Designed to Prevent Formation of Biofilm on Catheters

Indwelling urinary catheters are a common device used by clinicians to resolve urinary retention problems. Regardless of the material the catheter is made of, bacteria will adhere to its surface and within a short period of time will colonize to form a biofilm that will contaminate the catheter surface. This biofilm dramatically increases the risk of the patient acquiring a Catheter Associated Urinary Tract Infection (CAUTI). UroShield is a disposable ultrasound device designed to reduce biofilm, this is accomplished by generating and propagating low frequency low intensity ultrasonic energy throughout the catheter.
Ultrasound interferes with the bacteria’s touch sensors discouraging bacterial docking on the catheter and leading to reduction of bacterial colonization and biofilm, thereby reducing risk of CAUTI. UroShield can be attached to any indwelling urinary catheter transforming it into a therapeutic device that has the ability to reduce urinary tract infections and potentially to alleviate spasms, related pain and inconvenience caused by use of an indwelling urinary catheter.

UroShield Testimonials

“Patients treated with the UroShield have less catheter related pain and discomfort, require less anti-pain, less anti-spasmodic medications, and require less nursing attention. This results in enhanced patient comfort and lower overall costs. The product is simple to use and maintain. It is a great new tool in our arsenal to help our patients.”

Dr. Ofer Shenfeld Head, Dept. of Urology, Shaare Zedek Medical Center, Jerusalem, ISRAEL

“MC has an indwelling catheter as a result of loss of bladder control due to Multiple-Sclerosis. MC suffered from bladder spasms, pain, burning and discomfort at the catheter site. Since using UroShield:

  • MC noticed less pain and discomfort within hours.
  • After one day, MC slept through the night, and continues to sleep through the night more often than not.
  • Urinary tract infections have been eliminated with ongoing treatment.
  • Bladder spams have been reduced dramatically.

MC is generally feeling better and has a greater desire to be social, thereby improving relationships and overall quality of life”

MC 72 Years Old - Female

“Following the use of the indwelling catheter, I started experiencing frequent urinary tract infection episodes. Every few months I was hospitalized and treated with antibiotics to fight the reoccurring infections. Three years ago I started using NanoVibronix’s UroShield. I must say that it has improved my quality of life dramatically; I’m so used to it now that when I remove it in order to go the shower I feel “something is missing” in my body. God bless you.”

YI 84 Years Old - Male

“Amazing! The NanoVibronix UroShield has completely changed my life! I tried almost every other solution and still suffered from frequent and painful issues with my Foley Catheter. Using UroShield, I experienced results almost immediately. No more discomfort! I have my life back thanks to UroShield.

TJK 54 year old male

“I’ve been using a urinary catheter for years. Over that time, I have dealt with the chronic pain and discomfort that comes with daily catheter use. The NanoVibronix UroShield is different. It’s easy to use and has dramatically improved my experience. Thank you.”

BF 48 year old female

“I’m impressed with the dramatic effect the device provides in enhancing chronic patients’ quality of life by reducing pain, spasm and number of required catheter replacements. In addition, preliminary results in these patients suggest a lower rate of bacteriuria and related UTI. The product is simple to use and maintain. I’m convinced that the UroShield will open a new era in treating urinary catheter related symptoms.”

Dr. Yoram Siegel Head of Endo-urology unit, Assaf Harofeh Medical Center, Zrifin, ISRAEL

“I was very impressed when I first heard about the UroShield technology. Our interest led to first clinical studies, with astonishing results towards biofilm prevention and UTI reduction. I am convinced that the UroShield technology is an important new tool to overcome this problem, hereby reducing significantly the costs of treatment and antibiotic resistance patterns.

Surface Acoustic Waves (SAW) Technology

TURNING AN INDWELLING CATHETER INTO A THERAPEUTIC DEVICE

NanoVibronix proprietary ultrasound technology enables creation of a miniature ultrasound transducer that can generate low-frequency, low-intensity ultrasound energy through flexible materials surfaces.

The UroShield device harnesses the power of this technology to generate ultrasonic surface acoustic waves (SAW) via an actuator that is clipped on to the external portion of any indwelling urinary catheter. The waves are transmitted directly onto the indwelling catheters at frequencies of 90 kHz and propagate throughout the catheters entire length and on both its inner and outer lumens.

These waves acquire two vectors as shown in Fig. 1A. A longitudinal vector that spreads parallel to the wave propagation X axis along the catheter surface, triggering horizontal particle displacement.

Another transversal compression wave component develops on the Y axis in the direction of surrounding tissues or fluid. Consequently, the entire catheter is covered with a virtual vibrating acoustic coating.

FAQs

most common questions already answered

Yes. It can be used with catheters made of silicone, polyvinyl chloride (PVC), latex rubber, siliconised latex, and all other catheter materials.
The UroShield® can be used with urinary catheter sizes 14, 16, 18, 20, and 22 French.
No. The actuator is for use with a single catheter only and should be disposed of when the catheter is replaced.

UroShield is composed of two components:

Disposable Clip – Intended for single use and to be discarded with catheter replacement.

Driver – A portable unit (AC or battery powered) that provides power to the disposable clip.

The ultrasonic waves generated by the clip create an acoustic shield on the surfaces of the catheter to interfere with the attachment of bacteria, prevent bacterial biofilm formation, the development of infections and may eliminate or reduce the need for antibiotics.

UroShield is designed to:

  • Prevents biofilm formation
  • Decreases bacteriuria/UTI
  • Reduces catheter pain and discomfort
  • Increases antibiotic efficacy

The clip-on UroShield can be attached to all external urinary tract catheters providing potential relief from spasm and catheter pain.
