Claim:
1. An apparatus for occluding a hole in a vessel wall, the apparatus comprising: an elongated body comprising a proximal end and a distal end; a vascular closure device coupled to the distal end of said elongated body, wherein said vascular closure device is constructed and arranged to occlude the hole in the vessel wall; a sleeve assembly comprising a proximal end and a distal end; and a biasing member connecting said elongated body to said sleeve assembly such that retracting said sleeve assembly away from said vascular closure device, when said vascular closure device is implanted within the body of the patient applies tension to said elongated body that elastically deforms said biasing member in a longitudinal direction thereby exerting a force on said vascular closure device approximately proportional to a longitudinal displacement of said elongated body relative to said sleeve assembly; and an indicator coupled to said elongated body, wherein said indicator is positioned to be substantially obscured by said sleeve assembly when a force less than a conforming force is applied to said vascular closure device through said elongated body and wherein said indicator is positioned to be discernible when the conforming force is applied to said elongated body through said biasing member and said sleeve assembly.
