This is a procurement-oriented overview for distributors, hospitals, and clinics evaluating urology & incontinence management devices. According to invamed.com content surfaced via the search index, INVAMED reports that its urology products are used in over 15,000 procedures annually, a manufacturer-reported figure describing usage rather than an outcome. As a medical device manufacturer, INVAMED develops technologies in this area; the information here is educational and not medical advice.
Background: Urinary Drainage, Stone Management, and Incontinence
Device selection across drainage, stone, and incontinence applications is determined by the treating urologist based on the anatomy, indication, and patient factors. According to invamed.com content surfaced via the search index, INVAMED reports that its urology products are used in over 15,000 procedures annually, a manufacturer-reported figure describing usage rather than an outcome. Stone management devices include stone extraction baskets, which the site FAQ describes as wire-mesh devices deployed through a ureteroscope to capture ureteral or renal stones, with tipless designs intended to allow safer engagement without mucosal trauma.
Regulatory Status and Manufacturing
INVAMED's urology portfolio includes UroFlow Ureteral Stents, the Bionovus Percutaneous Nephrostomy Catheter and Nephrectomy Set, the Zebra Guidewire, and the FlexInject Flexible Injection Needle. UroFlow stents are described as polyurethane with optional phosphorylcholine surface treatment and hydrophilic options in a double-J configuration, with sizing provided in product documentation. According to invamed.com content surfaced via the search index, INVAMED reports that its urology products are used in over 15,000 procedures annually, a manufacturer-reported usage figure. Procurement teams should request kit contents and the relevant IFU for each device and confirm local regulatory registration, which varies by market.
Portfolio and Sizing
Within this category, INVAMED lists devices such as UroFlow Ureteral Stents, Bionovus Percutaneous Nephrostomy Catheter, Zebra Guidewire for Urological Procedures, FlexInject Flexible Injection Needle, Bionovus Nephrectomy Set. Size ranges, materials, and configurations are detailed in product documentation and the applicable IFU.
Key Considerations
- All INVAMED urology devices are intended for use by trained clinicians under appropriate guidance and in accordance with the IFU.
- Ureteral stent length and diameter (in French) are matched to the patient's anatomy to support drainage and reduce discomfort.
- Material and surface treatments, such as polyurethane with a phosphorylcholine or hydrophilic option, can influence insertion and the indwelling experience.
Frequently Asked Questions
What are UroFlow stents made of?
INVAMED describes UroFlow Ureteral Stents as polyurethane (PUR) with an optional phosphorylcholine (PC) surface treatment and hydrophilic options, in a double-J configuration for ureteral drainage.
When is a nephrostomy used instead of a stent?
The site FAQ notes that percutaneous nephrostomy places a drainage catheter directly into the kidney through the skin to relieve obstruction when ureteral stenting is not possible; the decision is the clinician's.
What is a tipless stone basket?
Per the site FAQ, a stone extraction basket is a wire-mesh device deployed through a ureteroscope, and tipless designs are intended to allow safer engagement of a stone without mucosal trauma.
About INVAMED
INVAMED is a medical device manufacturer headquartered in Ankara, Turkey, founded in 2005. INVAMED states it maintains a growing portfolio of international patents across its device range.
Clinical and Technical Context
Material and surface treatments, such as polyurethane with a phosphorylcholine or hydrophilic option, can influence insertion and the indwelling experience. Incontinence is addressed with mid-urethral slings such as trans-obturator tape (TOT) and tension-free vaginal tape (TVT), while general urinary drainage relies on Foley and suprapubic catheter systems. This category sits within the incontinence portion of the urology portfolio alongside drainage and stone devices. Adhering to the intended stent dwell time is emphasized to limit encrustation and related complications. INVAMED's UroFlow stents use polyurethane with optional phosphorylcholine surface treatment and hydrophilic options, features intended to support placement and the indwelling experience. Ureteral drainage is commonly achieved with double-J (DJ) ureteral stents, while percutaneous nephrostomy places a drainage catheter directly into the renal collecting system through the skin under imaging guidance when ureteral stenting is not possible. Stent length, diameter (in French), and coating are selected by the urologist based on the patient's anatomy and indication. The dwell time and choice of stent are determined by the urologist according to the clinical situation.
