempted to move someplace… warmer).

inserts mouth Fewer Obstructions for Pillar System
It’s been over a year since we covered the Pillar System for obstructive sleep apnea. But the company that makes the device, Restore Medical, continues moving forward, having filed for an IPO this year.

The Pillar system is a minimally invasive, implantable medical device to treat sleep-disordered breathing, which includes OSA and snoring. During the procedure a physician implants three small, braided polyester inserts into the muscle of the soft palate to stiffen it. This minimizes or eliminates the palatal tissue vibration that can cause snoring and the collapse that can obstruct the upper airway and cause OSA. Restore got FDA clearance for the treatment for snoring in December 2002 and OSA in July 2004.
The filing says more than 1,000 physicians have performed 11,000 Pillar procedures, with U.S. patients paying an average of $1,200 to $2,500.

Since one in five adults may suffer from OSA, and since the procedure looks pretty simple (at least on the company’s animated flash), Restore Medical could be poised for big things. Definitely one to watch.

Grevesm A Site for Sore Eyes
We just don’t hear too many operatic songs about diseases anymore.
So were were giddy when GeekNurse pointed us to the Glaucoma Hymn, written especially for the Association of International Glaucoma Societies, performed by soprano Melanie Greve.
Not since Foreigner’s “Double Vision” have we heard such a stirring song about ophthalmological issues.
Can the Medgadget Hymn be far behind?

6662376 Nanotech Used to Restore Vision After TraumaFor the first time ever, scientists were able to use nanotechnology to repair a damaged brain and restore vision. Work done by MIT investigators in a rodent model is being reported in the early online edition of the Proceedings of the National Academy of Sciences:

In the experiment on young and adult hamsters with severed neural pathways, the researchers injected the animals’ brains with a clear solution containing a self-assembling material made of fragments of proteins, the building blocks of the human body. These protein fragments are called peptides.
Shuguang Zhang, associate director of the CBE and one of the study’s co-authors, has been working on self-assembling peptides for a variety of applications since he discovered them by accident in 1991. Zhang found that placing certain peptides in a salt solution causes them to assemble into thin sheets of 99 percent water and 1 percent peptides. These sheets form a mesh or scaffold of tiny interwoven fibers. Neurons are able to grow through the nanofiber mesh, which is similar to that which normally exists in the extracellular space that holds tissues together.
The process does not involve growing new neurons, but creates an environment conducive for existing cells to regrow their long branchlike projections called axons, through which neurons form synaptic connections to communicate with other neurons. These projections were able to bridge the gap created when the neural pathway was cut and restore enough communication among cells to give the animals back useful vision within around six weeks. The researchers were surprised to find that adult brains responded as robustly as the younger animals’ brains, which typically are more adaptable.
“Our designed self-assembling peptide nanofiber scaffold created a good environment not only for axons to regenerate through the site of an acute injury but also to knit the brain tissue together,” said Zhang. The technique may be useful for helping close cuts in the brain made during surgery to remove tumors.

Dr Lauren Stewart, professor at University College London, is running an online experiment that tries to identify people suffering from congenital amusia, or tone deafness.
Dr. Stewart explains:

“People with this condition are literally tone deaf – not in the sense of being unable to sing in tune – but in the sense that they cannot recognise familiar tunes or tell two tunes apart. They often find listening to music unpleasant – for instance one lady described Rachmaninov’s second piano concerto as ‘banging that would be best avoided’.”
