Medtronic launches POWEREASE Instruments for Reconstructive Spine Surgery

In a News Release Medtronic announces the launch of the POWEREASE System, a system of electronic instruments designed specifically for the use in instrumented, or reconstructive, spine surgery.

The POWEREASE System is used for drilling, tapping and driving specialized implants during spinal surgery, including open and minimally invasive procedures.

According to the News Release, biomechanical testing versus manual instruments demonstrated that the POWEREASE™ System required 51% less time for tapping the pedicle and 55% less time for placing pedicle screws. This testing also showed greater control with 38% less wobble of the instrument compared to manual instruments. However, biomechanics testing is not necessarily indicative of human clinical outcome.

MRI Atlas of Human White Matter for iPads

Elsevier has released its NeuroApps: MRI Atlas of Human White Matter, an interactive app for the Apple iPad.

 

The app includes:

  • Two types of stereotaxic coordinates (Talairach and MNI coordinates) are provided to define brain locations.
  • Includes both MRI and DTI images and allows the user to switch between MRI and DTI view for any location in the brain
  • Fifty three white matter structures, 38 cortical areas, and 22 deep gray matter structures are defined and labeled. In addition, locations of 11 white matter tracts and 36 cytoarchitectonic areas are defined. These structures can be interactively superimposed on the MRI/DTI images.
  • The trajectories of the tracts can be followed sequentially through the brain.

Aquamantys SBS 5.0 Sheathed Bipolar Sealer receives FDA clearance

 

Medtronic has announced that their Aquamantys SBS 5.0 Sheathed Bipolar Sealer for spine surgery has received 510(k) clearance from the Food and Drug Administration (FDA). The device is developed for sealing soft tissue and epidural veins during spinal surgery. The device delivers RF energy for cauterization and saline to keep the area clean and clear for easy access around sensitive tissue.

 

“The SBS 5.0 is a great combination tool that will allow surgeons to treat cut muscle planes as well as compress and treat epidural veins with a single device,” said Dr. Paul Santiago, a surgeon at Washington University School of Medicine. “This will be particularly useful in cases like 1-2 level TLIFs/PLIFs in which you want the ability to address both of these needs but the economics can make using multiple devices difficult.”

InfrascannerHand-held device looking for intracranial hematomas receives FDA approval


In a News Release FDA announce that they permits marketing of the first hand-held device to aid in the detection of bleeding in the skull.


The Infrascanner, Model 1000, uses a scanner that directs near-infrared light, a wavelength of light that can penetrate tissue and bone, into the skull. Blood from intracranial hematomas absorbs the light differently than other areas of the brain. The scanner detects differences in light absorption (optical density) and transmits the information wirelessly to a display on a hand-held computer.By comparing the optical density from a series of scans of specific areas on both sides of the skull, a trained health care provider can use the information provided by the device, in conjunction with other clinical information, to determine the likelihood of an intracranial hematoma and the need for further diagnostic procedures, such as a computed tomography (CT) scan.


The FDA granted the de novo petition for the Infrascanner Model 1000 based on a review of data comparing results from 383 CT scans of adult subjects with Infrascanner scan results. The Infrascanner was able to detect nearly 75 percent of the hematomas detected by CT scan. When CT scans detected no hematoma, the Infrascanner detected no hematoma 82 percent of the time. A number of papers have shown even higher sensitivity and specificity (Robertson et al., 2010; Leon-Carrion, 2010). The device, which already has a CE Mark, is, however, not a substitute for a CT scan.

CertasNew CODMAN CERTAS programmable valve

 

In a Press Release Codman announces the launch of a new shunt valve - the CODMAN CERTAS Programmable Valve.

 

The CODMAN® CERTAS Programmable Valve has eight settings to control the rate of drainage of CSF from the brain to the abdomen, virtual off to test shunt independence, and resistant to MRI influence up to 3 Tesla (Codman recommends that the clinician confirm the valve setting after MRI).
