Powerwand IV Midline Catheter Achieves 23,000 Catheter Days with Zero Bloodstream Infections

Dr Steve Bierman, MD. Chief Medical Officer, Access Scientific.


Access Scientific announced today that the POWERWAND™ midline catheter now has over 23,000 catheter days of scientific data without a single catheter-related bloodstream infection (CRBSI). This follows new data presented at the prestigious Association for Vascular Access national conference, which took place in Phoenix, AZ in late September.

Data collected at Methodist Hospitals in Indiana, representing 2,688 patient days of POWERWAND use, indicated the use of POWERWAND lead to a 35% reduction in the number of peripherally inserted central catheters (PICCs) placed.  Zero bloodstream infections were reported during the 12-month study period and 79% of patients utilized POWERWAND through their completion of therapy.

Methodist Hospitals’ data, coupled with five peer-reviewed, published studies and seven scientific posters demonstrate POWERWAND’s consistently superior performance. In addition to the zero CRBSI achievement, the accumulated studies & posters prove POWERWAND’s superior blood drawability and lowest total complication rate and highest completion of therapy rate of any midline ever studied.

POWERWAND is made of a unique catheter material (ChronoFlex C®) that, when coupled with Access Scientific’s proprietary manufacturing processes, produces a catheter capable of outperforming the competition.

“The consistently superior clinical performance of the POWERWAND is extraordinary,” remarked Steve Bierman, Access Scientific’s Founder and Chief Medical Officer. “POWERWAND’s proprietary catheter material and manufacturing processes are unparalleled. POWERWAND is the evidence-based midline of choice.”


Training and Education

Louise Freeney, Clinical Nurse Educator Vascular Access, pfm medical UK Ltd


The design and development of Powerwand® now available in 3Fr, 4Fr & 5Fr is revolutionary for Vascular Access (VA), as this is a short to mid-term answer for patients who require IV therapy including CT/MR power injection scans for up to 29 days and potentially beyond.

Training for nursing and medical staff to insert Powerwand with minimal disruptions for the patient and their quality of life is paramount and also to ensure treatment is uncomplicated in terms of cost efficiency of equipment required, eradicating catheter–related blood stream Infections (CRSBI), reducing thrombosis rates and minimising the length of time to place the device.

The clinical training, education and support the Vascular Access team offer at pfm medical UK offer is outstanding and by far the best within the industry. We provide our customers with evidence based knowledge, professionalism and reassurance that Powerwand (if used correctly) is a unique product which has proven to have a dramatic impact on patient experience, satisfaction and safety thus assisting nurses and doctors with a seamless procedure.



The Danger of Cut Catheters

Dr Steve Bierman, MD. Chief Medical Officer, Access Scientific.



Customers often ask, Why does the Powerwand XL® have so many fewer complications than the other midlines and extended-dwell catheters we have tried?  Flip that over and it sounds like: Why do other non-Powerwand midlines have so many more complications (DVTs, leaking, phlebitis, etc.) than Powerwand midlines?

The answer is really quite simple: Cut Catheters appear to cause irritation to the vessel lining (i.e, the intima), which in turn causes complications.  Watch this video which depicts the dangers of cut catheters quite well.

The Powerwand is not a cut catheter; its tip is thermoformed into an atraumatic ZERO-EDGE™ transition. Beyond that, the Powerwand guidewire has a soft, plastic domed tip.  Atraumatic Powerwand insertion leads to superior clinical outcomes.

But there is more.  The other midlines are all made of polyurethane or a polyurethane blend.  Those polyurethane midlines with published outcome data all have higher bloodstream infection rates than Powerwand.  Why?  Because the Powerwand is not polyurethane. It is made of a remarkable new polymer called ChronoFlex C®, which before becoming a Powerwand, goes through our proprietary manufacturing process.  The result: Over 20,000 catheter-days of peer-reviewed, published studies, from 5 different investigators and 6 different institutions, with ZERO bloodstream infections.

Atraumatic insertion + Thermoformed ChronoFlex C = The undisputed best-in-class, Powerwand midline and extended-dwell catheter.  There is method to the Powerwand magic.



At last, the potential for a ‘one-stick’ hospitalisation.

