ABSTRACT:
A gripping fixture suitable for use in stent securement testing is described. The gripping fixture includes a housing having a chamber, a rigid perforated tubular member positioned within the chamber, a multiplicity of radially extending pins arranged to slide in the perforations in the tubular member, and an elastic sheath that circumscribes the outer ends of the pins and surrounds the tubular member. A pressure chamber is formed between the housing and the elastic sheath. The gripping fixture also includes a pressure controller for controlling the pressure within the pressure chamber. The pressure applied in the pressure chamber acts on the elastic sheath and may be used to cause some of the pins to engage a stent during the stent securement test to hold the stent in place relative to the gripping fixture while the tensile force required to dislodge the stent from a catheter is measured.
