Colon & Duodenal Stents
The colon and duodenal stents make use of two fundamentally different stent production technologies:
"S":
Fixed, braided stent structure
consisting of one nitinol wire that is braided into a tube shape. This gives
the stent its characteristic form through the memory effect, and it reassumes
this shape every time it is deformed.
"D":
In contrast to the "S"
sent, in a "D" stent two nitinol wires are braided together. This
allows the stent to maintain its form at a defined radial strength through the
memory effect in the radial direction. It can be retracted in the axial
direction to bend while the stent maintains its form. This provides an ideal
balance of radial strength and flexibility, and is an advantage particularly if
the stent needs to be placed in tortuous anatomy.
S Colonic & Duodenal Stent (Uncovered)
Closed-cell with braided structure
High degree of flexibility and optimum radial strength
Both head ends (8 mm larger than the rear) contribute to minimizing migration
Silicone coating and soft, round ends reduce the ingrowth of tissue and the hyperplasia response
Visible green retrieval string for easy removal
Radiopaque markers: Four on both ends and two in the middle
D Colonic & Duodenal Stent (Uncovered)
Immovable cell with woven structure
Minimal shortening for exact positioning
Optimum combination of radial and axial strength for maintaining the luminal patency in tortuous anatomy.
Radiopaque markers: Three on both ends and two in the middle