Dr Steve Bierman, MD. Chief Medical Officer, Access Scientific.



Our hearts go out to all the children whose childhoods are interrupted by hospitalisation. Thankfully, there is a new and simple way to lessen their suffering—a unique vascular access device that finally offers hospitalised children the true potential for a ONE-STICK hospitalisation. That wonderful addition to our vascular access toolbox is the 3Fr Paediatric Powerwand® XL.

Children’s wards and Children’s Hospitals all over the USA are celebrating the advent of this new, all-purpose Paediatric Powerwand® for its extraordinary first-attempt success rate, superb blood-drawability, extended dwell times (up to 29 days) and minimal complications. The product is soon to be released in the UK. As an accomplished pediatric vascular specialist in the Midwest recently said, “It’s so nice to have mothers actually squeezing our hands and thanking us.  One told me the Powerwand® prevented her child from getting between 40-50 needlesticks.”

The Paediatric Powerwand® is designed to reduce: (1) CLABSI, (2) Venous Thromboembolism, (3) PIVIEs (infiltrations and extravasations), (4) pressure injuries–PLUS (5) medical adhesive-related skin injuries.

The world of Paediatric vascular access just changed dramatically for the better.  The Paediatric POWERWAND—giving hospitalized children their first true shot at a ONE-STICK hospitalisation.

I am confident this new POWERWAND product will add greatly to the daily gratification of your important work.



New study proves Powerwand® safe for Vancomycin delivery.

Dr Steve Bierman, MD. Chief Medical Officer, Access Scientific.



Definitive proof has finally arrived.  PICCs are no longer required to deliver long-term or short-term vancomycin (4mg/ml). Over 1000 patients, representing over 8000 catheter-days, are reported in this month’s JAVA to have had no DVTs and no bloodstream infections and minimal phlebitis (0.6%) during intravenous vancomycin administration through the Powerwand® midline.

(Full Article)

What does this ground breaking study mean for you and your institution?

In most hospitals, vancomycin administration is an indication for about 20% of PICCs.  This new Powerwand® study demonstrates that these patients no longer need PICCs, which means you can reduce your central line days by roughly 20%. Instead of a PICC, a 4Fr or 5Fr Powerwand® placed in the deep vessels of the upper arm will get the job done safer and more cost-efficiently.

Remember, only the Powerwand® midline has over 20,000 catheter days of published data attesting to zero bloodstream infections and the lowest complication rates of any vascular access device ever studied. Couple this with the news of safe vancomycin administration (over 5 years, in over 1000 patients) and you really have compelling reasons to support your Powerwand® use.

It’s a pleasure to share this information with you, because it means that everyone—patients and providers—gets to share the benefits Powerwand® use.  Thank you for your continued, evidence-based support.



Finally, a solution for Hard Stick Patients.

Dr Steve Bierman, MD. Chief Medical Officer, Access Scientific.


I often travel to hospitals all over the country and hear stories from clinicians who are frustrated by peripheral IVs that don’t last. Think about your own practice – how often does it happen that you are called to start a peripheral IV on a hard stick patient only to have to restart it the next day?

Did you know that the median dwell time for an ultrasound-guided PIV is only 26 hours?  All the skill, time and effort you and your colleagues apply to the placement of these vital lines, unfortunately, results in an IV that lasts barely more than a day.  Why?  Because PIVs are simply too short (and too easily kinked) to function for any substantial time in the deeper veins of the arm and forearm.

Fortunately, there is a solution: The first true extended dwell catheter designed to extend the life of ultrasound guided peripheral IVs up to 29 days – The new Powerwand® EDC–3French, 6 cm (2.4 inches).

The new 3Fr, 6 cm Powerwand® is longer than a PIV, capable of power-injection up to 8 mL/sec, and is designed for the same reliable blood-drawability and extended dwell times as the Powerwand® midlines.  Made of ChronoFlex™C, this new tool in your toolbox, is ideal for renal patients, and vein preservation, in general; ultrasound guided PIVs, patient’s requiring extended treatment but who do not need the hemodilution afforded by the Powerwand® midlines.

Please consider this next great innovation from Access Scientific and available from pfm medical UK – The Powerwand® 3Fr, 6cm Extended Dwell Catheter.  Your patients will thank you.
