Stena Stent Colonic System

Stena Stent Colonic System

A titanio o lega sistema di placche sternali che fornisce rigido fissazione dopo la sternotomia mediana, migliorando stabilità sternale e ridurre i rischi di infezione o deiscenza dopo un intervento di cardiochirurgia.

Informazioni

Stena™ Colonic Stent by Invamed—a global medical device manufacturer—is engineered for endoscopic deployment in colorectal strictures, providing rapid decompression and symptom relief in both malignant and benign obstructions. Featuring a self-expanding design and sturdy radial force, Stena™ ensures stable luminal patency while conforming to the challenging anatomy of the colon.

Self-Expanding Metal Mesh

Typically constructed of nitinol or a flexible metallic alloy, delivering robust radial force to keep colonic segments open in the face of external or intraluminal compression.

Accommodates the colon’s tortuous anatomy, minimizing migration risk and reducing patient discomfort after placement.

Expands promptly upon release, enabling relief from obstructive symptoms and allowing fecal passage or liquid diet quickly.

Suitable for palliative care in advanced colorectal cancer or short-term decompression in benign strictures (e.g., diverticular disease) where stent bridging is required.

Complete obstruction preventing guidewire passage, extremely angulated or perforated lesions, and acute peritonitis scenarios where stenting is not advised.
