Nitinol strecker

The nitinol Strecker stent was an earlier version of the uncovered Ultraflex stent and is very similar to it... 

This stent has been modified from the original Strecker stent and consists of a woven nitinol mesh. It is available in covered and uncovered versions (Fig. 2.4), and... 

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). 

In the series of Strecker stent placement in 21 patients, complications were reported in two. One stent compression and one stent dislocation occurred in two patients. Both stents were removed without problems (WiTT et al. 1997). In a smaller trial, one Strecker stent out of five dislocated 6 days after placement (ScHMiDT et al. 1999). In the series of Hauck et al. (1997), tumor ingrowth through the stent was seen in nine of 51 patients treated with Strecker or nitinol stents. Stent deformation occurred only with Strecker stents ( =12), but not in nitinol stents. Mucus retention was a frequent problem within the first 7 days after stent placement (39%).
