This is a technical overview of an INVAMED device within the urology & incontinence management portfolio. 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
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. 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.

Bionovus Nephrectomy Set: Overview
Percutaneous nephrostomy/nephrectomy access set listed on invamed.com as an INVAMED Research & Development product (page title only; no further detail captured).
How It Works and Where It Fits
INVAMED's urology portfolio is organized by function, spanning ureteral stents, percutaneous nephrostomy and nephrectomy sets, guidewires, and injection needles. Each device is intended for use by trained clinicians under appropriate guidance and per the IFU. Double-J stents are typically placed cystoscopically over a guidewire, with the two curled ends providing retention at the kidney and bladder. A ureteral stent is a thin, flexible tube placed within the ureter to maintain drainage of urine from the kidney to the bladder, often after stone treatment or to relieve obstruction.
Key Considerations
- Material and surface treatments, such as polyurethane with a phosphorylcholine or hydrophilic option, can influence insertion and the indwelling experience.
- All INVAMED urology devices are intended for use by trained clinicians under appropriate guidance and in accordance with the IFU.
- Percutaneous nephrostomy is generally reserved for when internal ureteral stenting is not possible, as noted in the site FAQ, and is performed under image guidance.
Frequently Asked Questions
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.
How long can a ureteral stent stay in place?
Ureteral stents have a defined maximum dwell time stated in the device documentation to limit encrustation and other risks, and the exact timing of removal or exchange is set by the urologist.
How many procedures use INVAMED urology products?
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.

Clinical and Technical Context
Stent length, diameter (in French), and coating are selected by the urologist based on the patient's anatomy and indication. The use of such sets and devices is determined by the operating clinician according to the planned procedure. Basket selection and technique are chosen by the operator based on the stone size, location, and anatomy. 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. Material and surface treatments, such as polyurethane with a phosphorylcholine or hydrophilic option, can influence insertion and the indwelling experience. This clinical area covers urinary drainage, stone management, and the treatment of incontinence, using devices that maintain or restore the flow of urine and support the management of stones. The dwell time and choice of stent are determined by the urologist according to the clinical situation. Whether a sling is appropriate, and which approach is used, is determined by the treating clinician.
