From the multidisciplinary network ENIUS, we want to create a meeting point for researchers, clinicians, industrial partners and manufacturers interested in accurate and up-to-date information related to urinary stent Research and Development. It will provide data regarding the leading research groups, manufacturers, patents, as well as recent scientific literature in this area of knowledge.
This website is born with the purpose of being a source of information on all aspects related to urinary stent development, including the following:
Biodegradable Ureteral Stent intended to be used to temporarily drain obstructed ureter. The patented structural hydrogel has a homogenous degradation.

The INLAY OPTIMA® stent continues the legacy of the BARD® INLAY® stent.
BARD® offers multiple stent choices in design, length, and coating to assure you the right stent match with each procedure and anatomical requirement. The INLAY® ureteral stent offers many advantages.
Its tapered tip and lubricious coating promote smooth insertion and effective negotiation around obstructions. It has a hydrophilic coating which when activated, creates a 'cushion' between the stent and tissue for smooth, frictionless insertion. In addition, the stent softens up to 50% at body temperature, promoting enhanced comfort and minimal friction. The stent comes individually packaged in a single use, sterile configuration.
Features
BD Urinary Diversion Stents have been designed to provide secure placement in the renal pelvis while allowing drainage of urine from the kidney to an external stoma.
It is packaged with a lubricious coated guidewire, push catheter and comes in a single use, sterile package.
