Introducing Micro-hole Zone Technology

Micro-hole Zone Technology ensures** complete bladder emptying* in one free flow. By reducing mucosal suction, it eliminates the need for repositioning and reduces the risk of residual urine and microtrauma.1,2

Learn how Micro-hole Zone Technology works

Intermittent catheters with Micro-hole Zone Technology have 80+ micro-holes, designed to reduce the risk of UTIs. Key benefits of Micro-hole Zone Technology are1:

  • One free flow – The urine flow only stops when the bladder is completely emptied*
  • No repositioning – There is no need to reposition the catheter as mucosal suction is reduced
  • Less risk of UTIs – Designed to reduce the risk of UTIs by minimizing residual urine and bladder microtrauma

*The Micro-hole Zone Technology catheter has close to no flow stops for complete bladder emptying, defined as <10 mL, Landauro, et. al, (2023), (N=42), when used in accordance with product 'Instructions for use'. Individual results may vary.

**When used in accordance to product 'Instructions for Use'

Drains the urine in one free flow

Micro-hole Zone Technology
Designed to drain urine at the bottom of the bladder with 80+ micro-holes. 1
Conventional eyelet catheter
Two eyelets for urine draining.

No need for repositioning

Micro-hole Zone Technology
Reduces mucosal suction of the bladder wall. 1
Conventional eyelet catheter
May lead to mucosal suction, causing the urine flow to stop. These flow stops may give a false indication of an emptied bladder. 2,4

Less risk of UTIs

Micro-hole Zone Technology
Is designed to reduce the risk of UTIs. 1,3
Conventional eyelet catheter
If residual urine is left behind in the bladder, bacteria may thrive and potentially lead to the development of UTIs. 5,6

Prior to use, refer to product labeling for complete product instructions for use, contraindications, warnings and precautions.

Luja Coudé is indicated for use by patients with urine retention and patients with a post void residual volume (PVR) due to neurogenic and non-neurogenic voiding dysfunction. The catheter is inserted into the urethra to reach the bladder allowing urine to drain. The product is for adult male patients only. Apply with caution if the patient produces urine with many particles clearly distinguishable by the naked eye, as it may lead to transient urine retention.  See the device manual for detailed information regarding the implant procedure, contraindications, warnings, precautions, and potential complications/adverse events.
