Rush begins use of magnetic guided navigation system

12.12.2002


Rush is first site in the Chicago area to obtain the stereotaxis technology and one of only two in the world with an emphasis on neurosurgical applications



Neurosurgeons at Rush-Presbyterian-St. Luke’s Medical Center have become the first in the Chicago area to use a radically new, magnetically controlled system to enter the brain and its vascular system to treat a variety of diseases without surgically opening up the skull and brain.

"Magnet-guided neurosurgery allows us to use a guidewire and catheter to manipulate surgical tools within the brain in ways that previously were impossible," said Dr. Leonard Cerullo, chairman of the department of Neurosurgery at Rush and founder, president and medical director of the Chicago Institute of Neurosurgery and Neuroresearch (CINN) medical group.


"Because we can enter the brain through a blood vessel that is accessed through a small incision in the upper thigh, we have the potential to substantially reduce the need to surgically open the skull and disrupt brain tissue in order to repair aneurysms and deliver stroke therapies. We hope this will result in more effective treatment, reduced costs and swifter recovery times," he noted.

The first patient, a 48-year-old man from Chicago, was successfully treated with the technology on Tuesday, December 10. He suffered from headaches and double vision caused by malformed blood vessels in the back of his head. Swelling of the blood vessels put pressure on the brain and caused the double vision.

The system uses a magnetic field, controlled by the physician using point and click devices, to deflect the tip of a specially designed guidewire or catheter that is mechanically pushed or pulled through the body. Unlike existing guidewires and catheters, the new guidewires and catheters can be advanced through a vessel as small as one millimeter and are designed to be flexible enough to make a turn angle sharper than 90 degrees.

Initially, neurosurgeons at Rush will use the system in a clinical trial to access clogged vessels in the brains of newly diagnosed stroke patients. They also plan clinical research protocols to treat brain aneurysms and tumors.

"Our clinical research should lead to new ways to treat brain aneurysms by directing a catheter into the aneurysm, holding it in place, and then injecting a special material to obliterate it," said Dr. Demetrius Lopes, CINN’s neuroendovascular specialist who will be the principal neurosurgeon using the technology.

In the spine, the catheter’s flexibility is expected to enable neurosurgeons to navigate multiple nerve routes with one needle-stick entry point instead of the current procedure that requires one-needle stick entry point per nerve route, which is a painful and time-consuming process.

The technology is also expected to advance Rush’s research efforts in restorative neurosurgery to treat movement disorders (Parkinson’s disease, epilepsy), pain syndromes and mental illnesses. This will potentially involve using the magnetic navigation technology to accurately place tiny electrodes, stimulators or recording devices into the brain to modify the brain’s electrical signals in order to modify behavior, alter the natural history of certain diseases or to deliver therapeutic agents to specific areas of the brain. Currently, neurosurgeons must enter the brain through a hole in the skull and manually push a rigid needle in a straight-line route through any brain tissue on its way to the target area.

Interventional cardiologists at Rush will also use the system to participate in trials intended to dramatically expand the ability of cardiologists to open up vessels supplying blood to the heart. "Many blockages, due to their severity or location, currently can only be treated using drugs or cardiac bypass surgery," said cardiologist Dr. Gary Schaer, director of the Cardiac Catheterization Laboratories at Rush.

Rush recently invested more than $2 million in facilities and to acquire the Telstar interventional workstation manufactured by Stereotaxis, Inc., of St. Louis. The technology combines computer-controlled magnets, a flexible catheterization system and an X-ray fluoroscope that permits surgeons to view organs and medical devices in the body. The Food and Drug Administration has approved the system for use in clinical trials to test new ways to navigate guidewires and catheters within the heart and brain.

Rush is only the third site in the country to obtain the technology. Other centers with the magnetic navigation technology are Washington University in St. Louis and the University of Oklahoma in Oklahoma City, Okla.

Patients from all of CINNs seven offices will be able to be treated at the new Rush facility. CINN is the largest neurosurgical group practice in the Midwest. All of the 22 CINN neurosurgeons are on the faculty of Rush Medical College.

Im Focus: Can the immune system be boosted against Staphylococcus aureus by delivery of messenger RNA?

Staphylococcus aureus is a feared pathogen (MRSA, multi-resistant S. aureus) due to frequent resistances against many antibiotics, especially in hospital infections. Researchers at the Paul-Ehrlich-Institut have identified immunological processes that prevent a successful immune response directed against the pathogenic agent. The delivery of bacterial proteins with RNA adjuvant or messenger RNA (mRNA) into immune cells allows the re-direction of the immune response towards an active defense against S. aureus. This could be of significant importance for the development of an effective vaccine. PLOS Pathogens has published these research results online on 25 May 2017.

Staphylococcus aureus (S. aureus) is a bacterium that colonizes by far more than half of the skin and the mucosa of adults, usually without causing infections....

Im Focus: Turmoil in sluggish electrons’ existence

An international team of physicists has monitored the scattering behaviour of electrons in a non-conducting material in real-time. Their insights could be beneficial for radiotherapy.

We can refer to electrons in non-conducting materials as ‘sluggish’. Typically, they remain fixed in a location, deep inside an atomic composite. It is hence...

Im Focus: Wafer-thin Magnetic Materials Developed for Future Quantum Technologies

Two-dimensional magnetic structures are regarded as a promising material for new types of data storage, since the magnetic properties of individual molecular building blocks can be investigated and modified. For the first time, researchers have now produced a wafer-thin ferrimagnet, in which molecules with different magnetic centers arrange themselves on a gold surface to form a checkerboard pattern. Scientists at the Swiss Nanoscience Institute at the University of Basel and the Paul Scherrer Institute published their findings in the journal Nature Communications.

Ferrimagnets are composed of two centers which are magnetized at different strengths and point in opposing directions. Two-dimensional, quasi-flat ferrimagnets...
