Strecker tantalum stent

Other types of stents such as the Strecker tantalum stent (SoLT and Papp 1993), the Strecker Nitinol stent (Strecker et al. 1995) or modified and covered Gianturco stents (Song et al. 1993) have been used only occasionally and not much experience exists with these stents. Recently, however, two series of 19 and 24 patients have been published advocating covered metallic expandable stents for prevention of tumour ingrowth after stenting for gastroduodenal obstruction (Jung et al. 2000 Park et al. 2001). 

Due to the development of newer self-expanding stents, which combine the flexibility of the tantalum stent with the strength to oppose compression of stainless steel stents, the Strecker tantalum stent is no longer produced.

Balloon-expandable stents for example, Palmaz (Johnson 8c Johnson, Warren, NJ) and Tantalum Strecker (Boston Scientific). These stents are inserted mounted on an angioplasty balloon catheter and expanded by the balloon when in an optimum position across the stricture. Balloon-expandable stents are difficult to deploy around curves and have reduced radial force compared... 

The second balloon-expandable stent type has been made from a single tantalum filament, which was woven into a cylindrical wire mesh. Again, the choice of thickness of the tantalum wire and the knitting technique determines the mechanical properties of this stent type. This particular stent type has been known as the Strecker stent (Boston Scientific, Natick, MA) (Strecker et al. 1990). This stent requires balloon dilatation for deployment like the Palmaz type stents. Generally, it is more flexible but also less resistant to compressive forces than the stainless steel balloon-expandable stents. Stents for use in the respiratory system came in lengths between 20 and 40 mm, and were expandable to diameters between 5 and 11 mm. Due to its relatively low radial forces, this particular stent had the unique feature of possible stent removal, thus it can be used for temporary stenting (Schmidt et al. 1999 Witt et al. 1997).
