Abstract
Disclosed is an apparatus and system that includes an elongated body, a vascular closure device that can occlude a hole in a vessel wall coupled to a distal end of the elongated body, a sleeve assembly and a biasing member arranged to elastically deform coupled between the elongated body and the sleeve assembly, where the elongated body is longitudinally displaceable with respect to the sleeve assembly, wherein the biasing member exerts a force on the elongated body approximately proportional to a longitudinal displacement between the elongated body and the sleeve assembly and where the biasing member is arranged deform a discernible amount when a conforming force sufficient to occlude the hole is applied to the elongated body through the biasing member and the sleeve assembly.
