Urology Stent

UVENTA™ Ureteral Stent

Indication

Malignant Ureteral Obstruction(MUO)

Features

Structure
Triple layered construction
Outer stent: Gives high friction coefficient to prevent migration
Three(3) platinum radiopaque markers at each end of stent


PTFE(Teflon) membrane: Prevents tissue ingrowth
Inner stent: Reinforces overall radial force
Both ends: Lower radial force and encapsulated by PTFE to prevent reactive hyperplasia


Preloaded type delivery system

Outer sheath: Metal braided tube contributes excellent pushability and trackability
Radiopaque ring at outer sheath: Shows deploying progression
Yellow marker: Cystoscopic marker to place stent at orifice border
Inner stent: Reinforces overall radial force
Three(3) Radiopaque markers: Fluoroscopic markers for accurate
placement. Accordance with stent loaded portion - Proximal, Center and Distal

UVENTA™ Urethral Stent

Indication

Benign and Malignant Urethral Obstruction

Features

Structure

Different magnitudes of segmental radial force may reduce reactive hyperplasia
Full silicone covered to prevent tissue in-growth
Three(3) platinum radiopaque markers at each end of stent
Four(4) anti-migration anchors at the distal end prevent the risk of migration
Retrieval string facilitates easy removal of stent
