The Conveen Security+ external catheter is one of those discreet medical helpers you only notice when it fails - and that is exactly what urology nurse Martin Jensen says it is built to avoid. In his clinic, patients describe the smooth silicone surface as almost invisible under loose cotton trousers.

How Conveen Security+ works

Conveen Security+ is a self-sealing male external catheter intended for men with urinary incontinence who prefer a non-invasive solution to indwelling catheters. The device uses medical-grade silicone instead of natural rubber latex, eliminating the risk of latex-induced allergic reactions.

The catheter has an integrated adhesive that forms a seal around the penis without requiring tape or an extra adhesive strip. The adhesive aims to balance secure attachment with skin-friendlier removal, an aspect Coloplast highlights for users with fragile or aging skin on its product materials.

Design details users notice

Urologists point out that the multiple available sizes - for example 25 mm, 30 mm and 35 mm diameters - make fitting more precise and help avoid leakage or constriction. The Security+ version includes a reinforced funnel area where the urine drainage tube connects, aiming to reduce kinking during movement. Patients often mention that this area feels slightly firmer to the touch than the sheath itself, giving a tactile cue for secure tube connection.

Martin Jensen describes a typical fitting: the silicone sheath rolls on with a quiet, rubbery slip and sits flush without sharp edges. For many of his patients, the absence of the typical latex smell is a small but convincing detail that makes wearing the catheter for several hours less intrusive.

Intended use and patient profile

Conveen Security+ is designed primarily for adult men with moderate to severe incontinence who retain the ability to urinate but cannot control the timing. It channels urine into a bedside or leg bag via standard tubing, allowing longer wear during daytime activities or at night.

Continence specialist Dr. Anne Holm notes that many of her patients choose external catheters to avoid urethral irritation and infection risks associated with indwelling Foley catheters, particularly during rehabilitation after surgery. For some, the psychological benefit of not having an internal device is just as relevant as the physical comfort.

Latex-free and skin considerations

Coloplast emphasises that Conveen Security+ contains no natural rubber latex, targeting users with known latex sensitivity or those at risk of developing it through long-term exposure. The transparent silicone sheath allows visual inspection of the skin underneath, which Holm calls helpful for monitoring redness or early pressure marks.

The adhesive area is thinner than the drainage funnel, which many users experience as flexing slightly with movement rather than cutting into the skin. In practice, this is meant to reduce shear forces that can aggravate fragile penile skin, particularly in older men or those with vascular disease.

Handling, storage and replacement

The single-use catheter is supplied sterile, generally in boxes of 30 or 35 pieces depending on the size variant, and should be stored in a dry place at room temperature until use. Jensen advises his patients to replace the catheter at least once per day and not to attempt cleaning and reusing it, both for hygiene and adhesive performance.

Application typically follows a short routine: wash and dry the skin thoroughly, trim hair if needed, then unroll the sheath smoothly along the shaft and hold it briefly to let the adhesive bond. Removal at night involves gently rolling the sheath back, which many users describe as a clean process without residue if the skin was fully dry at application.

Market context and Coloplast shares

Continence care products, including external catheters like Conveen Security+, form part of Coloplast A/S's key business segments alongside ostomy and wound care, which the Danish manufacturer highlights in its annual reports. For retail investors, this stable portfolio in long-term care markets is one reason the Coloplast A/S share price on Nasdaq Copenhagen remains closely watched.
