Groningen ® 4 L.R. / U.L.R.

Clinical application

The Groningen was the first indwelling prosthesis. There are two versions with different, overall lower resistances. Anterograde insertion using an insertion tube is now possible. The Groningen® 4 prosthesis is used under the same circumstances as the Provox® 2 and the Blom-Singer® Classic 20fr prostheses.

Type of prosthesis:Low-resistance indwelling prosthesis
Outer diameter of shaft:7 mm (standard) and 8 mm
Shaft lengths:5 mm, 7 mm, 8 mm, 9 mm, 11 mm, 13 mm
Material:medical-grade silicone
Valve type:flap valve available with two levels of resistance (low resistance = L.R., ultra low resistance = U.L.R.)
Method of insertion:anterograde using insertion tube
Indication:standard prosthesis
Biofilm resistance:no
Underpressure stability:no
Non-fatiguing valve mechanism:no
Prevalence:local (Groningen, Holland)
