VertexOccipitocervical Spinal Reconstruction System

In a News Release Medtronic announced the U.S. launch of the VERTEX SELECT® Reconstruction System.

According to the News Release: When a patient has a spinal condition that requires fusion or a procedure that must be performed from the back of the spine, also known as a posterior approach, the VERTEX SELECT® Reconstruction System contains implants and an instrument set for performing this surgical procedure.

Conditions of the spine, such as degenerative disc disease, tumor, or trauma, can lead to instability and pain for patients. To treat the instability, surgeons perform a spinal fusion, which involves joining two or more vertebrae together.

SyngoNeuro PBV IR Monitors Intracranial Parenchymal Blood Flows

Siemens reports about new functional imaging for interventional neuroradiology - syngo Neuro PBV IR.

Syngo Neuro PBV IR (Parenchymal Blood Volume, Interventional Suite) is a new application for interventional radiology that allows you to review parenchymal blood flow during minimally invasive interventions in the brain for the first time.

This feature assists the neuroradiologist in the treatment of stroke patients by displaying the condition of the cerebral tissue directly in the angio suite.

marled_.jpgNew generation of operating lights

A Press Release from KLS Martin Group describes their operating lights - marLED® V16 and V10, have been successfully validated in conjunction with the integrated OR1 operating room systems manufactured by Karl Storz GmbH & Co. KG. The “Universal OR” interface of the SCB module from Karl Storz enables users to control up to 4 marLED® light heads conveniently by touch screen.

The following light functions can be controlled: ON/OFF, light field diameter, color temperature, and dimming. The surgiCam® SD and HD camera systems have also been validated for operation with the OR1 system. With its latest release, the OR1 system is capable of generating a complete image of the camera operating functions.

IMRISMRI Fluoroscopy Systems for Intraprocedural Multimodal Imaging

In a Press Release IMRIS Inc announces the FDA clearance of IMRISnv, a system with both MRI and x-ray angiography in a single suite.

The IMRISNV features a 3T MRI scanner and a bi-plane angiography system completely integrated into a single suite that permits the patient to transition quickly and seamlessly between MR imaging and intervention without transporting the patient. Using IMRISNV, MR images can be taken before and during procedures to assess tissue health, and can also be used in conjunction with the fluoroscopic images during the interventional procedure.

SovereignNew spinal system for lumbar surgery

According to a News Release Medtronic introduces a new spinal system for lumbar surgery - SOVEREIGN. The system is designed to to stabilize the spine and promote bony fusion.

The SOVEREIGN is indicated for use with autogenous bone graft in patients with degenerative disc disease at one or two contiguous vertebral levels from L2 to S1.

The SOVEREIGN intervertebral body fusion device may be used as a stand-alone device or in conjunction with supplemental fixation.

NexstimAssessment of the primary motor cortex

Nexstim (Helsinki, Finland) reports that FDA has given approval for their Navigated Brain Stimulation System for the assessment of the primary motor cortex for pre-procedural planning.

Using transcranial magnetic stimulation (TMS) guided by standard MR-image data, Nexstim's Navigated Brian Stimulation (NBS) offers a non-invasive direct technique for functional mapping of the motor cortex. In its FDA submission, Nexstim included data comparing the accuracy of NBS pre-operative mapping with the results of "gold standard" direct cortical stimulation during actual brain tumor surgery.

DBSDBS and epilepsy

In a News release from Medtronic, data is presented from the investigational study SANTE® (Stimulation of the Anterior Nucleus of the Thalamus in Epilepsy).

The aim of SANTE® is to study Deep Brain Stimulation (DBS) Therapy for Epilepsy. The results of the study show improvement over time with median reduction in seizure frequency of 41 percent at one year, 56 percent at two years, and 68 percent at three years of DBS therapy.

Of the original 110 patients who received DBS implants in the trial, 91 remain active in the study. At the time of this data analysis, 102 patients had completed two years and 57 had completed three years of therapy. In addition, 14 patients (13 percent) experienced seizure free intervals ranging from six months to more than four years.

PentaFirst Five-Column Neurostimulation for Spinal Cord Stimulation

St Jude Medical has announced FDA approval for the new Penta(TM) surgical lead - featuring the smallest electrodes on the market arranged in five columns. The lead is used for spinal cord stimulation managing chronic pain of the trunk, limbs and back.

According to the press release, the new surgical lead can more specifically focus current over a greater lateral area of the spinal cord. 

It offers the broadest lateral electrode span of the neurostimulation leads on the market and the paddle configuration is 10.9 mm wide.

DuraSeal2.jpgFDA approval of DuraSeal Spine Sealant

Covidien announces that it obtained FDA approval for the DuraSeal™ Spine Sealant, which is a synthetic hydrogel for intra-operative sealing of the dural membrane during spine procedures.

Covidien refers to a prospective, multi-center, randomized controlled study by Wright et al presented at the Congress of Neurological Surgeons meeting 2009. 158 patients undergoing spinal surgery were divided in 2 groups – 102 patients received DuraSeal Sealant and 56 received standard care. Patients treated with DuraSeal had higher rate of watertight closure with initial treatment.

However, no significant difference was seen in post-operative fluid leaks or infection.

AANS2010iPod.jpgAANS meeting in Philadelphia 2010 will be paperless

At the AANS (American Association of Neurological Surgeons) meeting in Philadelphia May 2010 all content will be delivered and accessible by the iPod touch®, Apple's wireless mobile platform.

The AANS member registrants will be given an iPod touch® device at this meeting. Using the iPod they will be able to access program guides, calendars of events, exhibitor listings, speaker information, and social venues. Using the device will also allow visitors to see at a glance what events are occurring at any given moment during the meeting, interact in real time with speakers and panelists using its audience response capabilities, communicate with other attendees, access convention hall maps and exhibitor hall directories.

The iPod will also increase the interaction with exhibitors - the visitors will be able to view company websites, watch videos that illustrate a particular vendor’s product lines and meeting specials.

CobbMeter.jpgA French ortopedic surgeon, Frederic P Jacquot, has developed CobbMeter, an application which turns the iPhone into a professional measuring tool.

It is designed to measure the Cobb angle, the kyphosis angel, and the sacral slope on vertical spine radiographs.

All that one has to do in using the device is align the side of the iPhone to the standard tracings we use routinely, and the position sensor built in the iPhone will do the rest.

The precision of the device itself is 1/10th of a degree

Measures are logged for further use and may be sent by e-mail to the surgeon or staff for recording purposes, with the levels of the measured curve, type of curve and patient id or number. A calibration procedure was also implemented to accurately measure the angle with the horizontal plane as in the sacral slope.
