Abbott Supera Stent for Peripheral Artery Disease Stays Flexible for a Comfy Fit (VIDEO)

Abbott Supera stent Abbott Supera Stent for Peripheral Artery Disease Stays Flexible for a Comfy Fit (VIDEO)

Abbott received FDA approval for its Supera Peripheral Stent System for treating occluded superficial femoral and proximal popliteal arteries of the legs. The nitinol stent was developed to “mimic rather than resist” the movement of the arteries, being flexible while keeping the lumen open during physical activity and resisting kinks.

Here’s more from the announcement:

“Doctors are increasingly identifying peripheral artery disease as a major cause of leg pain, which can limit people’s ability to live a healthy lifestyle,” said Kenneth Rosenfield, M.D., section head of Vascular Medicine and Intervention at Massachusetts General Hospital and the principal investigator of the SUPERB clinical trial, which evaluated the Supera stent. “Treatment with the Supera stent, as shown by the results of the SUPERB study, is very effective in easing leg pain, enabling the majority of patients to resume their activities.”

Data from the SUPERB clinical trial, which was used to support FDA approval of the Supera stent, have shown the Supera stent to be highly effective in opening up blocked blood vessels in the upper leg, even in difficult cases, and results have been shown to last over time.2 In addition, during the first year after treatment with the Supera stent there were no stent fractures, and at two years there was a very low stent fracture rate of 0.5 percent.2 Stent fractures are a known risk of treatment with traditional metallic stents in the leg due to the frequency and type of movement in this part of the body.

Toshiba’s CT Myocardial Perfusion Imaging Technology FDA Cleared

Toshiba's CT Myocardial Perfusion Imaging Technology FDA Cleared

Toshiba received FDA clearance to introduce its CT Myocardial Perfusion technology, now being made available on the company’s flagship CT scanners, the Aquilion ONE and Aquilion ONE ViSION Edition.

CT Myocardial Perfusion allows the diagnosis of myocardial ischemia by visualizing the flow of blood within the coronary vasculature. Toshiba will be showing off the new package on its 320-detector-row CT scanners at the American College of Cardiology (ACC) annual meeting in Washington, D.C. later this month.

Somatom Scope, a Budget-Friendly CT, Helps Reduce Operating Costs

Somatom Scope, a Budget-Friendly CT, Helps Reduce Operating Costs

Siemens has released a new general purpose CT scanner, the SOMATOM Scope. The tomograph is available as an entry level, low cost of operation device, or as a more capable version, the Somatom Scope Power. The scanner takes only eight square meters (86 sq feet) of floor space, significantly reduces its energy usage over previous models, and doesn’t run as hot to save on facility cooling costs.

The system features a sleep mode that helps save energy when not in use, and the eStart function makes sure the X-ray tube is warmed up before running the first scan after the scanner takes a nap. This extends the tube’s lifetime, helping save on the costs of running the device in the long term.

BIOTRONIK Sentus ProMRI, World’s Smallest MR Conditional Leads CE Marked

BIOTRONIK Sentus ProMRI, World's Smallest MR Conditional Leads CE Marked

BIOTRONIK recently received the European CE Mark and is now releasing its Sentus ProMRI bipolar cardiac resynchronization therapy (CRT) leads. With a diameter of only 1.6 mm, these are the narrowest MR compatible leads available.

Since people on cardiac resynchronization therapy typically have other conditions, keeping open the option of MR imaging can be critical to their continued healthcare. MR compatibility coupled with the narrowness of the new leads should help improve the benefits of cardiac resynchronization for a lot of patients.

Cordis RENLANE Renal Denervation Cleared in Europe

Cordis RENLANE Renal Denervation Cleared in Europe

Cordis, a unit of J&J, received European CE Mark approval for its RENLANE renal denervation system for treatment of blood pressure in patients for whom traditional therapy is not effective. The catheter is powered by an external multi-channel RF generator and features five irrigated electrodes through which energy is delivered to denervate renal arteries that are participants in controlling blood pressure.

The company already announced initial procedures using the device at the University of Cologne Hospital in Germany to treat patients with a systolic blood pressure over 160 mm Hg. The patients were discharged after a day at the hospital and we’re very curious, considering Medtronic’s recent failure with their own renal denervation system, to see what the long term impact of this therapy is on patients.

Eonis 24 Clinical Display Guarantees Consistent Images Across Hospital

Eonis 24 Clinical Display Guarantees Consistent Images Across Hospital

Barco is releasing a new clinical monitor, the Eonis 24, for use both in semi-sterile settings and generally by clinicians around the hospital. The white model of the display is designed for thorough cleaning, having a toughened front panel and being compatible with 70% alcohol cleaning agents. The black model is intended for office use and image review when cleanliness isn’t a top priority.

The Eonis 24 with a 1920 x 1200 resolution is designed for consistent display of images across the clinical facility, so that doctors and nurses sharing images will see them identically whether looking at them in the OR or later on a different Eonis back in the office. This is accomplished with a front sensor that analyzes the image and adjusts the monitor to be in tune with facility-wide image standards.
