SAFER SPINE SURGERY?

Can we make spine surgery even safer? Preliminary data from a postmarketing study of SpineVision��s PediGuard� device suggest there is a very strong clinical trend that using PediGuard makes spine surgery safer�not only for patients but for surgeons too.PediGuard is the first and only FDA-cleared Class II device for real-time detection of possible penetration outside the vertebral pedicle. Accuracy of pedicle screw placement is still an issue in spine surgery: published rates of intraoperative...

DNA VACCINES

Researchers at the Centers for Disease Control and Prevention reported in the November 2007 issue of JAMA that conventional vaccines have cut disease deaths by 99%, but have been limited to only 13 disease targets. DNA vaccines, on the other hand, have been touted as some day preventing or curing cancer, AIDS and a litany of other infectious diseases. But the promise of DNA vaccines has been thwarted by a lack of an effective delivery vehicle. In fact, delivering DNA vaccine inside targeted c...

HOSPITAL-ACQUIRED INFECTIONS

In the United States, attempts to control hospital-acquired (�nosocomial�) infections are proving ineffective, according to the Government Accountability Office (GAO). In fact, hospital-acquired infections are estimated to be one of the top-ten causes of death in the U.S., claiming 90,000 lives every year. In this episode, we look at how Dijon Hospital in Dijon, France, is protecting its most vulnerable patients with a new mobile infection control technology from AirInSpace. The company�s de...

VANISHING STENTS - PART 2

What if there were a stent that could promote natural remodeling of an injured artery after angioplasty, and then just disappear?�"Just three years ago bioresorbable stents seemed to be more of a nice to have than a need to have.� After all, drug-eluting stents (DES) were seen as the answer to restenosis and showed very minimal risks to patient safety. Johnson & Johnson and Boston Scientific had the clear lead in introducing Cypher and Taxus, respectively, to the interventional community, wi...

NANOMEDICINE AND TARGETED CANCER THERAPY SERIES

One in four deaths in the U.S. is from cancer, making it the second-leading cause of death after heart attack. �Radiation therapy�also called radiotherapy, x-ray, or irradiation�is typically used to kill cancer cells and shrink tumors. Radiation therapy injures or destroys cells in the area being treated by damaging their genetic material, making it impossible for these cells to continue to grow and divide. The goal of radiation therapy is to damage as many cancer cells as possible, while limiti...

NANOMEDICINE AND TARGETEDCANCER THERAPY SERIES

More than half of all cancer patients worldwide receive radiation therapy�also called radiotherapy, x-ray, or irradiation�to treat their disease. According to the American Cancer Society (ACS), there were 12 million new cases of cancer worldwide in 2007. By 2050, ACS estimates there will be 27 million new cases worldwide on an annual basis. Radiation therapy is typically used to kill cancer cells and shrink tumors. Radiation therapy injures or destroys cells in the area being treated by damagi...

Heart FailureIntervention

Sunshine Heart is a medical device company focused on commercializing C-Pulse��an implantable, non-blood-contacting heart assist therapy for treating people with moderate heart failure: a condition in which the heart progressively loses its ability to efficiently pump blood throughout the body. C-Pulse reduces the symptoms of heart failure through the use of counterpulsation technology, which enables an increase in cardiac output and coronary blood flow and a reduction in the heart�s pumping wo...

All Stem Cell ConcentrationsAre Not Created Equal

There has been considerable excitement generated concerning the potential of bone marrow cells to be effective in regenerating damaged tissue; however, it is important to demonstrate that the method for isolating these cells does not impair their regenerative potential. It is for this reason that Harvest Technologies contacted Professor Doctor Christopher Heeschen at the Ludwig-Maximilians University in Munich GERMANY to evaluate its BMAC cellular composition against the gold standard.Professor...

Unclogging the Forks

A bifurcation is an area where one main blood vessel branches out into two smaller vessels, like a fork in the road: one being the continuation of the main vessel, the other one often referred to as the side branch. Narrowings at a bifurcation are very common�more than 500,000 bifurcation coronary lesions are treated each year. But even using drug-eluting stents (DES), the restenosis rate in bifurcations is a startling 23-26 percent. The difficulty in treating bifurcated lesions with convention...
