Claim:
A cap assembly of a cannula comprising: a valve housing having at least one opening formed in line with an axis of said valve housing, said at least one opening being defined by an inner valve housing sidewall; and a first valve positioned at least partially within said valve housing and including a valve body having: a proximal valve section positioned within said valve housing and including an annular shaped valve ring having a proximal surface, a distal surface, an inner perimeter surface, and an outer perimeter surface, a distal valve section extending axially from said proximal valve section and including a valve extension having a proximal end portion, a distal end portion, and a substantially conically shaped medial portion connected to and extending therebetween, and having a plurality of friction-reduction features disposed proximate said distal end portion and extending a distance in said substantially conically shaped medial portion; and a valve opening positioned in said distal end portion of said valve extension and adapted to individually and separately receive therethrough any one of a plurality of different elongate tools each having a different diameter so that when any one of the plurality of elongate tools is positioned through said valve opening a seal is maintained between peripheries of said valve extension surrounding said valve opening and outer peripheries of any one of plurality of elongate tools extending therethrough, wherein said proximal valve section, said distal valve section, and said valve opening comprise said valve body, and wherein said valve body is a singularly formed member.
